Title: Louder exhaust sound Post by walkingscar1943 on 04/26/12 at 09:20:24 Cheers all, A question for you techies. Is it possible to sweeten the exhaust note on my 2009? I do not care for loud sounds but a little louder than stock would be ok. Also can this be done without changing carb or air intakes? I think the one lunger might sound nice. Walkingscar |

Title: Re: Louder exhaust sound Post by justin_o_guy2 on 04/26/12 at 09:24:42 You could drill some holes in the back end of that barge they call a muffler, or, drop $20.00 & stick a Dyna muffler on it, mellow sound, deeper, throatier sound, most likely require rejetting, either way, |
|
Title: Re: Louder exhaust sound Post by verslagen1 on 04/26/12 at 09:39:46 stock bikes are jetted lean to begin with. openning up the muffler make it leaner. get a jet kit from lancer and read up on carb tuning in the tech section. Then go for it. either a little ventilating with a drill, dyna muff or hartman mod will provide a better sound. |

Title: Re: Louder exhaust sound Post by Serowbot on 04/26/12 at 09:56:52 If you live above 3k ft... it might not need a rejet, less than that and you probably will... This is not a carb change... just slightly bigger jets... Very easy to do, and cost about $10... Just don't open up too much... this bike will get loud very easily... Too open, and you'll be setting off car alarms for blocks... :-?... Harley take-off mufflers do a great job without drilling holes. and they're cheap... |

Title: Re: Louder exhaust sound Post by teabowl13 on 04/26/12 at 12:43:08 You could check out the ones that the RYCA guys are using too; several of those guys have complained that they are too loud, but if that floats yer boat.... They are made by EMGO, and any of their slip-on mufflers will work as long as they have the right inlet size for the header; I know MOTOBUDDAH flirted with a different style of emgo pipe. Supertrapp also makes a few different models that will fit; again, find out the pipe size that you need to connect to and search that way; if you just look for LS650, or Savage, or S40 you won't find as much... I got mine for free from my buddy Jay!! No idea what it is, but it looks awesome... bet it's going to be really loud too, so I'm thinking it'll need some extra baffling inside to calm it down. http://p1.bikepics.com/2012/03/13/bikepics-2364558-full.jpg If you are changing the exhaust and re-jetting it might be a good time to switch to a pod filter to take full advantage of the extra power you can get. There are tons of folks who have done these mods in the tech section, so everything you need is there to find if you just search a little bit... |

Title: Re: Louder exhaust sound Post by WD on 04/26/12 at 15:59:47 If you buy an Emgo or Motoasia muffler, expect to be disappointed... Unless you really like flaming wads of rusty packing and baffling flying out the back of your bike. If you like the look of the cheapy mufflers, gut them and repack with something decent. I run an empty 12" glasspack into a 29" fishtail pipe, which has a real baffle stuck in the end. I think a 12" baffle. And a handful of copper dish scouring pads tossed in to kind of calm things down. Best sound for a Savage? Turn down exhaust tip where the muffler used to be. Sounds like a Chinook helicopter, Emgo mufflers it sounds like a Huey. Turn down tip will blow holes in your yard on shutdown. That's how I used to get rid of fire ant nests... |

Title: Re: Louder exhaust sound Post by mayor4u on 04/27/12 at 09:08:58 I found that if you look at the back of the stock muffler, you'll notice 4 pop rivets seemingly to hold the baffle assembly in, if you drill those out and open them up with a large unibit, approx 1/2 " ( be sure to take a magnet and get ALL the shavings out) it provides better breathing, a nice throaty sound and you can still maintain the great looks of the stock unit, and it seems its not enough difference air to fuel wise to require different jetting [smiley=thumbsup.gif] |

Title: Re: Louder exhaust sound Post by Nskawtea on 04/29/12 at 08:58:33 Routy I did the same thing after looking around this site and I'm happy I drilled then. More throaty sound. Like a Suzuki sv650 with a modded exhaust when I let off the gas :D |

