Title: Supercharged Cafe LS650 Post by DennyzfR6 on 10/27/23 at 15:20:22 Hi all, Just opening a topic here for my current Savage (LS650) build. 1. Because I expect challenges down the line and maybe with future issues the combined knowledge on this forum might be able to help. 2. Because I simply want to share to process of the build. First a short intro. I live in the Netherlands, so excuse my English. I own quite a few Ducati's and exactly 1 Suzuki ::) That Suzuki is a project that started 10 years ago. The Project has been on and off during that period. It has seen 3 relocations and a divorce but now finally gets the attention it deserves. It started out with the idea of building the Ryca caferacer. But then I found the topic of Savagebob here on this forum, and a supercharger had to be part of the build. I have an almost complete Ryca kit here in boxes, but almost nothing will be used. So after this build, I will probably have to build another one with the leftover parts ;D The goal is to make it kind of a show bike. But it all has to be functional. . Work for short rides, like the Gentlemans Ride for example and around the block and basically be nice enough to be placed here in the living room. In the last few years I did build a madmax / walking dead style hardtail LS650. (will post a few pics). A 535 Virago bobber and a Ducati scrambler style bike. All from lower budget, almost unsalvageable bikes. But now it is time to finish the Charged Savage. I cannot weld aluminium, nor am I an expert in fabrication so I am getting help from a custom builder. And as said, I want this bike to be close to perfect (in my eyes at least). Other than this I am reasonable capable when it comes to working on bikes.

Title: Re: Supercharged Cafe LS650 Post by DennyzfR6 on 10/27/23 at 15:41:51 In the pictures above and below, some steps have already been done. The real wheel has been respoked to a 19". The swingarm is shaved, holes welded, and it has been adapted to accept the new size wheel. The frame has been cleaned up a bit. The front end has been lowered. The lower fork sliders are shaved and polished. Clipons have been installed and also a billet top yoke http://https://i.postimg.cc/8cYhMsMC/IMG-20220517-WA0032.jpg Next was changing the frame |

Title: Re: Supercharged Cafe LS650 Post by DennyzfR6 on 10/28/23 at 00:45:21 @TheSneeze, thanks! Last night I went through your entire tracker build aswell! Looks great! Because of the stance of the bike, the way I want to route the exhaust and to create space for the supercharger setup, the frame has to be adjusted. This also meant relocating the top shock mounts and try to make the shock position as symmetrical as possible by moving the left shock inwards as to slim the bike down a bit from the rear: http://https://i.postimg.cc/kMYNkYzd/IMG-20220810-WA0000.jpg http://https://i.postimg.cc/vH17MLwx/IMG-20220810-WA0003-1.jpg http://https://i.postimg.cc/Y2V5M069/IMG-20220813-WA0010.jpg |

Title: Re: Supercharged Cafe LS650 Post by DennyzfR6 on 10/28/23 at 00:57:39 As can be seen the engine is also back in the frame. It is a low mileage 5 speed. I should still have the odometer somewhere... but yeah.. you know how that goes :-? The engine has been refreshed a few years back. Honed the cilinder, put in new rings, clearance and everything done. All new gaskets and filters. It has been waiting to be installed back in the bike ever since.. I was temped to put the fresh engine in the mad max LS650 but resisted.. keeping it stashed away for its original purpose :) The upgraded VerSlavy cam chain adjuster has also been placed. The engine was painted and polished, but that will have to be done again after this many years. :-/ http://https://i.postimg.cc/kXkQ5671/IMG-20220810-WA0037.jpg In this pic the lower shock mount has been moved inwards aswell ;D http://https://i.postimg.cc/XYdwBjJV/IMG-20221220-WA0020.jpg |

Title: Re: Supercharged Cafe LS650 Post by DennyzfR6 on 10/28/23 at 01:06:52 Because of moving the left schock inwards something had to be done about the rear belt pulley. I really wanted to keep the belt and not convert it to a chain drive (even though that would make a lot of things so much easier) But I like the idea of it being quite unique for a cafe bike. And also, together with the supercharger pulleys on the same side it will all be belts on the left side. However the standard pulley is way too bulky so we changed that. http://https://i.postimg.cc/CLv4fhHq/IMG-20220810-WA0050.jpg http://https://i.postimg.cc/CxzsG3m6/IMG-20221220-WA0013.jpg Which I think results in a much sleaker look whilst retaining the belt drive ;D In the backround the testfit supercharger is also visible already 8-) http://https://i.postimg.cc/mTzVGRTp/IMG-20221220-WA0018.jpg |

Title: Re: Supercharged Cafe LS650 Post by DennyzfR6 on 10/28/23 at 05:26:41 Next on the 'To Do' list was the front brake disc. The rear pulley now has 8 bolts to keep the outer rim in place, so the front disc also needs to have 8 bobbins. Details matter ;) Suprise, not many brake discs with 8 bobbins! :-/ I found the Honda VTR 1000 F 1997 -2006, with 296mm disc and the Suzuki TL 1000 1996 - 2001 with 320 mm disc. Suzuki GSR 600 2006-2009 - 310mm I went for the GSR ! It's close in size of the rear pulley and just looks a bit more badass 8-) Some new semi floating bobbins and some machining on the original disc, retaining the center to match the rear pulley design and here we are: http://https://i.postimg.cc/fyC4nNgd/IMG-20230128-WA0002.jpg Next step, starting work on mounting the supercharger: http://https://i.postimg.cc/fy755V7N/Afbeelding-van-Whats-App-op-2023-10-02-om-15-48-20-4e606fac.jpg |

Title: Re: Supercharged Cafe LS650 Post by Ruttly on 10/28/23 at 09:59:49 Impressive work , a bit more frame length and a nice shock angle. In Ryca configuration I find seat a bit short needing more to the rear and I’m short. Top of rear shock should be behind riders butt not pointing at your hip. Very cool I bet lots are watching you. 8-) |

