My C15 ss has , (I think) 8 1/2: 1 compression ratio.
If I skimmed the barrel by 1 mm, would that raise the C/R to 9:1?
Bore is 67 mm. stroke 70 mm. My maths is no longer good enough.
Would this be a good idea, for more power, but still nice to ride and start?
Would Higher C/R be worth trying? I could always fit thick gasket to take the ratio down again.
