So i just rebuild the top end on my bike and something is not right. Its like the bike is running really lean. I have the timing right.. I have no vacuum leaks on the intake boots, everything is straight. I checked it over and over. The first problem is that my start/idler knob does not work at all. I use to be able to pull it out to start, and once warmed up i push it in and i could click it clockwise or counterclockwise to make the rpm's go up and down, or richer/ leaner. After I got the bike all back together the knob does not work at all. I also noticed now the header pipe is getting really hot and glowing red. Does anyone know if this is because when I took the flywheel off it resets the efi computer? Do I need to take it to the dealer to have them program it again or what? Other than that the bike starts fine. Its acting like the EFI has lost its touch. Its feeling like a 2 stroke.. if I blip the throttle she sometimes dies, other times its like bbrrrrrrAAAAAAAP.. there is a really bad bog which there never was before. This bike use to be a really crisp throttle response and would breath fire.. now she is weak as hell. Anyone have this problem?
