have a 2005 and it does the same thing have done a bunch of different things to cure it put a screaming eagle jet kit in it, to cycle shack pipes, to K and N air filter, 1200 conversion still does it not as bad but,still does it. have heard it could be a intake gasket leak so i tested that theory and i didn't have a leak so the only thing i did to make it not do it as bad is put a 175 jet in the carb 1 3/4 drag pipes and a K and N filter on it. needless to say have a pretty fast bike but, still does the carb fart as many people say. hope that helps

What Fox said.

You are describing a carb fart, not a pop/backfire out the exhaust.

It is too lean at idle...either an intake leak or adjust your idle mixture...I am sure there must be a thread somewhere on this board explaining the steps on adjusting the idle mixture screw.

Get it fixed though...you don't want to be in a low speed turn and have it fart...good recipe for dropping the bike.

It sounds like you could have an air leak. You need to eliminate any air leaks before you adjust the mixture, change jets, or whatever. You say you changed the 'intake gasket', what do you mean by that? How's the carb seal ring and the intake seals? How about exhaust leaks?

None of the last three options that you have described in your last sentence will do anything to minimize carb farts! A larger main jet would have no influence in the area where he has described the farts occur, a K&N filter would make it leaner than stock and drag pipes with no baffles could only make things worse. If you have done this and nothing else, that's why you own farts haven't been minimized. Following your advice won't help.

Unfortunately, it won't help.

It's not the nature of the beast; it's the nature of a bike that isn't correctly maintained / tuned.

No jets on the Keihin CV carb are adjustable but they are replaceable. Your pilot jet and idle mixture screw have the most influence on carb farts, Leaning it out further with a hi flow air cleaner and unrestricted exhaust can only make it worse until the mixture is corrected. Increasing the size of the main jet won't help at all as the engine isn't running off that carb circuit when carb farting.
