Well I owe Islander an apology, as it was obviously the slider he was alluding to. I read it as meaning the old fashioned internal choke slide.
If the slider is crippling in it's track, then replacement is probably going to be the only cure.
Moto Rapido would be my first call. 01962 877998 then 1 for parts. You will speak to the extremely helpful and knowledgeable Craig or Luke, and also qualify for a discount as a UKMOC member.
Failing that you could speak to the very helpful Paddy at Ducatipaddy