Title: Re: Supercharged Cafe LS650 Post by zevenenergie on 10/28/23 at 10:18:29 Cool how you are so experimental with your savage. I'm going to follow this topic. In which part of the Netherlands do you live? I live in the westland. |

Thanks! The Ryca config is offcourse a lot more simple to apply to the bike without the need to do any serious modifications. But yes I do agree. In the pictures so far.. the bike is still very slightly leaned over on the rear. But some future very nice shocks will put it a bit more on its nose. 8-) |

Title: Re: Supercharged Cafe LS650 Post by DennyzfR6 on 10/28/23 at 11:19:18 Oke... so on with the build.. The position of the charger was good in the post above.. but.. I wanted a bit more volume to the plenum, did some research and that seems to help singles on boost. And above all, really needed to have a bit more bling to it. http://https://i.postimg.cc/W1YR8mF6/Afbeelding-van-Whats-App-op-2023-10-02-om-15-58-23-7e6671fa.jpg http://https://i.postimg.cc/kGN3vkKB/Afbeelding-van-Whats-App-op-2023-10-03-om-13-29-27-f39a5336.jpg http://https://i.postimg.cc/zBKtYqyG/IMG-20231005-WA0006.jpg http://https://i.postimg.cc/zvkx3pSm/Afbeelding-van-Whats-App-op-2023-10-05-om-16-49-17-7d88b0e3.jpg http://https://i.postimg.cc/nrxdHNmY/Afbeelding-van-Whats-App-op-2023-10-05-om-16-49-17-371ae20f.jpg A bit of polishing and there we are. 8-) A 25psi bleed/pop off valve is on order and will be placed in the plenum aswell when it arrives. To hopefully take care of any backfire detonation and boostspikes. http://https://i.postimg.cc/4NyhMB7Y/Afbeelding-van-Whats-App-op-2023-10-10-om-15-41-54-a2dbd013.jpg |

Title: Re: Supercharged Cafe LS650 Post by DennyzfR6 on 10/28/23 at 11:51:06 Now to get some fuel for the bang.. In the topic of Savagebob, after some trial and error he landed on a 40mm CV carb for his setup , and he also posted some of his findings and settings for this setup. To play it safe, I have gone the same route. It will at least give me a ballpark setting on where to start.. when we finally get to running the bike. Because bling is the theme for this bike, this is also made out of aluminium. http://https://i.postimg.cc/650x2xBP/Afbeelding-van-Whats-App-op-2023-10-02-om-16-00-26-2463c993.jpg http://https://i.postimg.cc/Wp0vVJCT/Afbeelding-van-Whats-App-op-2023-10-19-om-19-36-26-6d691834.jpg When everyting is connected it looks like this. ;D ;D Support for the charger will have to be created offcourse, in the most elegant way we can think of.. but that is for later. The final solution for this will also depend on the exact routing of the exhaust in combination with the location of the belts and the tensioners. So that is still to come. http://https://i.postimg.cc/rybzzWFb/Afbeelding-van-Whats-App-op-2023-10-19-om-19-57-29-d330dd01.jpg http://https://i.postimg.cc/KYC6SZ51/Afbeelding-van-Whats-App-op-2023-10-19-om-19-57-07-0f46a806.jpg http://https://i.postimg.cc/3xx52fRx/Afbeelding-van-Whats-App-op-2023-10-24-om-15-22-45-4dce8782.jpg http://https://i.postimg.cc/zfyscLTm/Afbeelding-van-Whats-App-op-2023-10-24-om-15-22-45-fdfa88ac.jpg |

Title: Re: Supercharged Cafe LS650 Post by DennyzfR6 on 10/29/23 at 01:42:23 Thanks all! ;D We are getting closer to the current situation, but still some other steps that we are already working on. The start has been made for the drive of the charger. A new bolt is machined to replace the flywheel bolt and will act as the driveshaft for the supercharger. A bushing will be welded in the crankcase which will hold the oil seal and the rollerbearing. That is currently on the way. The hole in the case has been centered and drilled. http://https://i.postimg.cc/4xWMxLDh/Afbeelding-van-Whats-App-op-2023-10-25-om-11-00-51-4a71470e.jpg http://https://i.postimg.cc/7LbRG14t/Afbeelding-van-Whats-App-op-2023-10-25-om-11-00-52-9b6177d4.jpg |

Title: Re: Supercharged Cafe LS650 Post by DennyzfR6 on 10/29/23 at 02:07:21 Next is the fabrication of a bracket to hold the new carb in place. It is currently underway. The challenge however, is how the apply an inlet filter or inlet kelk to the carb. Mainly because I want to keep the dept as minimal as possible.. and again. it has to look clean and with a bit of bling and not too bulky. The bracket has to be connected to the frame, but also has to be removable to easily take off the carb and access other parts of the bike. This is the current phase. It will have to be slimmed down a little bit more and be bent to go under the carb slightly. Hopefully this way the carb will seem to 'float' a bit more and keep everything as 'open' and 'light' as possible. http://https://i.postimg.cc/CM955Yyb/Afbeelding-van-Whats-App-op-2023-10-24-om-15-23-35-82e1c531.jpg The current plan is to machine down an aluminium inlet kelk and weld it directly on to the bracket. And make it as shallow as possible. We will have to see how this works out ::) http://https://www.carburateurwinkel.nl/contents/media/40-60g_aanzuigkelk_bolt-on_40_mm_diameter_50_mm_lang_weber_dellorto_solex_gaas_filter_carburateur_winkel_002_20230125152954.jpg |

