accually i have a question of my own, i have my quad in my shop right now and i was wondering what my new jet sizes should be? i have a 11:1 comp 426cc wiseco piston, the stage 2 hotcam cam shaft, head had been polished, full HMF sport racing exhaust and i should be getting the 450r carb soon, but right now i was wondering what the jetting should be for the stock carb
