What would the CR be using the 9.8:1 Flat top pistons / 84cc combustion chamber and 0.030" head gasket and CR with 0.040" head gasket? I'd like to stay 9.5:1 or less.

Any idea what the cranking compression would be with this cam?

Have you ridden your buddies 98" 26G? How does it feel in comparison to your current set up?

Cheers,

Ben

.030 = 9.7 CR
.040 = 9.5 CR
