Damnit Bob Posted March 24, 2010 Report Posted March 24, 2010 I am finishing up my motor build and I was hoping to get some input as to where to start my jetting. I am running: 4mm crank, 21cc domes, 35mm PWK's, and shearer inframes at about 1000ft (+/-200ft). What sizes should i start with to get me close?? Quote
