Topic: Switching out carbs on CB650

[cb650guy]

I have been having the hardest trouble getting my 1980 CB650 to run.  I finally took it to a mechanic and he said that the carburetor bodies are so corroded/oxidized that the carburetor needs to be replaced.  I was semi-expecting this because I thought the same thing when I was cleaning them.  There are not many options available for purchasing a set of used carburetors off of ebay for the mechanical slide cb650 carbs.  I have seen several references on this site to members using carburetors from different motorcycles, possibly the 1977/78 CB750.  Can anyone give some insight into this switch?  What would have to be replaced besides the carburetor? 

Thanks,
Adam

Are these the slide carbs, or the CV carbs.

These are the mechanical slide carburetors.

79/80 are mech.    Soos has a thread about the other carbs he got to fit.
