junkyarddog Posted March 19, 2014 Author Report Posted March 19, 2014 188 is what Jim at passion racing said he done the bore job for me theses cylinders came off a flat track quad and had 17cc domes running race fuel if that helps any to get a idel on the porting Quote

junkyarddog Posted March 19, 2014 Author Report Posted March 19, 2014 I got a set of 22's I'm thinking when parts come in ill slap them in and check compression and go from there Quote
junkyarddog Posted March 25, 2014 Author Report Posted March 25, 2014 Need ideals here I put 22cc domes in to test compression to se where I'm at and it made 100psi wtf right so now I'm thinking I need to go buy some 20's maby 19's?? Quote
junkyarddog Posted March 25, 2014 Author Report Posted March 25, 2014 I dident check seeing its all stock stroke and cylinders now if it was a high compression reading I could adjust it to less with base gasket but i dont think there's a way to adjust to make less squish is there Quote
junkyarddog Posted March 25, 2014 Author Report Posted March 25, 2014 I'm going back to get the 22 domes and put back in a check it I had passion bore the cylinders and there good also the ring end gap was spot on at 10thou so now I'm heading to a buddy's house to pick the 22's again and check squish easy pezy Quote
junkyarddog Posted March 25, 2014 Author Report Posted March 25, 2014 The gasket kit was a K&S? Maby there to thick ill know as soon as I get the squish check Quote
junkyarddog Posted March 25, 2014 Author Report Posted March 25, 2014 I'm thinking it might be thicker but don't know Well I checked squish with a pice of sod I have here that's .062 and piston don't even hit it so now I'm going to the auto parts house and gona get a little thicker sod so I guess I might be looking at new base gaskets after I measure what I got now?

junkyarddog Posted March 25, 2014 Author Report Posted March 25, 2014 Ok average was 58-60 so ? Tear down and check thinness I guess never checked I'm running the kit off eBay that came with hit rod crank and wiseco 65.50mm pistons and gaskets wtf!! Needs to be done by Tommorow Quote
