dajogejr Posted June 9, 2006 Report Share Posted June 9, 2006 Jetting shouldn't change...maybe a main size at most. You may, however, need to run either a mixture of pump/race gas or straight race gas. You'll need to get a compression reading to tell if you do or not. Normally...145 or more, a slight mixture of race/pump is a good idea... Generally, over 165PSI and you need race gas.... Quote Link to comment Share on other sites More sharing options...

racer Posted June 10, 2006 Report Share Posted June 10, 2006 jetting shouldnt change with a two stroke head. if it does youve got some funky shit going on. think about it. youre not flowing any more air, just compressing what you had already.
