some jetting questions¿

[UglyMotha™]

within the next couple weeks i will be starting my quad up for the first time and was wondering what size jet should i start off with right now i have the dynojet kit in it with the dj170 but that was with no motor work so know i need to go larger but to what size i really don't have a clue then i'll do my jetting from there also should i keep the dyno jet kit or should i just ditch it and use the stock needle and regular khein jets and if that's the case what size khein jet should i start out with, it's a 416 with stageII cam ported head stock carb bored to 38mm open air box:confused:

I dont know much about dynojets, but for the kehein i would try a 155 or 158, move the needle to the 4th clip down and bring the air/fuel screw out to about 3 turns. Keep the 42 pilot. This setup should get you close to what it should be, you may need to fiddle with the jet size a little and the air/fuel screw, but this should be pretty close.

Good luck!
