*NOTE: Numeral "7" stamped on rear motor mount halves, to denote 74 cubic inch. Builder may stamp these numbers in.
*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.
