hey i going through a jetting battle with my xr50 it runs pretty good right now but the problem is the bike is hitting rev limiter but its not making sense? its not reving all the way out and the revs are bouncing due to a jetting issue. Bike set up is as follows 88cc tb kit no cam and with keihin pe 20mm carb,stock pipe but with baffle and spark arestor removed, mild head porting and intake porting and uni air filter oh and high comp piston current jetting is what the keihin comes with stock 100 mj and 58 pj aside from that motor is stock if its any constilation it used to be seemyzwheelie's old 50 just a nh stunter Anyone got any clue what to do to fix this problem as in jetting tips. i know my cdi and stator and electrical is good
