Rattling sound near clutch cover
I am a bit stuck with this one.
Recently I replaced the starter motor along with several other repairs (new igniter, solenoid, headlight). When I started the bike there was a knocking rattling noise that hadn't been there before. I have tracked it down to the vicinity of the clutch cover. After reading about the loose alternator through bolt issue I removed the alternator but that isn't the problem. I took the new starter motor out as well. Then I found what seems to be a lot of end play on the sprag clutch gear that the stater motor drive engages. It knocks against something when I push it forward (away from the starter motor side). I am thinking it might be the problem.
Has anyone had issue with this or is that amount of end play acceptable? If this is the fault, I am at a loss to understand why it would only be doing this after I replaced the starter motor.
Next question is how do I access the sprag clutch? I scanned the Haynes manual but I couldn't find anything about it.
Any help with this would be greatly appreciated.
