There are 2 different bearings for the clutch case lever. 2 different Honda part #'s for the 2 different bearings and yeah one of the bearings is no longer avalible from Honda.
Top needle bearing, Honda pt # (discontinued) 91002-HA2-003 (Koyo) or 91002-HA2-008 (Toyo)
Bottom needle bearing, Honda pt # (available) 91021-148-004 (Toyo)
I think Big Dog has the top needle bearing, at least I think I read that.
