i was running a stage three hot cam on a stock motor with a yoshi full system. jetting was like a 180 dyno jet and i just bought a ported head so if i put that on i assume im gunna have to change the jetting. i did some searching but got more confused on where to go with the jetting. i figured i would have to bump up the main. so any help would be great.

I have pretty much the same set up. Stock motor other than a crf cam and ported head. Running a 13:1 190 main n its perfect
