Hi all knowing ones.
My 500cc bike is turning over sluggish and drawing too much power when firing the bike up.
It still works, but not spinning the engine over as well as it should. So need to get the starter off, strip it down and give it a good clean and check over.
I've removed the plastic cover, disconnected the lead and removed the sprocket cover, there are two Allen bolts visible, one is fitted from the sprocket cover side with a bolt on the starter motor side of the crankcase, the other from the starter motor side into the crankcase.
What I don't know, is whether the Allen bolt enters the crankcase from the starter side, is screwed into a nut or threaded into the crankcase, the workshop manual does not say that I need the remove the right side starter clutch cover to remove the starter, I can't remember if there is oil inside that cover, and would rather not find out unless it's totally necessary.
Any one done this recently1731863645331721787062.jpg

When I was racing a 500 I took the starter motor off almost on the daily basis. I was forever dropping nuts, washers and bolts under it. Just undo the two Allen headed bolts, one from inside, one from outside. You can see both in your first picture. No oil will come out. No need to remove the starter clutch cover.

Are you racing? I still have a blanking plate to cover the hole removal of the starter reveals. Also I have a replacement R/H Side cover machined from billet which covers the end of the crank when you remove the alternator for racing.IMG_2130.jpeg
 
Hi Robin,
Thanks for that, I had a tentative go at undoing the Allen bolt on the starter motor side of the crankcase, it didn't turn, so decided before I gave it some real welly to find What it screwed into first.
I don't race it, but thanks for the information about your un-used parts, I'm sure there is someone here that could use them.
I had your extra JE piston, If you recall.