Title: Re: Supercharged Cafe LS650 Post by DragBikeMike on 10/29/23 at 02:23:27 That is an impressive project. Very nice work. Please keep the posts comin. I'm very curious to see the finished product and to hear how it runs. I suspect the tuning will be a challenge. Let us know how you deal with the carburetion, advance curve, boost, etc. How many pounds of boost do you think it can handle? |

regarding boost etc.. The only knowledge I have is completely based off of Savagebob and his topic here on this forum. So the goal is to run it at around 10 psi if possible. I am not necessarily looking for major hp gains. It just has to function properly, be rideable, generate something extra and look the part. 8-) |

Title: Re: Supercharged Cafe LS650 Post by DennyzfR6 on 10/30/23 at 06:44:47 Parts are being created for driving the charger, so currently waiting on these. ::) Therefore I have been shopping to find some goodies for the bike. As stated multiple times already ::) , one of the goals for the bike is to make ik look as nice as possible. So with this in mind... 8-) http://https://i.postimg.cc/WpnZbw8J/Afbeelding-van-Whats-App-op-2023-10-24-om-15-22-08-1c7380d6.jpg http://https://i.postimg.cc/hvnsH8n1/Afbeelding-van-Whats-App-op-2023-10-24-om-15-22-08-96e2b26a.jpg It was quite a search trying to find Ohlins dual shocks that have the correct lengt for my application. With the correct look and would also still work with such a light bike as the Savage. Basically I looked for the correct height with the lowest N/mm rate for the springs.. and corresponded this to which bike they are used for. Mainly checking the weight of the model. After a lot of scrolling on the internet I landed on the Öhlins STX for a Kawasaki ZRX 400. The preload can be dialed back quite a bit, and softer springs are available if it is still too harsh. We'll just have to see. They have been test fitted and it looks amazing! (did not take any pictures) Do need to make some small changes to the lower shock mounts on the bike. During further fabrication solid rods will be placed on the bike to not damage the shocks. So it will be quite some time before they are back on. The shocks were also needed to measure the available space between the seat and the tire on maximum compression because in between something will be fitted. ;) http://https://i.postimg.cc/3Nn0S3NZ/Afbeelding-van-Whats-App-op-2023-10-24-om-15-22-08-163848ba.jpg And with the arrival of the latter, we can also continue with the front brake project. The original brackets for the brake will be removed.. and a new one will be fabricated. :) All the interesting and fancy stuff.. including SC and exhaust etc will be on the left side of the bike. So the side stand will be moved over to the other side of the bike.. An added benefit is that if any possible leakage might happen with the supercharger driveshaft coming through he statorcover (even though we are placing a seperate seal) this should help. http://https://i.postimg.cc/dV7Z6PY8/Afbeelding-van-Whats-App-op-2023-10-27-om-11-41-18-ebf50ed9.jpg More stuff is about to arrive! |

Title: Re: Supercharged Cafe LS650 Post by DennyzfR6 on 10/31/23 at 11:28:55 Work on the front brake continues: http://https://i.postimg.cc/J7FvYg3W/Afbeelding-van-Whats-App-op-2023-10-31-om-19-20-56-59eed1b2.jpg http://https://i.postimg.cc/Mp7LTpCW/Afbeelding-van-Whats-App-op-2023-10-31-om-17-23-11-aac1ea4d.jpg http://https://i.postimg.cc/fy1P3tWb/Afbeelding-van-Whats-App-op-2023-10-31-om-17-23-11-75e71eff.jpg http://https://i.postimg.cc/mgfqBH6X/Afbeelding-van-Whats-App-op-2023-10-31-om-17-23-11-23227038.jpg |

Title: Re: Supercharged Cafe LS650 Post by TheSneeze on 10/31/23 at 16:39:25 Bling bling!! I wanted Ohlins on my Kawasaki, but just couldn't justify the expense. They are very proud of their shocks... :o |

Title: Re: Supercharged Cafe LS650 Post by Ruttly on 10/31/23 at 22:53:53 I had a set of Ohlins once , traded them for a running RD250 , real nice bike. |

True! But after some searching online I found a shop in Estonia (of all places) that was very reasonable priced. After some digging around it seemed legit. Also ordered the brembo caliper there. Saved me hundreds of euros. Shipping wasnt too bad either. Internet can be a wonderful place ;D |

Title: Re: Supercharged Cafe LS650 Post by DennyzfR6 on 11/01/23 at 12:59:39 More progress on the front brake has been made ;D Also, new parts have arrived and we started on the exhaust.. but will save those updates for later. Coming week will be very busy and don't know how much time I'll be able to work on the Savage.. so spreading out the updates ;) Shaved http://https://i.postimg.cc/rFvVcyNk/Afbeelding-van-Whats-App-op-2023-11-01-om-12-28-48-760b0d52.jpg Welded: http://https://i.postimg.cc/66b6jf7T/Afbeelding-van-Whats-App-op-2023-11-01-om-16-05-05-440b9708.jpg Slowly cooling down.. http://https://i.postimg.cc/15gmLV6B/Afbeelding-van-Whats-App-op-2023-11-01-om-16-05-34-6d194f2a.jpg Tomorrow will be cleaning up the welds and polishing everything ;D |

