23 tooth engine sprocket

Post by Columbo John »

Does anyone know where I may be able to source a 23 tooth engine sprocket from for my G12 CSR?

Club spares list one but have no stock and AMC Classic spares don't list it as far as I can see. The part number is 02-3374

Thanks, John.

If all else fails, worth looking at the gearbox sprocket maybe?
If you're on a standard 17 (think that' right for the CSR), a 19 will gear you up nicely if that's the direction you're trying to go. My 650 is 21-42-19-and 'whatever the rear wheel is' and is about right for me anyway.

Autojumbles or Ebay are the best bet. You could try Les at Russell Motors too. Try Steve at AMC Classic Spares he may have a used one.

I will give Russell Motors a call when they open on Tuesday :thumbup:

They list one but the list is from 2005, I thought the prices looked too good to be true :headbang:

Update - neither AMC Classic spares nor Russell motors have these in stock.

Looks like I'm off autojumbling 😀
