Title: Free bike; engine rebuild!!!!? Post by sillydilly on 04/11/11 at 23:35:46 Hey guys, pleased to say my neighbor (we'll call him Dustin to protect honor) scored a free torn apart 1986 Savage from someone who was going to toss it. 33,000km, and everything organizingly dismantled. http://img849.imageshack.us/img849/4514/sany2314.jpg However after 8 years of this bike sitting neatly in boxes, it ended up in the back of Dustins truck and later on his driveway where it collected sawdust from his garage. Long story short we were going to part it out but I decided to give it a go and see what I can do for my very first engine job. http://img132.imageshack.us/img132/4733/sany2312.jpg Im only at the engine right now. First thing I did was a mockup assembly, guessing where parts go, just to see if I might be missing something major. Seems to be all there. http://img535.imageshack.us/img535/3040/sany2323.jpg I took it apart and cleaned out most of the sawdust and other junk. Bought some Ultra Black just to get a decent oil seal while I dump some oil in it, set the valves, and check for compression. http://img543.imageshack.us/img543/8839/sany2319.jpg I basically finished it up, with a few leftover parts :-X http://img717.imageshack.us/img717/3508/sany2326.jpg Now I better ask some questions... 1) I used regular gasket paper + Ultra Black for the head gasket, was told it wont hold up, but for research purposes Im going to try it. 2) How can I crank the started directly off a batter/charger? Dont feel like mounting it into the bike or hand cranking with a socket anymore. 3) when setting the timing chain, I marked the white line on the flywheel at the 3 o'clock position through the cap checker thing for TDC. Then I lined up the cam markings with the block, lobes facing down, and mounted the chain, secured everything, dabs of grease and oil everywhere. Attempted to set the valves, everything seems to be functioning smoothly. Did I do this properly? 4) Can anyone Identify these extra parts :D http://img25.imageshack.us/img25/1149/sany2325.jpg |

Title: Re: Free bike; engine rebuild!!!!? Post by verslagen1 on 04/12/11 at 00:14:27 You need a new cam chain, that one is pretty stretched. if that plunger falls out you'll be looking for a shovel and a trash can. Yeah, paper and rtv won't last long on the head. probably better off reusing the old one. There's a bolt sticking out of the starter, that's positive. If it stalls, rotate the crank a half turn forward past compression TDC then go at it again. L to R a spacer, an o-ring, a bolt, a bolt, and a pin. all of them can go any where you see a hole. The pin goes in the center of the clutch. Hey, I'm not complaining, you got it free and it lives. [smiley=thumbsup.gif] |

Title: Re: Free bike; engine rebuild!!!!? Post by justin_o_guy2 on 04/12/11 at 02:56:48 I havent been thru every nook & crannie on the bike, buy Im not really thinking the spacer & O ring are part of the bike. Yea, that sre looks like the clutch throwout pin,,& the bolts,, well, Id be looking up top of the engine for the long one, short one?? No clue. Congrats on getting this far. |

Title: Re: Free bike; engine rebuild!!!!? Post by splash07 on 04/12/11 at 08:19:57 Looks like the previous owner was familiar with the cam chain tensioner weaknesses and made his own verslavy. |
|
Title: Re: Free bike; engine rebuild!!!!? Post by buttgoat1 on 04/12/11 at 09:06:58 you did very well considering all you had was a box of parts to start with. as far as the cam chain, how about a safety wire to keep it from falling out, at least just for demo purposes. |

That was me, Im assuming thats why he tore it apart is because of a rattle. I had known about this issue from this forum with a previous bike I had visited with. Assuming all the Gasket maker has cured this morning, gunna torque everything up and run some oil through it, crank it over, get soome of that sawdust moving, see if we get compression. |

