AKheathen Posted November 11, 2012 Report Share Posted November 11, 2012 stock stroke 20cc domes, +5.5, and 93-95oct, depending on how i mix. sometimes even on strait 90, if i feel ballsy....... been working on growing out the balls lately. ask your builder. it is more based on dynamic compression and squish characteristics. that judgement almost always comes from experience.

outlander1000 Posted November 12, 2012 Report Share Posted November 12, 2012 I ran 180 psi on 93 mixed with 110. On the jetskiis can get away with 93 at 185 psi. Quote Link to comment Share on other sites More sharing options...