Title: Re: Louder exhaust sound Post by Jacob on 04/29/12 at 19:07:52 I am about to do the drilling mod this week to my 2012 S40. Anybody recommend the (8) 5/16" drilled holes or the 4 1/2" drilled holes. I noticed a few people had the (8) 5/16" holes and really liked it with no jetting and that is kind of where I am leading! I am out for a little louder exhaust. Nothing extremely loud! |
|
Title: Re: Louder exhaust sound Post by Nskawtea on 04/29/12 at 21:44:38 The (8) 5/16 should be just fine. Just duplicate the other guys picture and you'll get a very nice sound. The sound is louder and throaty but not loud enough to get you pulled over |
|
Title: Re: Louder exhaust sound Post by justin_o_guy2 on 04/29/12 at 21:56:50 Drilling a 1/2 hole takes a lot more Ooomph than a 5/16ths, 8 small holes would look better than 4 fat ones, IMO, & you may run into something inside that jams up the bigger bit, we can see a pic of a very successful job. Id do it that way. 4X1/2"= .7854 square inches 8X5/16" = .6136 Or maybe Im not gettin that rite,, |

Title: Re: Louder exhaust sound Post by Jacob on 05/01/12 at 17:29:20 Routy Could you post the link or url to the posting of the white spacer mod that you did? I looked for it but was not successful. I'd just like to see how it is done so I can eventually do it. Is it all instructions telling you how to do it or is it pictures and instructions. Anyways if you could help me, I'd be a happy camper. I ended up putting 4 5/16" holes in the end plate baffle and will be adding four more tomorrow after work. Just in the same order as you. I also ordered a powerstar spark plug tonight. Going to try that out also. Thank you. Jacob |

Title: Re: Louder exhaust sound Post by Routy on 05/02/12 at 05:39:48 Jacob, I really never posted or pictured a how to. I just warned (cautioned) about the 2 little bitty screws that are very tight. Some say you can use a little HF impact driver, but I just used brute force pressure on the driver,....don't let it slip ! Other than that, can I remember ?? You take the tank off (or twist the carb) and take out the 3....or is it 4 screws that hold the cover on top of the slide that contains the needle/white spacer. Then comes those 2 little bitty screws. If you not scared of carbs, not a problem. If any of this is not correct,...help !! :o |
|
Title: Re: Louder exhaust sound Post by justin_o_guy2 on 05/02/12 at 08:05:31 HF impact comes with a skinny little long phillips. Its worth the few bucks to know, going in, that youll get those out & not screw it up. |

Title: Re: Louder exhaust sound Post by Dave Sisk on 05/02/12 at 15:19:21 Hi folks! I'm a new owner of a 2005 Suzuki Boulevard S40. I've been lurking for a couple days now, and glad I found you folks. So, stock exhaust on my bike, and I agree it's too quiet...I like the idea of drilling 8 - 5/16" holes in the existing muffler. How deep do I need to drill these holes? Cheers, Dave |
|
Title: Re: Louder exhaust sound Post by Jacob on 05/02/12 at 15:23:18 Just drill them right through that rear baffle plate and you'll be happy. I am! Just do it same as Routy in this post. It's only like 1/8" think plate, if that. You'll know when your through. Good luck and hope you like it! |
|
Title: Re: Louder exhaust sound Post by Dave Sisk on 05/03/12 at 06:56:21 Cool deal. 8-) Since adding holes reduces back-pressure, will I need to make any carb adjustments after doing this, or no? Cheers, Dave |

Title: Re: Louder exhaust sound Post by Dave Sisk on 05/03/12 at 11:24:36 Yup, I did...so much info that I'm trying to get it all straight. ;) The re-jetting sounds simple enough that I could do it with breaking anything (I'm pretty handy, but haven't worked much with engines). I'm trying to figure where removing the plug in the carb fits into the picture though, and if re-jetting is still necessary after removing the plug. Regardless, not planning to do any carb stuff anytime soon unless drilling the exhaust kinda requires it to keep the same torque/HP. I'd rather get some seat time first and get accustomed to the bike and riding. I'm a new rider, and learning a lot of stuff at the moment. :P Cheers, Dave |

Title: Re: Louder exhaust sound Post by Routy on 05/03/12 at 15:19:08 If it runs good, ride it. If its a bit lean, you're not going to hurt it, unless you are really horseing it hard,......like WOT on a hot day. Do a S plug read after a good run, if it not white like hot, don't fix it, ride it ! The idle mix screw is just that,....it controls idle to fast idle speeds. It does nothing for running rich/lean at speed. |

