Title: Turning 550 carbs into 500?
Post by: Honda Al on June 28, 2016, 07:34:21 PM

Hi all,

After looking for information on this I just want to clarify - can I turn Keihin carbs 069A (550) into a Keihin carb 627B (500) by just changing the internals? jets, pilots, etc. The bodies, fittings, etc. are the same across the two models?

Thanks, Alan

There's virtually no difference between the sets. The main jet size is the only major difference as far as I'm aware.

Thanks James.

Did you get my message about the exhaust I've imported south for you from Steve?

Hi Al - no, but I'll check my Pm in a moment. Running a little behind on all fronts at the moment...
