hey whats up guys, quick question.. my cbr f2 runs great but when i am at very high rpms (10k-up) it starts to jerk, kinda like something is cutting out... could it be my carbs? or a vacuum line? any help would be awesome. thanks all

 

Well the fact that it runs good down low..I would suggest you inspect your air cleaner..if it is dirty it could be starving for air at HIGH RPM...or your have loose sparkplug caps??
Without hearing it it is hard to diagnose

 

Check your fuel lines I just had the same problem
My line from the tank to the carbs was pinched
If you just have a rubber hose that is not preformed that could be the problem
the OEM hose is 8$ I put one on and havent had any problems since
