4-5 degree squish angle. .039 squish
170 psi static , but I'm thinking you want corrected? Which I havent figured. Port heights are stock, just cleaned up. Thanks for the response, I just dont want to detonate the guts out of the thing.

I ment 4t ratio.. When all of us around here state our comp numbers it's uncorrected. So we can have a base comparison...
Only one squish cut? Most run 4deg. Into 15deg
Motorrad:

easy to swap back and forth between metric and standard... stupid metric system

90mm bore, 47cc, at stock port heights will be about 7.4 to 1 corrected. 12.6 to 1 uncorrected. That's fine for 93-100 octane.