Title: Re: Supercharged Cafe LS650 Post by zevenenergie on 11/02/23 at 04:26:00 I think it's all very nice for someone who says he has no manufacturing skills, and I think you do. [smiley=thumbsup.gif] But when I look at the front brake that you are changing, I am a little concerned about safety when you soon tear down the roads with your Savage. Let me tell you what I see: http://https://i.imgur.com/DdmuyXy.png Because you have created an opening here, the disc now only has 4 stable spokes left. I don't think that is desirable. :-/ For example, if I look at a Ducati monster 600 the disc has 10 stable spokes. http://https://i.imgur.com/BqjAx5cm.png [smiley=thumbsup.gif] And now I see your brake caliper suspension, and it's being pulled instead of pushed. And then I look at the forces that arise there. http://https://i.imgur.com/uJxiuS1m.png The arrow represents the braking force. If only A were there, you would have lost the caliper after 1 braking attempt. Because A bows. :exclamation So all the force is largely exerted on B. And you had welding done there, so there are welding stresses there. :exclamation The plate you are using seems to me to be no more than 10mm / 8mm? :exclamation The metal most susceptible to metal fatigue is aluminum. Aluminum tends to fatigue quickly when subjected to repetitive loads, such as alternating stresses or loads that vary cyclically. This is because aluminum has a relatively low fatigue limit compared to other metals, meaning it is prone to developing cracks and structural degradation with repeated loading. I wonder what would happen if you stirred the oxygen tanks. https://www.youtube.com/watch?v=Bti9_deF5gs . |

Title: Re: Supercharged Cafe LS650 Post by DennyzfR6 on 11/02/23 at 07:16:51 Thanks for your comments.. extra input is always welcome :) Regarding the disc.. I was wondering how long it would take untill some would speak up regarding this. I have the same worries about it.. and a new center will have to be cut later on before riding actually starts as I am not comfortable with how it currently sits. But with the regards to the brake bracket, I was not really that concerned. But you do have a valid point. I still think it will be oke but will still discuss. Maybe a new design is necessary The plate is 10mm thick.. I will discuss your points with the guy that helps me out. He is the fabricator. Not everything is done by me. Especially the welding etc. He has build a lot of bikes in the past from the ground up so he knows a thing or 2 about what works and what doesnt. |

Title: Re: Supercharged Cafe LS650 Post by verslagen1 on 11/02/23 at 08:12:41 zev is right about the bracket and his concerns are compounded by the weld as you need to reduce the margin of strength by an additional 20%. If this is going to be a hardly ridden show bike, then it's fine, just take it easy on that front brake. If I were doing it, I would've doubled the distance from the fork to the caliper and extended the material above the braking force line. this would eliminate the bending forces from the bracket. and minimized the stresses to the weld. |
|
Title: Re: Supercharged Cafe LS650 Post by TheSneeze on 11/02/23 at 08:54:38 I am not very comfortable with the look of that weld. At the top of that bracket, the fillet cross section is much smaller than the bottom. The top of the bracket will be taking the most load. The other thing I see is, for an aluminum weld, it looks pretty dirty. Aluminum is one of the more difficult metals to weld, and it can never be too clean during weld prep. Impurities affect the weld internally as much as externally. I would bet if that weld was x-rayed it would look like swiss cheese inside. I ran a metal fab shop for 24 years. I certified four of my five welders for aerospace welding, and we were welding on Patriot missile parts for Raytheon. I have a lot of experience with weld processes on a lot of different metals. Not trying to be an armchair quarterback, but I would cut that off, grind all the metal back, reclean the surfaces to be welded, and start over. |

Title: Re: Supercharged Cafe LS650 Post by zevenenergie on 11/02/23 at 10:50:44 Welding cast aluminum is always more difficult than rolled aluminum. It contains much more contamination, also in the form of trapped gases. You must, as it were, first degas the cast part with your flame before adding a welding rod. But that puts a lot of heat into the part and I think the welder was afraid of distortion and sagging. I would have attached the brake caliper to the original mounting points using an adapter. Then the leg will not deform and nothing will get stuck. But a must say, the desing looks very nice... [smiley=thumbsup.gif] |

Title: Re: Supercharged Cafe LS650 Post by DennyzfR6 on 11/02/23 at 11:36:26 He indeed said that he had issues with contamination on the side of the lower fork.. :-? |
|
Title: Re: Supercharged Cafe LS650 Post by DennyzfR6 on 11/15/23 at 01:54:16 Allright.. so we are back at it. Regarding the brakes.. As said earlier a new center for the disc is necessary. This will be done near the end of the build. I also want a new rim for the beltdrive.. the outer one, to center the bolts better. :) This will be done together, and perhaps more things like these will pop up the coming time so then it can all be ordered at once. 8-) Also had a long talk with the builder about the bracket for the front caliper. He is a well known builder here in the Netherlands, and has many published builds in magazines but he usually works on Harleys. He has been doing it for 25+ years. The last bike was a build from the ground up starting with nothing, of which he has done many. He is adament that it will work and is strong enough, and the weld is proper. So I will trust him. I have known him for many years and so far anything he has fabricated has never failed. Nor have I seen any of his custom builds fail. The bike will not be ridden that often, and we'll make sure to check it regularly. http://https://i.postimg.cc/vZRvpj9b/20231114-165844.jpg |

Title: Re: Supercharged Cafe LS650 Post by DennyzfR6 on 11/15/23 at 02:04:51 Parts have also come in.. It took a lot of searching to find a set that looks identical for clutch and brake.. (because symmetry 8-)) with a brake master that is small enough to work with the smaller front brake caliper. Especially the latter was very hard to get a hold of. Multiple cancelled orders as they are no longer produced. It's a 15mm axial brembo master (PSC 15) We'll have to see how this works out.. it might not.. but we'll see. Also to keep the symmetry going, the clutch will have to be converted to hydraulic. Again, we'll see how that works out. http://https://i.postimg.cc/nhv1ZkY7/20231114-165340.jpg http://https://i.postimg.cc/xCdGvSry/20231031-173746.jpg |

