yes i used the same drive on all three starters.i didnt think there was a problem with it.ive been fixing cars 20yrs.the bike thing is new to me.i have had the inner gear of the drive out.it looked ok.i could not remove the sleeve that it sits in because of the flywheel,can i just replace the gear it self,should i also replaced the small shaft that slips on the end of the starter too
