can anyone help me i have an 01 warrior just bought it has a fmf megamax pipe and k&n all else is stock wont rev up very high just pops
went from 145 main to 155 to 167.5 all same took air filter and lid off box now revs not sure whats wrong

 

Parking brake on? Is the rev limiter switch possibly broke?

 

not sure if its broke didnt know it had one it cuts out at about 3500 ish i would have to guess and i have to short shift it where does the
rev limiter kick in?

 

unplug the parking brake switch from the wiring harness and try riding it, unplugging it bypasses the switch.