Title: Re: Louder exhaust sound Post by martinfilms34 on 05/03/12 at 16:11:46 I just did the little drill mod, and i gotta say i like it alot better. Other than the louder and a bit deeper sound it gets heads turning. And I mean that in a way that people, and cars notice you more, making it justa bit safer . Which to me is the main advantage of the louder pipes. |

Cool. Yeah, I agree...if it's loud enough that people *hear* you, that sure seems like a good thing to me. But hey, any excuse will work to justify making it a little louder, right? 8-) My lady friend and I are both learning...and I am just loving this bike. I first picked up a cheap used Chinese 250cc cruiser about a month ago, kinda on a whim, and started practicing in my neighborhood. It was OK (got it really cheap and it's in great condition)...but man, it's heavy (as heavy as an S50!) and hard to balance (at least for me as a beginner). Then ladyfriend wanted a bike...I researched it, and we found her a little GZ-250 (since that's what they use in the safety classes here locally)...perfect for her, but it just felt too pokey for me. Then I stumbled across the S40's, spotted one local, snagged it at a pretty good price, and been loving it since I got it home. Now, of course, she loves the S40 (feels and handles just like her GZ250, except that it's a little heavier and taller, and quite a bit quicker). The Chinese 250cc is for sale cheap now. 8-) Not a complaint, it got me started so that I better knew what I liked, so it's all good. I think the S40 is just a fabulous beginner bike...lightweight and forgiving enough that my dumb-ass can handle it ;), but still got enough guts that I probably won't get bored with it any time soon. And, about the same price most of the 250's local in my area. Just itching for the exhaust to be a little louder and more aggressive though...it sounds like I'm riding a sewing machine! ;D Cheers!

Title: Re: Louder exhaust sound Post by Wake51 on 05/04/12 at 01:59:31 Replace with the HD muffler which you can find loads of info on here for. Honestly it may be too loud for some. I enjoy it, and my bike has a unique sound on this 30,000 student university campus. Just set off 2 car alarms today when my roommate came up while I was putting on my helmet and romped the throttle. Whoops!! But seriously... I get complaints from riders in formation behind me. I'm shocked by how loud the Savage is under load with an after market muffler. It doesn't make a scene at idle but under load it competes with my 1200 Harley and I have to say wins... o.0 |
|
Title: Re: Louder exhaust sound Post by Dave Sisk on 05/04/12 at 05:34:57 LOL. Well, I'd like it to be louder, but not so obnoxiously loud that it sets off car alarms and such. I have really good neighbors in my neighborhood (for the most part, there are a couple of PITA's), and I'd like to keep it that way. ;) I'll start with the drill mod, and see if that satisfies my tastes. Cheers, Dave |
|
Title: Re: Louder exhaust sound Post by martinfilms34 on 05/04/12 at 05:55:59 Yeah, try out the drill mod, you don't really have much to lose of you are aiming for a louder and deeper sound. And best of all it's free. I am loving my savage too, it runs great and I got an amazing deal on it for only a grand. Its a bit older at an 87 but has only 6500 miles, and looks like new. I think it's the perfect bike for me, to use to ride to school, friends houses, and around town. And still has enough power for the highway. |

Title: Re: Louder exhaust sound Post by Dave Sisk on 05/04/12 at 07:22:45 So, I just took a look and the brass plug covering the idle mixture adjustment screw has already been removed on my bike. Cool. My bike backfires just a little. I'd assume that when I drill the holes in the stock muffler, that's going to make the mixture a little more lean, which will make it backfire more (and louder since the muffler will be drilled.) So, based on the article you guys pointed me to, I will probably need to set the already exposed idle mixture screw a little richer to minimize the backfiring after drilling the stock muffler. Do I have this right? :o Also, the idle mixture adjustment screw (the one originally under the brass plug) only sets the mixture for idle. Right? (I understand that's also different from the idle speed adjustment screw, which is the long screw with the black plastic knob on it.) So...re-jetting would allow a richer mixture at speed, so that's the reason to possibly consider re-jetting at some point. Do I have these details right, or no? LOL. I'm enjoying learning all this btw...you guys have a lot of info here to sort through and understand when to do it or not. Thx! Dave |
|
Title: Re: Louder exhaust sound Post by Dave Sisk on 05/04/12 at 10:25:08 OK...I just drilled the 4 rivets out and made 4 holes...I enlarged the holes up to 13/32" (the largest bit my cordless drill will hold, can't seem to put my hands on my larger drill at the moment). Very nice...much deeper exhaust note (kinda like tuning the port size on a subwoofer, I guess)...now it sounds more like a souped-up Volkwagon Beetle instead of a sewing machine. LOL. It doesn't seem to backfire any more than it did, but I'll judge that after a good ride or two. I guess that VW Beetle-ish "whistle" is just inherent to a larger single-cylinder air-cooled engine, eh? Doesn't sound as Beetle-ish when revving the throttle though. Did I mention I'm really liking this bike? 8-) Cheers! Dave |

