eh...i rebuilt the carbs on my old cbr (F3) and it wasn't bad...they were kinda testy to sync without the right tools, but it came out ok, if i had some time i'd help you out, but i'm so damn busy. I'm sure there's a write-up online about rebuilding bike carbs...or just regular car carbs...same basic premise. Get the sync tool though...helps a lot! Called a Uni-syn. why not just take it to a little bike shop...they can do it for pretty cheap.