Title: Re: Free bike; engine rebuild!!!!? Post by sillydilly on 04/12/11 at 15:07:06 having a bit of problems with the clutch now that the pins in. I pull up on the clutch lever on the clutchcase when its on and it wont budge. any ideas? should I be tightening the 4 springbolts all the way in? http://i291.photobucket.com/albums/ll291/thetoolswingguy/Cruisers_GZLSTUVSVXVZVZRVLGV_LS650-.png I also only seem to have only 10, or 11. not both??? |
|
Title: Re: Free bike; engine rebuild!!!!? Post by verslagen1 on 04/12/11 at 15:25:46 I'll have to look to see again, but think 10 is flat and 11 is beveled. the 4 bolts should be tightened all the way down. |
|
Title: Re: Free bike; engine rebuild!!!!? Post by sillydilly on 04/12/11 at 17:36:29 alright, im leaving the clutch out until further notice. Just mounted the engine, connected all the wires, and put a batter charger on the positive battery wire + grounded. all the lights come on and everything works, until you put the right hand engine switch to "Run", then I get a constant, loud, arch between the plug and the block. http://img705.imageshack.us/img705/8557/sany2334.jpg I wanna tinker, but it sounds PAINFUl |
|
Title: Re: Free bike; engine rebuild!!!!? Post by verslagen1 on 04/12/11 at 17:43:58 don't leave that on for very long, it'll burn out your coil. |
|
Title: Re: Free bike; engine rebuild!!!!? Post by verslagen1 on 04/12/11 at 17:46:12 One side of the coil is hot, the other goes to ground thru the CDI. So you got a short on that wire. |
|
Title: Re: Free bike; engine rebuild!!!!? Post by sillydilly on 04/12/11 at 18:23:06 decided to just put the battery charger onto the starter and it looked like it was sparking accordingly. I couldnt wait any longer. 4 days after hovering over this engine I needed to see it TRY and run. Ran down and got some gas, put it together half assed, fired her up! It sounds like the timings off, can anyone diagnose this? http://www.youtube.com/watch?v=59_g3MTc_zE then I tried again directly to battery, and voila fired up a lot better than before, but really bad still. vid coming in 10 mins |

Title: Re: Free bike; engine rebuild!!!!? Post by verslagen1 on 04/12/11 at 18:59:05 The savage is really voltage sensitive. A low battery will make it miss and pop. |

Title: Re: Free bike; engine rebuild!!!!? Post by sillydilly on 04/12/11 at 20:23:52 you're right, 10 was hiding there. so here's the problem. Its all assembled, but the clutch thing still wont budge. ill snap some quick pics |

Title: Re: Free bike; engine rebuild!!!!? Post by verslagen1 on 04/12/11 at 20:58:54 Also the bevel washer, the inside should be the high side. |

Title: Re: Free bike; engine rebuild!!!!? Post by sillydilly on 04/12/11 at 21:33:09 we got her!! Turns out it was the bevelled plate backwards, and the special plate was on the back not the front. why isnt this in the clymer?? thank you sooo much for your help!!! |

Title: Re: Free bike; engine rebuild!!!!? Post by sillydilly on 04/12/11 at 21:38:44 while you're still here, can you try and see if you can diagnose whats wrong with the way she runs? http://www.youtube.com/watch?v=zejrPR0eqOk Keep in mind I dont have proper gaskets, everythings kind of finger tightened, and theres no battery just direct charger > batter wires something like valves or timing? |

