Includes a dome locking system that prevents it from spinning when servicing spark plugs.
Not all cylinders are the same and compression may vary.
85 mm domes (760) are intended for use with 84.00 mm to 85.50 mm piston size.
760cc COMPRESSION CHART:
85mm Chamber 760 No Porting @ Sea Level (NOTE: Stock 760 Cylinder is 84.00 mm)
32cc = 225psi*
34cc = 215psi*
36cc = 195psi*
38cc = 185psi*
40cc = 170psi
(* = must use 100+ octane fuel)
NOTE: These are estimations only. Many factors could change actual compression (port timing, squish, deck height and piston selection).
