750 Starter Idler Gear Shim
« on: February 07, 2022, 06:18:53 PM »
Just getting round to converting the CR750 back to starter motor and I'm short of the shim that goes between the starter idler gear and the crankcase (part number 28109300000 but not available new as far as I am aware).
Has anybody got a spare to sell me?
Or, if anyone has one off the bike, can you measure the external diameter and thickness please? (I can then try to buy some shimming). It will save me stripping my standard K2 down just to measure it!
I am sure I have asked this before (before I decided to fit the race alternator or when I built the K6 I done up and sold on) - but I've searched for the post but can't find it!
Thanks in advance
Phil

I might have one in my box of CB750 parts. I'll have a look & see if I can find it.

The shim, part 6 on the fiche, is 45mm o/d, 18.3mm i/d & 1mm thick, with a slight step halfway across the width.

If this sounds correct, ping me your address & i'll pop it in the post.