That o-ring probably goes on the oil filter, see part #10 in this schematic: http://www.bikebandit.com/2009-suzuki-ls650-crankcase/o/m18184sch595413#sch595406 Good project you got there :) |
|
Title: Re: Free bike; engine rebuild!!!!? Post by verslagen1 on 04/12/11 at 21:48:46 ya gotta whistle, header or muff clamp loose. I thinking you don't have the cam timed right. with that really stretched chain it ain't gonna look right. With the crank at TDC, on the straight side of the chain, the cam mark will be high. This will cause the popping out the carb. |
|
Title: Re: Free bike; engine rebuild!!!!? Post by sillydilly on 04/12/11 at 22:05:34 Im pretty sure that 10 o-ring was already on the filter, this one is much larger. Vers, you're absolutely correct. http://img709.imageshack.us/img709/5713/sany2364i.jpg http://img199.imageshack.us/img199/817/sany2363t.jpg without buying a new chain, how do I correct this? |
|
Title: Re: Free bike; engine rebuild!!!!? Post by sillydilly on 04/12/11 at 22:20:00 vers, I wanna add something. you've mentioned my really loose cam chain before; and I just checked first page, and therese a picture of a mock of your mod. That's without the cam gear up top, so its sagging a lot giving the appearance its touching. heres a more accurate picture showing its position. http://img600.imageshack.us/img600/719/sany2357.jpg |
|
Title: Re: Free bike; engine rebuild!!!!? Post by verslagen1 on 04/12/11 at 22:34:15 Good, your cam chain looks normal for a 2 holer. and the cam orientation looks right. Ok, on to other newbie pit falls. Valve adjustment, there are 2 tdc's, adjust the valves on the tdc on the compression stroke. Take both inspection covers off, rotate the crank the same way the wheels turn forward. watch for the intake valves to up and down then another half turn and align the tdc marks on the crank. |
|
Title: Re: Free bike; engine rebuild!!!!? Post by sillydilly on 04/12/11 at 22:39:30 lobes up or down? |
|
Title: Re: Free bike; engine rebuild!!!!? Post by verslagen1 on 04/12/11 at 22:42:48 idk, never looked at them. follow directions, can't go wrong. |
|
Title: Re: Free bike; engine rebuild!!!!? Post by sillydilly on 04/12/11 at 22:52:41 morning project, already shut her down for the night, got the clutch case gasket curing. thanks for all the help tonight and Im sure Ill throw a handful more questions tomorrow! |
|
Title: Re: Free bike; engine rebuild!!!!? Post by BurnPgh on 04/13/11 at 03:46:20 lobes down |
|
Title: Re: Free bike; engine rebuild!!!!? Post by sillydilly on 04/13/11 at 09:23:28 can anyone tell me intake and exhaust specs? I know its 0003-0.005... but is that 0.003 TO 0.005 = acceptable or intake = 0.003 exhaust = 0.005 ?? [edit] ok so I did some fiddling and I think I did it right. I cannot get a 0.005 in the valves, and 0.004 is tricky, and the 0.003 will slide in. did I do it correct? Im also down to 100 psi now... |
|
Title: Re: Free bike; engine rebuild!!!!? Post by sillydilly on 04/13/11 at 10:44:55 Im positive I had 150psi yesterday, why would I be down to 100 now? |
|
Title: Re: Free bike; engine rebuild!!!!? Post by babyhog on 04/13/11 at 11:12:12 I know nothing about rebuilding an engine, but I sure like pictures. LOL Seriously though, looks like an awesome project. I've been here quite a while and still get amazed at the extent of knowledge of our members. Impressive stuff. Oh, and I see you have one special required tool on hand. Beer! ;D |
|
Title: Re: Free bike; engine rebuild!!!!? Post by sillydilly on 04/13/11 at 11:40:18 thanks! Im gunna start a new thread, this ones just a little everywhere. |
|
Title: Re: Free bike; engine rebuild!!!!? Post by verslagen1 on 04/13/11 at 11:50:19 No need to start a new thread, no matter what you do it will go all over. and you loose history so you need to explain yourself all over again. 100 psi? not good, 150 psi ok. You want both valve (left and right) to have the same clearance. Intake and exhaust can be different. |
|
Title: Re: Free bike; engine rebuild!!!!? Post by sillydilly on 04/13/11 at 12:07:33 as far as I can tell you they are all close to being the same. how would I have lost compression? valves?? Im uploading a video demonstrating how it just finished running. It seems like it will crank over then when it dies, the crank does a 1/4 revolution the wrong way and spins the starter motor backwards. Im guessing this is timing? but in my previous pictures I showed you said I did it right?? |

Title: Re: Free bike; engine rebuild!!!!? Post by sillydilly on 04/13/11 at 14:07:05 what are the odds of it being plug/carb related??? |
|
Title: Re: Free bike; engine rebuild!!!!? Post by sillydilly on 04/13/11 at 15:03:05 Sprayed some carb cleaner in her and she ran a LITTLE bit better. |

Title: Re: Free bike; engine rebuild!!!!? Post by sillydilly on 04/13/11 at 20:57:39 CAM UPSIDE DOWN? TIMINGS 180DEGREE OFF? ANYONE?? |

