I am having problems with my crf cutting out. It was suckin the air filter shut so I made a cage for inside of it. I just put a hrc head pipe on it instead of a stock 450r head pipe. It has a stage 2 hot cam and a mikd port and polish also. I am running a 182 main jet, not sure where the needle clip is set. I haven't played with the jetting yet the guy I bought the motor from ran a mega bomb header and a fmf can. It runs great till about half throttle then falls flat on its face. If I up shift it will start pulling again. I think my intake duct is to restrictive. Does anybody have any idea's if I am right or not.
