can anyone tell me what's going on with my bike. when i try to give it full throttle it slows down, and i have to let up on it a little bit for it to pick up speed. I'm thinking it might need new sparkplugs. can anyone give me a clue.
it's a '02 600 gixxer

Fouled plugs... crap in your gas tank... FI not working properly... etc. etc. etc.

Sounds to me like a "Secondary Throttle Valve Actuator" problem.

Does your "FI" light come on when this happens?

Could be the "STVA" itself or the "ECM"

one is expensive,.......... the other is very expensive
