14mm is pretty much industry standard but maybe some else can help back that up.

well i did a compression test after i ran it for 5 min then sat for 15. I got 80 psi in 10 kicks with the throttle fully open. Not so good. The bike isnt very hard to kick so makes sense. Time for a topend now...even though i though it was runnin fairly good.