Title: Re: Supercharged Cafe LS650 Post by DennyzfR6 on 11/15/23 at 02:21:45 The release valve has come in aswell.. It has been pre-set to 14/15psi. Now time to weld that into the plenum. Work is also progressing on the drive for the charger. Because we do not want the cover to warp, a steel fixation ring is created to keep everything in place. We do not want to use the stator for this, due to the heat and risk of damage etc. It will be welded in small increments to hopefully not create any distortion. The dimensions for the rollerbearing and the oil seal have already been machined into the bushing. http://https://i.postimg.cc/pV6CByL9/20231114-165617.jpg Will machine it down a little bit ;) http://https://i.postimg.cc/J0GqLCP4/20231114-172015.jpg http://https://i.postimg.cc/WzC7pYHm/20231114-171727.jpg http://https://i.postimg.cc/k4jczgNp/20231114-171753.jpg |

Title: Re: Supercharged Cafe LS650 Post by DennyzfR6 on 11/20/23 at 01:46:32 Because we are waiting on parts to be fabricated for the drive of the charger, and also waiting on the inlet kelk etc.. we are making a start with the exhaust. Because the bike is a bit of a show bike a new route for the exhaust will be created. It is closer to the head so we'll see about heat etc. Wrapping is an option. It does not get that hot here in the Netherlands.. also we have higher octane fuel at the pump.. making excuses. We'll just have to see. :-? http://https://i.postimg.cc/fRzpZnrN/IMG-20231012-WA0016.jpg http://https://i.postimg.cc/KjhpHdMC/IMG-20231012-WA0024.jpg http://https://i.postimg.cc/prQcbqQr/IMG-20231012-WA0026.jpg http://https://i.postimg.cc/ydZrnVkF/Afbeelding-van-Whats-App-op-2023-10-25-om-11-00-51-b3d60c6b.jpg http://https://i.postimg.cc/nL5PvscF/Afbeelding-van-Whats-App-op-2023-10-25-om-11-00-51-94e5ab7d.jpg http://https://i.postimg.cc/fLgc5gD4/20231031-172636.jpg |

Title: Re: Supercharged Cafe LS650 Post by DragBikeMike on 11/20/23 at 09:55:21 DennyZ, this build is slick. Lovin the header and of course the huffer. The reservoir with the blowoff valve looks like a good idea. I don’t know much about superchargers. Does the blowoff have enough capacity to protect the blower in the event of an intake backfire? Your gonna need a serious clutch to hold the power. Very nice work. Hey moderators, is there any reason why this build is in the Café? Shouldn’t it be in Rubber Side Down? Not complaining, just curious. |
|
Title: Re: Supercharged Cafe LS650 Post by DennyzfR6 on 11/21/23 at 05:03:57 @DragBikeMike Thanks! The blowoff valve should be big enough. I had a smaller one but with the backfire in mind I upgraded to a larger one. But this is based on the information from Savagebob here on this forum. I have to mention again that he has a great topic on this forum where he has already performed a similar build with regards to the supercharger and that this was the inspiration for my current build. https://suzukisavage.com/cgi-bin/YaBB.pl?num=1372223359 So credit goes to him as far as the basics and the setup for the charger. :) The valve is a similar one he seemed to be using, I specifically looked for this. |

Title: Re: Supercharged Cafe LS650 Post by DennyzfR6 on 11/21/23 at 14:37:26 The work continues. The shaft for the pulley has been machined. It looks great.. and very solid. Only thing is.. It sticks out of the cover a little too far in my opinion. (forgot to take a picture with the cover installed, will post tomorrow) The cause of the total width has to do with the width/dept needed for the oil seal and the rollerbearing. It also has to do with the width of the pulley itself. There is thicker part in the middle which can be machined down which will take off about 5mm. Plus going to look for a 10mm rollerbearing insteady of the current 15mm. Some of the tolerances could be a little tighter aswell. The goal is to bring the pulley around 10/15 mm inwards. For now, a few pics: http://https://i.postimg.cc/vHJ9C2V6/thumbnail-20231121-203540.jpg http://https://i.postimg.cc/43ZcxKwf/thumbnail-20231121-203544.jpg http://https://i.postimg.cc/zB2H7xNv/thumbnail-20231121-203550.jpg http://https://i.postimg.cc/kX6K1PBm/thumbnail-20231121-180339.jpg http://https://i.postimg.cc/V6kbX332/thumbnail-20231121-205620.jpg |

Title: Re: Supercharged Cafe LS650 Post by DragBikeMike on 11/23/23 at 17:19:12 Denny, When you mention that you are considering a switch from a 15mm bearing to a 10mm bearing, I assume that you are talking about bearing width. Do I have that correct? If I understand correctly, you intend to use a roller bearing. That’s seems like the correct way to go since the left side of the crank must be free to move right & left to accommodate the differences in expansion between the steel crank and aluminum case. The right-hand main bearing also serves as the thrust bearing. It keeps the crank located axially while the left-hand roller bearing allows the crank to move axially. Your additional bearing will need to do the same. Have you put any thought into bearing clearance and how it will work with the stock left-hand roller bearing. The left-hand roller bearing has about .002” clearance by design. You can move the crank up & down about .002”. |
|
Title: Re: Supercharged Cafe LS650 Post by DragBikeMike on 11/23/23 at 17:19:44 But if you move the dial indicator farther from the bearing. The excursion increases to .003”. |
|
Title: Re: Supercharged Cafe LS650 Post by DragBikeMike on 11/23/23 at 17:22:10 Your new bearing will be located even farther from the left-hand main bearing. So, the potential excursion will be even more than .003”. I don’t know if that’s a problem, but it seems like it could be. It would result in the new bearing interfering with the normal up & down play in the left-hand main bearing. It seems to me that would continuously work on the fitup between your extension shaft and the crank. Have you devised a way to check the runout on your extension shaft. It’s impossible to do with the engine fully assembled. As you rotate the engine, the cam drive is pulling on the right side of the crank which causes the left side of the crank to wobble. In addition, the rod is always pulling up or pushing down on the crank as you rotate it. The only way I have been able to get decent runout readings with the crank in the engine is to remove the cylinder head, cylinder, & piston. Then the crank rotates free and you can get half-decent runout readings. I’m curious what sort of runout you have on the end of that extension shaft. When you are all done you will have a three-bearing system and that’s not gonna tolerate much runout, especially with the extension shaft being threaded onto the crank. It might even be preferable to only run a seal on the extension. The seal will tolerate some runout, a roller bearing won’t. How are you planning to lubricate the new bearing. I’ve gone through several left-hand main bearings due to insufficient lubrication. The oil for the left-hand main bearing is provided by the forward cylinder head drain. That drain oil runs down the inside surface of the engine case, so almost none of that oil makes it into the alternator cavity. That cavity runs pretty dry, and any oil that finds it’s way in there gets thrown of by the spinning rotor and flywheel. I don’t think your new bearing will get much oil. You might wanna consider installing an independent oil circuit for that new bearing. This post provides some good info on the oil system. http://suzukisavage.com/cgi-bin/YaBB.pl?num=1695617698 |

