Is it necessary too lube the starter sprocket when reinstalling? Moly, or bearing, grease?

On a somewhat more sober note, I would strongly advise against the use of ANY moly products in the engine.  If you look in the factory manuals, you'll see that they recommend lubricating with clean engine oil.

The starter sprag relies on friction to engage.  Molybdenum gets in there and is too slippery to let it engage.  I know this because about a half hour after starting up my K100 for the first time after a head job where I used molybdenum assembly paste the starter that never gave me any problems stopped engaging.  Had to do an engine flush with Seafoam to get the molybdenum out and since then the starter works properly again.

Puller my starter motor the other day ... after significant effort. Maybe it had never been out.

Anyway, couldn't do it by hand and made a little tool out of 5mm bar. See pic

The two prongs go into the starter holes and a screw driver levers against the vee and the top of the gearbox. Works a treat.

An impact driver might help to undo the two screws. Inside was plenty of crap. Brushes worn unequally and will replace these in near future. Cleaned armature etc with very fine wet and dry and tested.

Q: do you have to test for continuity all around the armature or just once?

Went back together easily enough and made no difference to the inability of the bike to fire into life but at least it was one less uncertainty out of the way.

Pretty sure my no start was bad connection with relays or fuses
