    90hp Yamaha engine rebuild questions

    Rebuilding an early 2000's 90hp Yamaha right now but having some trouble finding the specs for piston to cylinder clearance and ring end gap as well. All 3 cylinders are punched out to .030" oversize and I am using WSM pistons.

    Would anyone happen to have a service manual be willing to share a few specs?
