Last weekend was the first time I had the bike out this year (lohg story) and the starter was making nasty nioses like metal on metal. I took the starter out yesterday and I can see some wear on the armature shaft where it rides on the rear bushing (commutator end). I have checked the manual and it does not give any information on replacing the bushing or lubrication so it looks like I will be buying a new starter. I would like to rebuild this starter if possible for a spare. Anyone have any ideas? The bike has all the 04 starter upgrades.