LOL. I've turned the air/fuel mix screw quite a few 1/4 turns counter-clockwise (and riding it hot). It still backfires some, but not much. The screw is still "inside" the threaded section though (meaning you can see some of the threads in the hole still above the screw, it's not flush with the end of the threads yet). How many more quarter turns ya reckon I got before it's too loose and might fall out? Really liking the simple exhaust mod...man, it sounds like a different bike now, especially under throttle and load. 8-) Cheers, Dave |

Title: Re: Louder exhaust sound Post by Dave Sisk on 05/09/12 at 15:24:40 So, I found my larger drill (LOL) and expanded the 4 holes I made to 1/2" each. The exhaust tone got deeper. This is akin to tuning a subwoofer's low frequency response by adjusting the port size, I guess. I've adjusted the fuel/air mix screw a little more, and it's still backfiring occasionally. I did notice that it seemed to backfire more on a hot/humid day than a hot/less humid day...I read in the tech thread that this might actually indicate the mix is too rich. (It may have already been adjusted since the brass plug was already removed when I got the bike.) The revs never changed audibly when I was adjusting the mix screw, so I think I may screw it all the way back in and kinda start over with the carb adjustment part. :P Dave |

I replaced it with a slightly used Jardine from one of our forum members, and I def like the Jardine better...not as deep of a note in the audio frequency spectrum, but it has a quite loud and percussive bark under hard throttle. You might have to adjust the carb fuel/air mix after any exhaust mod. Check the thread on setting this in the tech section (it's a simple screw that's under a brass plug that you might have to remove and throw away if the fuel mixture has never been adjusted before). Check where it's set now and see how far out (richer...counterclockwise turns) you can go before it's too loose to stay put. This will give you an idea of whether you've got enough adjustment available to do some muffler mods without needing to worry about re-jetting or anything. Cheers, Dave |

Here's how I'd compare those three: 1) Stock muffler: Just too quiet IMO...it sounded like I was riding a sewing machine. ;D 2) Stock muffer drilled: A bit louder, deeper tone (in physics terms, it's like tuning a subwoofer!), but still not what I'd call "loud", plus I still heard that VW Beetle-ish "ping" characteristic to it (which I understand comes from the internal baffles in the stock muffler). 3) Jardine: Much louder than even the mod'ed stock muffler (just short of obnoxiously loud), not as deep as the mod'ed stock muffler, but has a mid-rangey, percussive "bark" to it, and is quite echo-ey loud under hard throttle. This is what I have on mine now, and I quite like it. Thanks my opinion. 8-) Dave |

Title: Re: Louder exhaust sound Post by RanDaMan on 06/27/12 at 14:03:09 Yes i was indeed reffering to the stock muffler. This mod seems easy enough and all im looking to do is make it a bit louder so people can hear me coming with out getting into re-jetting (just yet)... It's either that or carry around an airhorn which could have other more entertaining purposes haha ;D The metal shavings wont have any negative effects being inside the muffler? :-/ |
|
Title: Re: Louder exhaust sound Post by Dave Sisk on 06/27/12 at 14:28:12 Yes, drilling the stock muffler is an easy mod. ;) As far as if it makes it loud enough that people hear you coming, I didn't think so myself...but that's me, YMMV! Try it and see, nothing to lose by doing this mod...just check that you have about 3 turns counterclockwise (right guys?) on the fuel mix screw first. (Turn it all the way clockwise and count the turns so you'll know where you originally were, then check you can do 3 counterclockwise turns before it's too loose and might fall out. Then follow the thread in the tech section about adjusting it after you've drilled the exhaust...essentially get it to where you have the highest revs at idle and it should be good, but read that thread so you know all the details. Search for "brass plug" and you'll find it. ) I got most of the metal shavings out with one of those "small magnet on a telescoping rod" thingamabob's, but I don't know of any ill effects if some metal shavings end up left in the muffler. Cheers! Dave |