Title: Re: Supercharged Cafe LS650 Post by zevenenergie on 11/24/23 at 01:06:03 I like to make a contribution: If the extension of the shaft is turned on an adapter that has the same shape as the crankshaft, you will get a much smaller run out. This adapter must be turned on the lathe and immediately turn the axle on it without removing the adapter, otherwise you will get runout from re-clamping in the chuck. You should use a strong alloy steel for the shaft. You should not underestimate the forces that are placed on the thread. (Using mild steel, don't be surprised if it breaks off.) You would benefit from choosing a sealed C5 bearing to absorb the runout and it does not require oil. It is also important to keep the axle as short as possible. But you have to remain realistic. It's not an ideal situation. Only a seal is a good alternative. And I wouldn't use a v-belt but a toothed belt. And you must ensure that the belt cannot chatter by supporting both parts of the belt with bearings halfway between the pulleys. Then you only absorb the driving forces from the compressor. Your crankshaft bearing will then be subjected to a heavier load. You Should have to calculate whether this remains within limits. You can replace the crankshaft bearing with a cylinder bearing if necessary. I have done this in high reving two stroke engines, and if you do this on one side it works fine. You can get away whit one balbaring to absorb the axial forces. http://i.imgur.com/QH2Jfwkm.png (https://imgur.com/QH2Jfwk) |

Title: Re: Supercharged Cafe LS650 Post by DennyzfR6 on 12/07/23 at 01:11:38 Hi All.. Back again working on the project. Have been busy with a different project here at home.. finally realised a long time dream of having a bike lift at home. It took a lot of work though, so have not worked that much on the Savage. ;D ;D ;D Just have to finish up the electricity etc, final step. Cables already run under the floor just have to hook things up. But really happy and a little proud! :D http://https://i.postimg.cc/nhkY6G1v/20231121-175405.jpg http://https://i.postimg.cc/Kc6NLzzg/20231123-110512.jpg http://https://i.postimg.cc/BnsBYV2S/20231130-155535.jpg http://https://i.postimg.cc/5y3JWrKB/20231130-155030.jpg |

Title: Re: Supercharged Cafe LS650 Post by DennyzfR6 on 12/07/23 at 01:55:41 Soo.. onwards with the bike.. Based on you guys' post we had a good look at the situation regarding the drive.. the extra shaft on the crank and the play etc. We have put the bearing more inwards and closer to the crank. Everything has been moved more inwards quite a bit. We have checked there is enough clearance on the rollerbearing to take up any play.. and I don't think it will be an issue to be honest. In the topic of savagebob he simply pressed a bearing in the cover.. and that also held up, so I think this should definately work. If not.. new cover and we start over :-? It is a bit of an experiment after all ::) Although it is very difficult to do any welding on the cover due to the material, welding has gone well.. everything has been centered and it all fits perfectly. No warping.. The extention shaft is made of hard steel. It has to be altered and shortened for the new dimension of the bearing and bushing etc.. Will have to be done by a machining expert.. so again have to wait for this. For lubrication I am hoping there is enough splashing around so that the bearing will at least receive some. Savagebob had issues with oil leaking through his pressed in bearing so there should at least be some oil being thrown around in there. Honestly, I don't even want to think about setting up a seperate oil system just for that bearing. I did read through the enitre topic of DragBikeMike on the oil system. It is a shame it is so much work to do that type of upgrade.. :-/ I would feel more comfortable with an extra oil cooler on the bike. But maybe down the line... will think about it. It will also look nice to have something like that connected.. and should help the bike. Also with the way the exhaust is routed. I am not aiming for any maximum power gains though.. although more than stock is definately expected. Ow, and thanks everyone for your inputs! :) :) Some more pictures: http://https://i.postimg.cc/nhJFrKYX/Afbeelding-van-Whats-App-op-2023-11-28-om-12-38-49-533b5d0f.jpg http://https://i.postimg.cc/hPx4KZxF/Afbeelding-van-Whats-App-op-2023-11-28-om-12-38-49-017e1f72.jpg http://https://i.postimg.cc/QNvxGZFk/Afbeelding-van-Whats-App-op-2023-11-28-om-12-38-49-ac0783a4.jpg http://https://i.postimg.cc/FKYdDyCF/Afbeelding-van-Whats-App-op-2023-11-28-om-18-52-35-9f391ba9.jpg http://https://i.postimg.cc/k5LVZ2LQ/Afbeelding-van-Whats-App-op-2023-11-28-om-18-52-35-5a41bf00.jpg http://https://i.postimg.cc/KzLKyZyd/Afbeelding-van-Whats-App-op-2023-11-28-om-18-52-33-13730d14.jpg Here the bearing used for welding is in, this will be replaced with a fresh one: http://https://i.postimg.cc/CKc7fsBF/20231204-105112.jpg |

