Fuel Filters - Got The Blighters

I'm hoping someone out there in interweb world can help me.

I need to get a hold of some replacement filters for the Mikuni Carbs on my 1996 Sprint 900. I say replacement but I should say missing.

These are the really small ones that fit into the fuel feed pipes at the carb end.

I've been all over the web like a fat lad in Greggs (wow just described myself to a tee there) but can't find a supplier anywhere.

Thanks in advance.

Graham

Got them from the Main Dealer
