I wanted to do some jet work. My 250x is mostly set up for high end power and i was just wondering if i only needed to do that one jet or if i have to do them all. Also was wondering what jetting kit to get.
I was told i have a cam from the guy i bought it from. I put a DG RCM complete exhaust system in as well. I have noticed a huge jump in High end power, so me and my dad are guessing the cam was just never really noticable until the pipe was put on.
Agree^^^^^^ Im running a 12:1 high compression piston and a stage 1 WebCam I'm jetted at 134 main and 42 slow jet. so with a cam and pipe I would try Billy's recommendation. make sure you back the pilot screw out about 1/2 turn and reset the idle.