Title: Re: Supercharged Cafe LS650 Post by DennyzfR6 on 12/07/23 at 02:39:14 For inspiration on what to do with the tank and the seat and to take measurements for fabrication, I put my current ones on the bike. It is a Savage tank in which I already filled the hole a few years back so it is pretty clean. And it's the Ryca seat unit. Both will not be used on this bike.. so as I stated before, might have to build another more typical Ryca cafe down the line with all the leftover parts. The goal for this one is to build a tank and seat unit out of 1 piece. All aluminium. Part of it will be painted, and part will be polished. That's the idea. As so much fabrication is being done under the tank/seat unit, the goal is to be able to pivot the whole unit upwards from the rear, keeping it up with a (hidden) gas spring. The exhaust will go underneath the seat down the middle and the rear light will be build into the rear seat unit with the same design as the exhaust tip. We are still a long way away from that, but for now: http://https://i.postimg.cc/N0Bk0Hpn/20231114-170808.jpg http://https://i.postimg.cc/bNSTV8Zm/20231114-171607.jpg |

Title: Re: Supercharged Cafe LS650 Post by DennyzfR6 on 12/08/23 at 11:58:26 Finally.. it is exhaust time! To make it look a little different than most Savages.. and to have it flow nice with the lines of the bike, the idea is to bring it to the left side of the bike. Also because the sidestand will be moved to the right. Have the exhaust follow the shape of the cilinder, then the line of the left stator cover and then move it back to the the middle of the bike. Move it up between the vertical rear of the frame just in front of the rear wheel en then have the tip come out of the rear seat. With that in mind, mocking up the lines are the first step: http://https://i.postimg.cc/VLwtmbv4/Afbeelding-van-Whats-App-op-2023-12-05-om-14-28-15-5ece621b.jpg http://https://i.postimg.cc/KYWL2q3g/Afbeelding-van-Whats-App-op-2023-12-05-om-14-28-28-3e8332a1.jpg http://https://i.postimg.cc/GmqGMhcK/Afbeelding-van-Whats-App-op-2023-12-05-om-14-28-37-50de6413.jpg http://https://i.postimg.cc/FF3SMxr7/Afbeelding-van-Whats-App-op-2023-12-05-om-16-59-49-305e9a1d.jpg |

Title: Re: Supercharged Cafe LS650 Post by DennyzfR6 on 12/08/23 at 12:09:25 Then it was time to start making segments.. Whilest doing this decided to give the cilinder a little more distance from the exhaust to hopefully provide a bit better cooling. I understand the current setup is not optimal in that regard.. Might get the exhaust coated in the inside.. to hopefully deflect a little more heat. Will have to look into this. Also, segments will be added later with springs for disassembly and heat expansion once everything is in place. http://https://i.postimg.cc/TPNjP2F1/Afbeelding-van-Whats-App-op-2023-12-05-om-17-15-01-78b239cb.jpg http://https://i.postimg.cc/RV1cHLyj/Afbeelding-van-Whats-App-op-2023-12-05-om-17-14-47-1eda2d9a.jpg http://https://i.postimg.cc/28NQyKcQ/Afbeelding-van-Whats-App-op-2023-12-05-om-17-14-54-c36ec8ca.jpg http://https://i.postimg.cc/cJLMZtDP/Afbeelding-van-Whats-App-op-2023-12-05-om-17-15-29-66523ec1.jpg http://https://i.postimg.cc/L5LjvtXg/Afbeelding-van-Whats-App-op-2023-12-06-om-13-33-02-e41f3761.jpg And then finally :) ...: http://https://i.postimg.cc/QtRpp4Xr/Afbeelding-van-Whats-App-op-2023-12-06-om-17-21-49-474b4d87.jpg |

Title: Re: Supercharged Cafe LS650 Post by DennyzfR6 on 01/24/24 at 05:10:42 We're back. End of the year has been very busy.. . Holiday season, other projects etc. Making good use of the bike lift at home.. which is fully finished now aswel ;D http://https://i.postimg.cc/g2PbCR1H/Afbeelding-van-Whats-App-op-2024-01-24-om-13-20-05-e19c5456.jpg PS. Don't worry about the front wheel clamp. That is secured and cannot slide off. It has a locking pin in place. ;) The work on the Supercharged Savage is also underway again. Firstly, some decisions had to be made, mostly around the exhaust. First, the points where to place the exhaust springs for easy disassembly. Because of the intricate bends the first one needs to be close to the head, so that has been fabricated. http://https://i.postimg.cc/sf08rSGZ/20240123-152855.jpg http://https://i.postimg.cc/sx1NWfqX/20240123-152956.jpg The next big decision is how to run the exhaust after it 'wrapped' around the cilinder. Also, taking into account the position of the belts and tensioners for the supercharger. We took some measurements whilst sitting on the bike to see where my legs will go. This was also necessary for the rearset and the start of the fabrication of the seat etc. If it would simply run straight this would be it: http://https://i.postimg.cc/pdZG1ntr/Afbeelding-van-Whats-App-op-2024-01-24-om-13-14-33-540360db.jpg It looks clean in parallel with the charger and the frame etc, but it would make other things very difficult as it leaves very little room voor brackets and support for the pulleys and everything will have to be worked around the exhaust. The belt will have to jump inwards to the center of the bike excatly where the exhaust would sit. http://https://i.postimg.cc/jdpFWbXx/Afbeelding-van-Whats-App-op-2024-01-24-om-13-32-40-063bee69.jpg So after some more brainstorming and measurements: http://https://i.postimg.cc/652P53Cb/Afbeelding-van-Whats-App-op-2024-01-24-om-13-35-17-90147924.jpg http://https://i.postimg.cc/vZ5SfNqW/Afbeelding-van-Whats-App-op-2024-01-24-om-13-35-50-a0cfeab2.jpg The shape has been determined and will roughly be the following :) : It will leave room in the middle, also aesthetically and will make it easier to fabricate and place al the brackets etc for the transfer inwards, the pulleys and tensioners. http://https://i.postimg.cc/s2yHc4qb/Afbeelding-van-Whats-App-op-2024-01-24-om-13-06-10-82ae5029.jpg Back to puzzling with cutting and welding! ;D |

