Mikuni dual carb rebuild

[SuperJet-Dave]

I just spent over $80 and 2.5 hours rebuilding my Mikuni dual 38 carbs for one of my SuperJets. I use the original Mikuni build kits (just do not trust the OEM kits). You end up buying 2 full rebuild kits, when you only need 1 full kit and 1 not-full kit. You waste a bunch of parts, diaphragms, etc. Anyone know of a way to just get the Mikuni rebuild parts needed for the SuperJet dual carb setup?

@Rdrttoy sells individual parts

This^^ He sells just the diaphragms and check valves.

So did you clean out the bypass holes and how many were there? I am doing the same rebuild and only see 2 bypass holes (not counting the one on the engine side of the butterfly). I want to know if I am not seeing some bypass holes....seems important

I cleaned and blew out the "holes" where the filter is, the needle valve, low speed adjuster, & high speed adjuster. Did not mess with the jetting, so did not clean out those areas. I am no expert, but I think that gets most of the fuel and air pathways, including bypass holes. Happy to be corrected by someone who knows this better.

As stated above I have the individual genuine Mikuni parts in stock. I can set you up with exactly what you need and I will save you a ton of cash. Shoot me a PM to get setup.

Good to know these parts are available individually! Just rebuilt mine last night and like stated you have to buy 2 full kits and then your stuck with a bunch of left over pieces.

I'm stumped with one part tho. Does this side only need the o ring is does it also need s diaphragm?

The side with the o-ring gets a diaphragm. The other side gets a gasket and a diaphragm (assuming these are 38's. 44's get another gasket).
See diagram in the attached Mikuni sbn Manual.

That side only needs the o ring because that carb setup only uses one pulse fitting.

For future reference it would cost you $36 plus shipping to rebuild those carbs with genuine mikuni parts if purchased from me.

Thanks for clarifying that!

Rdrttoy that is great. Wish I had asked before buying 2 full kits for much more $. Will look you up when I am doing my next rebuild. Have 3 SuperJets. Others, pass the word around.
