Tech Notes: *NOTE: To confirm the main bearing fitment clearance you must take the standard bearing measurement and multiply it by 2 then add that answer to the left side sprocket shaft meaurement. For example the standard bearing measures .250 multiplied by 2 equals .500. The left side sprocket shaft measures 1.000 adding them together you get 1.500 which means you're running 1.501 fitment with .001 clearance.
