Apologies for bumping this.
have pinged an email off to bike bandit - is there anywhere else that you can recommend i might be able to get the float needle seat from? - that's basically the only part i need to restore my original carbs back to life - and hopefully fix my bike for good.

Also, whilst i'm asking, what is the bore on our stock carbs? i've seen some on ebay which i might be able to cannibalise but they're apparently 36mm bore? i thought that was stock but i assume i'm wrong?
