I have just gone through the machine shop exercise (best mate runs an engimineering workshop) and we have fitted a BK1210 closed cup needle roller into a spare bendix cover I bought ages ago.

As they say, a coat of paint hides a multitude of sins and only a purist would pick that it's been modified.

Fitted it and only marginally better. Turns further but not over.

Today I was in the shed and had an idea. I thought 'Clearance Clarence' and just for schitzengiggles backed off the bendix cover screws. Cover didnt look like it moved, but more movement in the starter. It turned over.

I made a new gasket from .75mm paper and fitted it and first punch to warm the battery, second punch, it spins like a top.

And seems repeatable from cold. Last attempt I forgot I still had the plug in the pipe but it still wound over.

Based on previous exuberance, YMMV.
Change the OEM screws of the Bendix cover with allen head screws. On two bikes that had the same problem we solved them by checking how easy the upper gear can be turned while tightening the cover. On both bikes the cover or its screws were the problem.
