So these aren't a single carby? Nasty... How much would they be looking at to get it fixed? Well i'm gunna tear the thing apart this weekend hopefully if the missus gives me some time off, so i'll see what happens then.

 

Did a quick search & found this, but never been there before so can't vouch for the site, good luck, let us know how it goes with the bike
