I agree. My Honda 200x stock was 9.6:1 and was kick start only. When I bumped it up to 10:1 it was a lot harder to kick start and not to mention if you hit it just right you will damn near break the kickers leg.
but man she run like a bat out of hell. Back then we use a high tech 6" wide HF bench mount belt sander to shave it down. lol