Title: Re: Supercharged Cafe LS650 Post by zevenenergie on 02/08/24 at 02:34:57 Eye Candy.... I think it's cool how you're working on all those ideas. I also like to tinker and experiment. But it is striking to me that you increase the power through a compressor and have narrowed the belt.(I must say that it looks very attractive) I understand that exhaust, and it's nice that it takes a different route than normal. But don't get bogged down in too much detail. I would rather use that time to lower the compression so that you can store more mixture in the combustion chamber. And to install such a DR coupling as Drag bike Mike designed. I would think it would be very cool if this block produced a lot of power and that you could transfer it to the asphalt. And if that's the case, I'll come and check on you and copy everything you done. So get your stomach wet. For everyone here, that,s a Dutch expression (Denny is also frome the Netherlands) I'm proud of you danny. [smiley=thumbsup.gif] |

Title: Re: Supercharged Cafe LS650 Post by DragBikeMike on 02/08/24 at 12:22:33 Denny, are you going to place an intermediate shaft between the drive pulley and the blower pulley? Is that how you plan to account for the misalignment between the two pulleys? Seems like that could also provide some additional options for drive speed. Your frame is awfully long between the top motor mount and the shock mounts. There is no triangulation across that span. If you hang the blower off the frame, won't it place a lot of stress at the connection between the cylinder head and the intake reservoir? Could you use a felxible connection instead? |

Title: Re: Supercharged Cafe LS650 Post by ohiomoto on 02/08/24 at 12:50:21 I also question the lack of triangulation. I think the lower motor mounts should help stabilize the swing arm pivot, but the spine is pretty long. But I'm not an engineer and Danny might be planning something after he gets the details of the supercharger and exhaust worked out. |

Thanks fellow dutchman! yes, a lot of time is being spent on the details.. but... that is precisely the point of the bike to be honest. ::) To be bit of a showpeace.. performance honestly is not that important to me. It will be nice if it makes some boost but my goal is not to push anything tbh. There are much easier, and far cheaper ways.. to move more quickly on 2 wheels than customizing a Savage :D What is that DR coupling of Drag Bike Mike you are referring to? |

You guys are correct, on both points. Additional frame strengthening is on the agenda, and will be done once all of the exhaust is in place, and the bracketing is in place. Looking into either combining it into the necessary brackets, or placing it afterwards An intermediate shaft will also be placed. Currenyl trying design a tensioner that can do the job for both pulleys in 1 adjustment to minimalise everything. Will update once the idea has been worked out a bit further. ;D |

Title: Re: Supercharged Cafe LS650 Post by DennyzfR6 on 02/11/24 at 09:30:27 Final steps on the exhaust: http://https://i.postimg.cc/GhtLpXXf/Afbeelding-van-Whats-App-op-2024-02-09-om-14-54-17-71c937ea.jpg Making sure everything is centered: http://https://i.postimg.cc/J7P7mf5J/Afbeelding-van-Whats-App-op-2024-02-09-om-14-54-16-88b39f86.jpg http://https://i.postimg.cc/76z0Ggqv/Afbeelding-van-Whats-App-op-2024-02-09-om-15-28-03-73aca15f.jpg http://https://i.postimg.cc/nrcHB2pC/Afbeelding-van-Whats-App-op-2024-02-09-om-15-27-50-6ef83e9f.jpg Last thing to do is the final section. It needs to follow the arc that is in the frame plates and alligns with the rear wheel. So some drawings need to be made.. but we are almost there. Also another section with exhaust springs will be placed in the section between the frame. And currently in the proces of designing the mounts on how to support the exhaust on the frame. I think it will look pretty good tbh ;D 8-) http://https://i.postimg.cc/PqYrjNSr/Afbeelding-van-Whats-App-op-2024-02-09-om-17-50-24-70c502b3.jpg |

Title: Re: Supercharged Cafe LS650 Post by DennyzfR6 on 02/11/24 at 09:33:49 Also, the extension shaft for the pulley has been shortened, it looks much cleaner now: http://https://i.postimg.cc/XvvNZ3c9/Afbeelding-van-Whats-App-op-2024-02-09-om-15-15-15-fd331a00.jpg And everything has been checked and measured and level. It is now ready for mounting it to the frame. http://https://i.postimg.cc/XJWN73PK/Afbeelding-van-Whats-App-op-2024-02-09-om-15-26-54-6cbb4e5d.jpg http://https://i.postimg.cc/XJWN73PK/Afbeelding-van-Whats-App-op-2024-02-09-om-15-26-54-6cbb4e5d.jpg to be continued! |

Title: Re: Supercharged Cafe LS650 Post by Michael Moore on 05/07/24 at 16:20:00 You are doing some nice work! Isn't it fun to build a tucked-away high pipe? :) You've had to do a lot more work than I did for the 2->1 exhaust on my Laverda 750 racer, but I did enough work that I made sure that the next two frames that I built were able to use the exhaust without modification. The SF2 engine is a big lump to work around. :) https://motoconstructor.com/graphics/Laverda/LavSF2RRMK1001a3.jpg cheers, Michael |
