looking for a klr 650 in south texas

[Michael Hightower]

Hi everyone, I haven't posted here in a while, mainly out of laziness. But I'm still riding my KLR almost daily here in Chicago. So far, I've not found weather that is "too cold" for riding. Anyhoo, since it's winter I thought a fun project might be to make an additional slip-on muffler to silence the bike at parks, campsites or in places where I just don't want to make a lot of noise. (E.g., while riding through a neighborhood and planning on riding somewhere that I possibly shouldn't, but don't want to find out because someone heard me....) So first, does anyone have any good ideas for this offhand? What I was thinking is a canister a bit larger than the exhaust with a flip-type clamp. Slide it on, then flip the clamp, and hopefully the bike will be quieter. But the big question is what to put in the canister? Should I weld in a series of baffles? It doesn't matter if this produces a decrease in horsepower or torque since it would only be for short-term use. Even niftier would be some contraption permanently mounted to the bike that can quiet the bike with the flip of a lever. Thoughts? - Mike Hightower [Non-text portions of this message have been removed]

Does anybody remember these? http://www.angelfire.com/ut/moab/images/snuff-or-not.jpg Maybe something like this would work for you. Fred www.arrowheadmotorsports.com

They were de rigeur if you had a CL77. I cannot recall ever seeing them on anything else.

I had them on my CB160 with straight pipes. Way cool when you are 14 years old, not so cool now. You'd be surprised what kind of exhaust contraptions you see come through a motorcycle shop.

What do you have for a muffler and has it been modified? Makes a big difference on what we can recommend. If you have a stock muffler why not install a 4 inch long pipe on the back and put a cable operated equivalent of a snuff or not in it. Alan Henderson A13 Iowa If you have a really open pipe the added restriction could help your low end torque. Operate from your handle bars with an old style single lever friction shifter for a bicycle.

Michael, Regarding the slip on muffler, there is just such an item made for ATVs. Since they are designed for larger ATVs (i.e. the Polaris Sportsman series, such as the 500cc I used to have), they should work on the KLR with some modification to the existing muffler. Cabelas sells the following (if the link works): http://www.cabelas.com/cabelas/en/templates/pod/standard-pod.jsp?id=0014420&navCount=2&parentId=cat20161&masterpathid=&navAction=push&cmCat=MainCatcat21412-cat20161_TGP&parentType=index&indexId=cat20161&rid= It is listed as Item: IH-521114 if the above link doesn't work, and is called the "ATV Stealth Exhaust System". It sells for $199.99 at the Cabelas website and in their stores, and I am pretty sure I've seen it online elsewhere. I can't say for sure, but I seem to recall WalMart had it in their ATV section, but that is seasonal, so you will have to wait until next year to see for sure. I heard one once, in person, on a Polaris 500HO Sportsman, and it definitely changed the exhaust note; but I wasn't impressed otherwise as the other normal engine noises were fairly loud (i.e. the normal ticking, etc.). In other words, I am sure that others hearing you ride by would notice quite a difference, but you sitting on top of the ATV would still hear quite a bit of what you hear normally. How it would sound on a KLR I couldn't say. How to mount it I also couldn't say, but then most of us here are are into modifying our bikes, so I can't see that it would be that difficult. Most ATV exhaust that I have seen (particularly the Polaris) have a bit of tailpipe sticking out to attach this to. You may have to do some welding to the KLR exhaust for this....... Now, on to exhaust cutouts. In PA, anyway, an exhaust cutout is not legal, however I assume that ONLY means if it is between the engine and the stock muffler. I think that if one was placed between a stock muffler and a secondary muffler, it would be legal; but then some police don't understand to read the "intent" of the law and only read the "letter" of the law, so YMMV. I'd avoid the cutout anyway, as I think they are a PITA. Moving parts on an exhaust would lead to problems, I think. If you decide to try this project, pictures would be appreciated, as well as information on your results......... Chuck F. NE PA 2007 KLR650 2007 Vstar650 Classic

I meant the stock muffler form factor assuming it had been modified in some way to make it loud. Probably should have specified. Alan Henderson A13 Iowa

Yo, In response to the various thoughts: - What kind of muffler do I have now: It's a stock KLR exhaust that has been modified by the PO to breathe a bit more freely (loudly). It does have a nicer tone than I've heard on stock KLRs, even if it is more lawnmower on steroids. - Remember the Snuff or Not: Nope, but that seems like an idea worth investigating, and seems like a better idea than a canister that I clamp onto the end of the muffler. - ATV exhaust system: Seems like a good idea for permanent installation, but since this just needs to be temporary it'd probably be more hassle than it's worth. Neat product, though. It's looks like it's large enough that it probably has little effect on power output. - Exhaust cutout: I guess this is similar to the Snuff or Not, but installed before the muffler. Seems a basically good idea, but again, might be more effort than it's worth. So it does seem that Fred's and Alan Henderson's idea of manufacturing a Snuff or Not might be the best way to go. Lemme see if I've got the idea straight: Tack on a 4" or so long piece of pipe to the tail of the exhaust, and install a butterfly valve in it. Actuate the butterfly valve via a cable (perhaps an automobile Choke cable?). I might have enough scrap here to test the idea. - Mike [Non-text portions of this message have been removed]

Try adapting a pipe-thread lawnmower muffler to the outlet of the KLR muffler (or maybe an array of them painted different colors would look really cool). Fwed
