jasons Posted January 14, 2012 Report Posted January 14, 2012 I am in progress of building a dune port 4mm and was curious of jetting. my mods are in my sig. the current jetting was for a stock crank, dune port setup with 30mm OKO carbs. now that i have added a 4mm crank how much will that affect my jetting.

Surfrjag Posted January 15, 2012 Report Posted January 15, 2012 (edited) i would maybe go up 1 on the main and go from there.... also with those oko carbs i always check the float height, they seem to be far off from the factory. have the same specs as a pwk28. i think its 19mm Edited January 15, 2012 by Surfrjag Quote