After listening to most of the sound clips I liked the sound of greg's "Thrush glasspack p/n 24210" the most! I like the depth of the tone rather then higher pitch rev. This muffler would require re-jetting I assume? :-/ |

Title: Re: Louder exhaust sound Post by Greg on 06/28/12 at 05:48:27 Yes. And it is quite loud. I added baffles to it to quiet it down. I never got sound clips though. I ended up removing it and going with a HD muffler with the baffle plug drilled 1/2". Quiet at idle. Not bad leaving my development. Loud when I punch it. I posted the 3/8" clip. I will try to get a recording of it now. It isn't as deep as the Thrush or as loud, but it is what I am going to stick with for now. And if you go with the Thrush, don't wait forever to rejet. I believe running lean generated too much heat and burned out the fiberglass pretty quick. The paint also burned off at the header end. After the 'glass burned out, it was really loud. Still deep, but cop-attracting loud. |

Title: Re: Louder exhaust sound Post by RanDaMan on 06/28/12 at 06:28:13 I think ill try out the drill mod first and see how that goes! I wont mind digging into a re-jet but id rather wait to do somehting like that until I make other changes I have in mind such as putting a K&N air filter on and such. Wouldnt want to re-jet for the new muffler only to then re-jet for the filter change. Ive got BIG plans for the bike over the winter. 8-) |

Title: Re: Louder exhaust sound Post by Dave Sisk on 06/28/12 at 07:42:24 Sounds like a reasonable plan...it costs nothing to drill 4 holes in the existing muffler. ;) Dave |

Title: Re: Louder exhaust sound Post by Greg on 06/28/12 at 13:21:56 Just to let you know, I added the sound clip of the HD muffler with a 1/2" hole in the baffle. http://suzukisavage.com/cgi-bin/YaBB.pl?num=1151331237/3#3 |

Title: Re: Louder exhaust sound Post by RanDaMan on 07/06/12 at 05:32:02 So I drilled out the exhaust over the past weeknd. Def like the sound a lot more :) eventually ill change out mufflers to get a really nice sound! unfortunately I now have a really annoying and attention attracting pop after every shut down. I turned out the brass plug 2-1/4 turns which eliminated ALL riding pops even on hard decel but everytime i shut it off it sounds like i lit an M80! :-[ I dont know how to stop it id rather it pop while im driving then to pop when i pull into someones driveway. ANY IDEAS? :-/ |

Title: Re: Louder exhaust sound Post by rfw2003 on 07/06/12 at 05:46:07 It's normal to have a shutdown poof on these bikes. It's do to the wasted spark ignition system. With proper tuning of your carb it will be more of a poof instead of a bang though. Also note that with a more open exhaust your shutdown poof will be louder then the stock non-modified muffler as there is not as much to absorb the sound of it. The main reason you really didn't hear it before you did the adjustment of the carb and the muffler drilling is because of 2 things, 1 they are set fairly lean from the factory and 2 the stock muffler is very effective at sound reduction to the point that it sounds more like a sewing machine :-? |

Title: Re: Louder exhaust sound Post by RanDaMan on 07/06/12 at 06:11:20 so theres no hope of getting rid of this obnoxious sound? what about with a new muffler? :-/ Id rather a poof then this bang that i have now though. Its like a gun shot. Bike runs great and has zero back fire since i adjusted the mixture screw (it had a few pops on hard decel and shut down) but its like its saving all the back fires during the ride for one loud pop on shut down. More embarrassing then anything i guess. :-[ |

Title: Re: Louder exhaust sound Post by 86-Savage on 07/06/12 at 06:38:16 At first I felt emberassed about the bang during shutdown then I had a bunch of hard core riders tell me that our bikes have a nick name out this way. I thought it was funny and now look forward to the poof. I've noticed that if I don't shut it down right away the poof is very minimal. Oh yeah, they call our bikes " The Little Banger " 8-) |
|
Title: Re: Louder exhaust sound Post by RanDaMan on 07/06/12 at 06:51:46 HAHA "The Little Banger" interesting nick name. :) So if i let it idle for a few before shut down that could help reduce the sound? Its not really a big deal to me but most people would think that sound is due to a bad problem with the bike. I hope the issue is settled when i put a new exhaust and other goodies on over the winter. |

