1977-78 carb parts interchangable?

[janderson208]

I have searched the GS resources and I was unable to fine any definate answer. Most websites only list parts for 1978 and up.
Will 1978 jets fit the 77 carbs?
example: Chuck Hahn suggested Z1 enterprises, however they only list parts for 1978 and up. By the way thanks for all the help Chuck.
Is it safe to assume that if it fits a 1978 carb it will fit a 1977?

You are correct

[chuck hahn]

yes..the 77 and 78 VM 26 carbs are the same and everything interchanges..

Does depend on the bike. For the 750s there were some different specs - have a look at the carb sticky it's in there somewhere - depends on numbers not years.

They aren't exactly the same, but I've not found that mixing parts makes a discernible difference. For example, the early model 77s carb needles were not spring loaded, the retainer inside the slide was slightly different, and according to the spec sheet IIRC the needle or the needle jet was different. Also the float levels called for a different measurement. Having said that I've swapped internals between the two and provided they are ALL changed I cannot see not have found a difference in running.
The only major difference was the location and design of the choke lever/knob. The later 8v L's had a pull through stem choke knob whereas I'm pretty sure all the standard models continued using the lever on the side of the carb. But that would be no big deal provided you had the parts to swap