Title: Re: Free bike; engine rebuild!!!!? Post by verslagen1 on 04/13/11 at 21:07:55 Your pic's... http://img709.imageshack.us/img709/5713/sany2364i.jpg http://img199.imageshack.us/img199/817/sany2363t.jpg From Oldfellers thread... http://suzukisavage.com/cgi-bin/YaBB.pl?num=1256079122 http://www.hunt101.com/data/500/medium/cam_line_up.JPG So yes, you installed it upside down, sorry I didn't notice it earlier. |
|
Title: Re: Free bike; engine rebuild!!!!? Post by sillydilly on 04/13/11 at 22:33:24 >_< well I think we're both wrong. We skipped a toooth on the timing chain now now matter what TDC is it lines up perfectly. If that doesnt do it, we'll flip the cam 180 degrees. |
|
Title: Re: Free bike; engine rebuild!!!!? Post by sillydilly on 04/13/11 at 22:35:55 unless i was both 1 tooth off AND upside down?? gunna give it a go really quick, getting good at pulling the engine on these |
|
Title: Re: Free bike; engine rebuild!!!!? Post by verslagen1 on 04/13/11 at 22:37:14 always turn the engine over by hand to check for interference. |
|
Title: Re: Free bike; engine rebuild!!!!? Post by sillydilly on 04/13/11 at 22:39:09 what sort of interference? |

Title: Re: Free bike; engine rebuild!!!!? Post by sillydilly on 04/13/11 at 23:14:56 I think we're at true TDC right now and the orientation of that gear is opposite, dowels on other side.... but she runs a lot better than beefore, just backfires like crazy! I was told you can just take something near the magneto and flip it 180 degrees to correct this? or cam flip? |
|
Title: Re: Free bike; engine rebuild!!!!? Post by sillydilly on 04/13/11 at 23:17:44 how about rather than pulling engine, just popping off clutch cover and swapping that bottom gear 180? or is it 360?? |
|
Title: Re: Free bike; engine rebuild!!!!? Post by verslagen1 on 04/13/11 at 23:31:21 I don't know who told you that crap, been here a long time, never heard it before. I'm surprised 180° out of time didn't end it for you. You can take the head cover off in the frame... do it right. |
|
Title: Re: Free bike; engine rebuild!!!!? Post by sillydilly on 04/14/11 at 00:09:01 just fired it up, this is the best its ever ran. it will idle, unconsistantly, little hesitation and some missing. Give her full throttle and she pops and bangs but will keep on running... you were right about the cam!!! any idea why its still popping? running lean? no air filter? valves? head gasket? ill do a vid for you tomorrow |
|
Title: Re: Free bike; engine rebuild!!!!? Post by verslagen1 on 04/14/11 at 00:32:31 no air filter? lean air box open? way leaner little hesitation, maybe a sticky slide in the carb, seafoam or clean the carb, becareful of finger prints on the slide. |
|
Title: Re: Free bike; engine rebuild!!!!? Post by justin_o_guy2 on 04/14/11 at 01:54:48 Im still tryin to understand ho it would be so bad..seems it would make the TDC comp/exhaust swap places ..

|
Title: Re: Free bike; engine rebuild!!!!? Post by sillydilly on 04/14/11 at 10:28:31 Im gunna put it back together properly, with all the breather tubes, air filter, etc. then run some seafoam through her and some carb clean |

Title: Re: Free bike; engine rebuild!!!!? Post by sillydilly on 04/14/11 at 11:41:29 http://www.youtube.com/watch?v=Bia3oMPkmdk got a wicked valve tick but it runs awesome. even took her for a burn up and down the street before I got scared it would fall apart. |

|
Title: Re: Free bike; engine rebuild!!!!? Post by spacepirates on 04/14/11 at 12:35:00 I can take care of some of the easier ones: The two matching bolts (second and third from the left) go inside the two black rubber mounts (forth and fifth from the left) which in turn goes atop the black tab (second from right) which bolts through the tab on the bottom of the tank into the frame. The other black tab (third from the right) goes on the side of the battery box and is part of the locking mechanism for the tool box cover. as for the rest... no clue. frame bolts maybe? the two bolts with the rounded heads might go on the foot controls. |
|
Title: Re: Free bike; engine rebuild!!!!? Post by splash07 on 04/14/11 at 12:44:36 The two bolts with the rounded heads (8th and 9th from left) are header bolts that go through the flange and mount to the block. The bolts (12th and 13th from the left) look like motor mount bolts, the ones that mount through the frame and thread into the exhaust bracket. The very first bolt also appears to be a motor mount but I am not 100% sure. |
|
Title: Re: Free bike; engine rebuild!!!!? Post by sillydilly on 04/14/11 at 12:44:46 that takes care of a lot. im guessing soem of it, like that huge belt, was just tossed into the box from a 3rd party source over the years. |

