this is my third 400, so ive been through the jetting process before but im just wondering what would be the best for a perfectly running engine. ill have a sparks key, LRD slip-on, uni filter with no air box lid, and i will get a cam in the future(dont know if that requires rejetting or not) and i might get a rev box but iono about that.
i was thinking, a 160 main, clip dropped one notch on the needle, but how far do you think the air/fuel mixture should be? and do you think putting a 42 pilot in would be the worth the trouble?