Title: Re: Louder exhaust sound Post by heroicseven on 07/06/12 at 11:58:38 Ran, just let the clutch out a wee bit while the bike is in gear and idling when shutting down, and this alone will reduce your pow 90% of the time. Most of the time I dont really care if she pops but sometimes its just annoying :-[. I.e late at night, in a parking garage, etc. Hope that helps. |

A new muffler won't make the shutdown back-fire go away by itself. It will backfire if it's running too lean or too rich. So, it sounds like yours is about right or maybe a little lean on fuel-mix...so changing the muffler to something more free flow than the drilled stock exhaust will make it backfire more (not less) unless you also change to bigger carb jets. (As I understand it...someone correct me if I'm wrong.) So, I'd wait until you get the muffler you like before you rejet, because you might have to do it again with a different muffler. Check the thread in the tech section on the carb spacer mod...that eliminates the backfiring for most people, although I can't attest to that personally since I haven't done it. Mine backfires occasionally on decel (depending on the weather...backfires more when it's really humid, which suggests mine is running a little rich) and sometimes on shutoff...the backfiring on decel can get a little annoying, but I can live with it...I don't care too much if mine backfires on shutoff. ;D Cheers, Dave |

A couple questions though! (first quote)- So it is possible to completely rid the bike of the shutdown back fire?

(third) - Mine was backfiring on hard decel as well untill i adjusting the fuel mixter screw under the brass plug.(2-1/4 turns out) Now it has zero backfiring on decel or any other operating conditions but NEVER fails to let out a big bang on shut down. >:( |

Title: Re: Louder exhaust sound Post by Dave on 07/09/12 at 10:48:52 (first quote)- So it is possible to completely rid the bike of the shutdown back fire? Maybe. The issue is that when you shut the engine off it stops the spark from occurring in the enigine - but does not stop the flow of fuel or air through the engine. While the engine is slowing down it is pumping air and fuel into the hot exhaust. The hot exhaust system heats the air/fuel mixture in the exhaust......and if the mixture reaches a temperature that will ignite it......POW! An engine that is running lean makes the exhaust pipe much hotter and more prone to igniting the mixture, an idle speed that is high provides more fuel/air in the exhaust during shut down (this is why letting out the clutch may help as it slows the engine down and pumps less fuel/air into the exhaust), and the speed at which you have been riding and the outside are temperature can affect it as well. Getting your bike to run less lean and at a better mixture ratio may change your "POW" to a POOF" like my bike sometimes makes. I am not a fan of getting the mixture too rich and sacrificing mileage to get rid of the "afterfire". If you let the engine idle for 10-15 seconds, let the clutch out to slow the engine down as you shut the ignition off......maybe you can cut down the loudness or frequency of the backfire. I have also found that quicker shifts while riding reduces the backfire during upshifts. |

(second) - I assume youre talking about the "The White Spacer Mod"? and eliminates the shut down backfire or operating backfires? I haven't done those mods myself (I first drilled the stock muffler, then replaced it with an after-market muffler...my bike appears to have already been re-jetted, so I didn't need to re-jet)...but others here have, and I'm sure they'll chime in with the answers. Cheers, Dave |

Title: Re: Louder exhaust sound Post by RanDaMan on 07/09/12 at 11:06:23 oh i had no idea that the back fire was from excess air/fuel igniting in the exhaust! i thought it was from compression left in the chamber and the bang was just the release of the pressure. :-[ looks like ive got more to learn about this ole bike then i thought!! :o |

Title: Re: Louder exhaust sound Post by verslagen1 on 07/09/12 at 11:58:02 To get rid of the shutdown bang, open up the idle mixture screw a little bit more. And check your idle speed, too low of an rpm will cause it too. |
|
Title: Re: Louder exhaust sound Post by RanDaMan on 07/09/12 at 12:13:28 my idle is already at a "higher" speed i can turn it up a good amount more but then it seems way too high for an idle! ill try it out though, anything to get rid of that darn bang or at least soften it up a fair amount! THANK YOU! ill get back to you and let you know if that solves the gunshot! |

