my buddies bike runs great in first second and third gear up to redline but when it gets in 4th gear it stops pulling at 9k.it like some one threw on the brakes and the engine dies and the tach goes to near zero.it does not break up at all just dies off.he said it does this in 5th gear also same rpm.just not the lower gears.it has slip on only no pc or tre.they had the tank up to add some chrome covers over frame but it was just up no wires were mess with.they also changed stock gas cap to votex.any one else had this problem.I tried post at gsxr.com no responses so trying here thanks.
