Hey everybody, i havent posted for a while. I recently just bought a 2013 TRX250X with maybe 50 hours on it. The guy sold it to get a utility quad. It is completely stock and almost new. I just received my HMF Performance series FULL exhuast, UNI-FILTER, and Dynojet kit in the mail i bought for it that im installing. I plan on keeping the airbox lid on. I live in Alberta (760m Elevation). Just wondering what jet you guys would recommend. The kit came with a needle and what appears to be a tool for the fuel mixture screw.