Title: Re: Louder exhaust sound Post by RanDaMan on 07/11/12 at 07:58:39 So I opened up the mixture screw a little more (3 turns out total) and it did greatly reduce the bang more of a poof now. but i feel i might be running too rich now? it seems to not have much power when i turn the throttle past 3/4. it climbs in speed but not as fast as when im going from 1/2 to 3/4. and this morning on my way into work the engine cut out twice on decel and it felt alomst as if i was running out of gas. and it woudlnt start back up for a few min unless i pulled the choke out. and I have never had to use the choke before that. :-/ |

Title: Re: Louder exhaust sound Post by verslagen1 on 07/11/12 at 08:32:05 3 turns out, time to go up to the next jet. Idle mixture jet only directly effects up to 1/4 turn range and if you're using choke, it's an lean issue. Which is what you sound to have... maybe a petcock issue. Did you readjust the Idle speed? |

That brass idle mixture screw is a jet? :o I dont see how it could be a lean issue if im 3 turns out? i thought that made it richer? :-? maybe im confusing mixture screws here. :-/ and yes i did readjust the idle speed. i turned the brass screw out in 1/4 turn increments and tested out for decel and power down back fire. after i reached the third full turn out the power down back fire was pretty much gone. the only time ive ever used the choke was this morning and it was only to see if that would help start it after the engine cut off because it wouldnt start up with out it. then i un-choked it right after and rode to work. im getting the raptor petcock sometime this week so hopefully that helps! |

Title: Re: Louder exhaust sound Post by rfw2003 on 07/11/12 at 09:30:33 Yes if your 3 turns or more out, then you need to go up one size on your pilot jet. That mixture screw is what controls the fine tuning of your low speed fuel circuit coming from the pilot jet. With it getting better at 3 turns out that means you have been running lean and you are indeed richening the mixture by turning it out, but since you have reached the 3 turns you need to go up on the pilot jet now.

Title: Re: Louder exhaust sound Post by Wild1OR on 08/22/20 at 23:24:01 I've spent a few hours this evening reading several threads on this forum and on other sites about drilling holes into the rear baffle plate to make the LS650 louder. In some instances, two 1/4" or 1/2" holes were drilled and in others it was even more holes. Almost everyone described the aftereffect as being so loud, that dogs barked and people turned heads. If someone doesn't want it to be that loud, but also doesn't want the stock sewing machine sound, will two 1/8" holes work or would the holes be so small that the difference in loudness would be negligible? |

Title: Re: Louder exhaust sound Post by Fast 650 on 08/23/20 at 00:05:16 The best bang for the buck option is to get a Harley Dyna muffler and rejet the carb to match. The exhaust tone will be much better and it will sound like a motorcycle instead of a Briggs & Stratton. It isn't loud enough to cause problems and the performance increase makes it worth doing anyway. There is a thread here somewhere about which Dyna mufflers are bolt on replacements, as well as how to rejet the carb to work with the Dyna. Also, the last post on this thread was over 8 years ago so some of the information that you have read may be outdated now. |

Title: Re: Louder exhaust sound Post by eau de sauvage on 08/23/20 at 01:03:05 FWIW, we get no shutdown bang or even a muffled poof!, nada. Using a dyna can and a 20 pilot and a 50 main, that's it. Idles at 1200 |

Title: Re: Louder exhaust sound Post by Fast 650 on 08/23/20 at 07:21:59 If just louder is what you are after, drilling the plate will accomplish that. But if you want a deeper sound then a different muffler is the better option. |

Title: Re: Louder exhaust sound Post by DragBikeMike on 08/23/20 at 11:20:00 Wild1, I run a modified stock muffler and it works well. It may not be as pleasing to the eye as a Dyna muffler, but it is not nearly as loud. It doesn't sound all choked off like the completely stock muffler, but its still quiet enough to easily pass our local safety inspection and does not attract undue attention. This old post is extensive. It will show you exactly what's inside the stock muffler, how the exhaust gasses flow through it, how to open it up, and various options for improving the flow through the muffler. I have increased the size of the external transit tube #3 shown in the post. I am currently running a 3/4" external tube and it works excellent. http://suzukisavage.com/cgi-bin/YaBB.pl?num=1526453881 You don't have to do all of the modifications, and the post should give you a good understanding of how the stock muffler works. BTW, nothing will ever make the Savage sound good. It's a thumper. It will never have the deep muscular rumble of a V-Twin. It will always emulate farm equipment. :'( |
