My '00 CBR 600 F4 all of a sudden will not go faster than 90 mph...I am full throttle and it will not go any faster. It starts studdering at 90. WTF???!!! Can someone help me figure out why this is happening? Roar to the Shore in Wildwood is in 13 days and I need to get this problem fixed fast!

HELP!!!!!!!

 

sounds like an air or fuel delivery problem, maybe even a spark problem

 

Yeah, I'm gonna say fuel delivery problem. How long has it been since your fuel filter was changed? It may be flowing enough fuel for around town, but once you go WOT it can't get enough gas through it. That would be the first thing I'd check.
