i have a uni filter and a fmf megamax pipe how should i jet my carb

 

not the best question but dynojet is pretty good

 

on my 400ex i have a whitebros and K&N so i would bet we wre pretty close to power ratios and what i did to mine is put a 155 main in it and dropped the needle one clip, alot of people didnt't think the needle drop would do anything but i seem to think it helped enough to where i didnt want to change it back.

dyno jets are not bolt in jets and the numbers on dyno jets are different. dyno jets use adapters for these I think its a band aid. If you want nice jets try Jets R Us. They have pretty nice people at www.jetsrus.com and they ship fast. Just my opinion.
