mikuni carbs

I don't know a huge amount about carbs, but even I might be able to help with a bit more information. Have you got a pic of what's broken?

 

yea pic or diagram circled with the broken area would be helpful.

 

Superglue? Lol nah I joke. If you don't mind too much, just take it to your local fixer, shouldn't cost you more than $25 and it'll save you the hassle of doing it yourself.
