    Hello!

    Can someone give me some baseline jetting for 28mm pwk carb. I think that 100 main and 38 pilot would be good, what do you guys think?

    I have 160cc yx with tb v2 head.

    Is it a genuine Oko?
    If so, then yeah i'd go with a 38 pilot jet and 102 main jet.
    tune it and try it out, then you may possibly need a bigger jet in the main

    Is your exhaust completely open? No baffles? I believe my exhaust is almost 40mm
