    jetting help

    I have a 84 200x, that is getting rebuilt. I have a 12-1 wiseco piston, unifilter and an aftermarket exhaust. Where should i start with jets? I beleive it should be a 110 in it right now.

    For those mods should start with the next jet up or what?

    Start there. Compression changes should not effect jetting.

    go up one size and start there....prolly have to adjust the needle clip too...youll just have to play with it to get it right...every motor runs a little bit different...this place sells cheap jets http://www.jetsrus.com/ good luck