Title: Re: Free bike; engine rebuild!!!!? Post by splash07 on 04/14/11 at 12:47:04 That's a pretty good looking bike for the price of FREE! |

Title: Re: Free bike; engine rebuild!!!!? Post by OE on 04/14/11 at 13:33:56 The third one from the right is the bracket that a key latch in the lower side of the toolbox cover locks into. I'm not so sure about those 2 black bushing looking things 2nd & 3rd from the left. The bushings that go on the gas tank hold down part (2nd from the right) on my bike are in 2 parts each with an insert in them. Those look like they are one piece each and look too big to me. The big belt looks like a strap that's used to carry a post type battery. Just slip the openings over the posts and they kinda jam into the lead posts when you pick it up. For $200 buck you really got a deal and a pretty good education to boot. |

Title: Re: Free bike; engine rebuild!!!!? Post by sillydilly on 04/14/11 at 14:05:41 like I said it was my very first engine and I was just gunna part it out. ended up mocking up the engine and putting some time into it, only to find out it runs nicely. Cheap bike, learned a ton, and having a lot of fun. Im gunna try and fit these mix and match pieces on eventually! |

Title: Re: Free bike; engine rebuild!!!!? Post by verslagen1 on 04/14/11 at 16:07:01 I'll bat clean up... (BTW you guys did good) 1. The very first bolt also appears to be a motor mount but I am not 100% sure. Think it goes on the back by the oil window 2&3. The two matching bolts go inside 4&5. Tank mount 4&5. two black rubber mounts which in turn goes atop the black tab (18) Should split apart and sandwich 18. tank mount 6. rubber spacer for chrome head cover 7. washer for 11 8&9. The two bolts with the rounded heads are header bolts that go through the flange and mount to the block. 10. sh!tsky 11. spacer for pulley cover 12&13.

Title: Re: Free bike; engine rebuild!!!!? Post by Southpaw on 04/14/11 at 16:35:41 The last piece on the right flips over and bolts behind the tank to hold the front tab of the rider's seat in place. The belt thing at the bottom appears to be an old style auto battery carrier where the holes go over the battery posts and get jammed tight by the aluminum tabs just below them. |

Title: Re: Free bike; engine rebuild!!!!? Post by sillydilly on 04/15/11 at 15:28:14 Ok so Ive put it mostly back together and got it running. Fresh fuel, fresh plug, still a bit of problems. It will run and idle, pretty nicely, but it misses sometimes. Also, i took it for a ride, and when I floor it, it will rev up slightly, then start bucking. Im wondering if the engines good now, I need to hit the carb? |

Title: Re: Free bike; engine rebuild!!!!? Post by sillydilly on 04/15/11 at 16:13:46 wide open throttle. with choke on, it will generally slowly rev high without much backfiring or problems. choke off she pops a bit |

I found that the factory service manual is much better when working on the engine. But yours is together so that's a after thought. The parts manual I made and is posted in the tech ref section is extremely handy when piecing it back together. Have you cleaned the carb? It may be really gummed up from sitting. Having to run on choke is one of the signs. Usually means the low speed jet is dirty. Did you replace the plug? I thought I saw in one of the pages but don't feel like reading thru them again.

Title: Re: Free bike; engine rebuild!!!!? Post by sillydilly on 04/16/11 at 16:37:07 I cant recall. I put new plug and new fuel in there, new air filter, valves are a bit off, but otherwise 120psi and timed correctly. When I tore the carb apart, it was surprisingly clean except for a really sticky residue at the bottom of the bowl and a little on the floats. I soaked everything in Lacquer thinner then reassembled it. the whole process took about 20 minutes. I think I'll attack it again and spend more time cleaning out the parts, then Ill post a plug-reading to maybe see whats goin on |
