Knucklehead Engine Case Set
Before you order — V-Twin tech note
- *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.
