2004 gsxr 1000 makes slapping noise at high rpm
the motor has about 8000 miles on it it set for a year in my garage once i got it on i made 4 passes on it at the drag strip i noticed the noise coming down the return road 1/8 a mile it ran 618 117mph on stock wheel base. it sounds like its coming from the top. i had one guy tell me it could me my clutch basket. i guess the only way to rreally check it would b to pull th basket out. i have a full tifourc exhaust on this bike lowered with tie downs on the front 15th sprocket on the front power commander and fuel injection mods.
