I just bought the bike used in January and noticed the backfire about three weeks ago (could have been there all along but as I get to know the bike I notice more and more). Haven't changed anything on the bike with the exception of replacing missing bolts and fiddling with the idle speed screw. No power shortage, mileage per tank is right around 300, sometimes a tiny bit of really faint white smoke during warm up. Could it be something as simple as a bad spark plug? It's a '96 and I doubt if anything has been changed since new (looked like it had been garaged for a while when I bought it). dat brooklyn bum _______________________________________________________ Get 100% FREE Internet Access powered by Excite Visit http://freelane.excite.com/freeisp> > You said that your airbox, engine & exhaust are stock, and that > the 'backfire' existed before you swiss-cheezed the muffler. > Several questions: > Is your bike running well. except for the backfire? > How's the power?
