Then you missed on the compression ratio. You have to make compromises somewhere.

I‘s work on getting the compression down to 11:1 if you want to run that gearing.

What does a 4.10 gear look like for cruise RPM?

There is no option to run 4.10 in this, it’s already crazy over invested project ;-)
I’ll work on the chambers and cc them to see where it takes me I guess.
I should have one chamber ready tomorrow.
Fact is that I need 70cc chamber to be at 11:1 which is unrealistic I guess.
