Again as I just stated I tried new plus already , I got 10 packs of plugs so yea obviously I did. I think it's the threads in my domes that are messed up .
They looked fine , but I'm thinking it might be the domes messed up but not to sure, I tightened them what looks like as far as it'll go before breaking an it still leaks so either the Teflon tape works or might have to get new domes cut but thanks
Athena cylinders are race ready out the box for stock stroke. You want power that athena won't give you. Go buy a 10 mil crank an cheetah cylinders. That will blow past the competetion !
