2004 Busa, 12,000 miles, had it since new. Only mods are punching some holes in stock exhaust baffles and a larger rear sprocket. For the last year when slowing down for a stop, I occasionally get a very loud exhaust backfire. Once in a while the bike stalls. I'm wondering what could cause this. Leaking injector?
I have a number of other bikes but the Busa always seems to be the PITA. I have had starting problems with the bike since new. In hot weather, if I stop after a ride and then try to start the bike after a short wait the engine "kicks" back and stalls the starter. I've lost track of the number of new batteries I've put in the bike. I always buy a battery with higher CCA than stock. I think when I perforated the exhaust baflles the starting problems got worse. It can now take multiple cranks to get the engine to light off.
