Posted May 12, 200618 yr I have a FZR400 1WG,which is running fine till I reach top gear, then after a few minites in top gear it starts pulling back as if it is running out of fuel - but it is not. I have put a new rectifier on but sometimes the idling still sticks at 2500 revs and then will slowly reduce back to tick over. I have also replaced the main jet "O" rings - but still have this problem in 6th gear - can any one please help. The bike is on a D plate but the engine is not original - it is newer.
May 13, 200618 yr You need to really thoroughly check the rubber conectors from the carb to the engine, you may have a very faint air leak.
