Replacement parts for KZ650 H2-H3 (or Carb from different model)

1) Did anybody look for Carburetor Rebuild Kit for KZ650 H3 or H3? It is impossible to find. I figured out that KZ750 R1 has the same parts like KZ650 H2-H3 (I compared to their parts no.) but unfortunately parts listed below have a diffrient parts no.

- Do you know/think those KZ750 R1 parts will fit carb KZ650 H2-H3?
- Where I can find parts (replacement parts) for this carb?. Z1enterprise.com has only main jet.

(KZ650 H2-H3)
16017-1097 JET-NEEDLE,Y-7
16009-1098 NEEDLE-JET,4D30
16030-1018 VALVE-FLOAT,2.3

(KZ750 R1)
16017-1109 JET-NEEDLE,Y-9
16009-1114 NEEDLE-JET,4BE4
16030-1016 VALVE-FLOAT

2) What exacly I need to replace if my carb leaks? (Gas is spreading out to Air filters)

Thanks for help

I know this is super old but I am in the exact same situation everywhere says it's obsolete is it transferable anybody

KZ650 H1 H2 H3 have Mikuni BS32 carbs.... not a lot of parts available.
You could replace the carb rack with BS34 from a KZ750. You need new intake rubber ducts and carb holders. A little airbox trimming could be neccesary.

undiablo, the 81 CSR has vm24 carburetors. If he has an 82 or 83, then the carb holders & airbox ducts are the same as the 750-4s and all of the 650-CSRs should have the same airbox as the 750E/H.
