Title: 15-1525 exhaust valve collets
Post by: Janacek on 07 Nov, 2025, 16:42
Need new exhaust valve collets for my B31 as they all look as though the mice have been at them.
Found a supplier for the inlet collets,but an internet search found no one had any exhaust ones in stock.Dragan Motorcycles said they MAY have some in about six weeks.
Anyone know where I can get a pair of B31 exhaust valve collets?
Thanks.

If you know the exact dimensions you need, there are several sellers on eBay.  E.g. https://www.ebay.co.uk/itm/297197477010

You might get lucky?

Where are you? If you are near an old fashioned car breakers its worth looking at the older engines.  Often valves and collets were standard dimensions so parts from one engine would fit another.

Have you tried Russel motors in London.
