[tjsdaname]

how far can a stock cylinder be bored out to?? and would you feel a difference in power??

u can go 2 over which is max and ur not really gonna feel that much difference mine is 1 1/2

I herd you can go up to .110 over but i just herd that so dont yell if its wrong

dealership says .090 over

the more you bore it out, the more metal you lose to displace heat. when you get close to the sleeve wall, you can have heat transfer problems. the sleeve is presses in to the jug, so there is an air gap... even though it is nearly microscopic, it matters.

when i bought mine the head was at .100 over i bought a piston .150 i was told that u can go 2 over the guy at the machine shop is doing it now so u must be able to and its a stock sleeve so..unless someone is lieing to me i heard 2 over

.100 over is more than 2 times. Normally .10 at a time, But it could have blown up bad lol
