    carb rebuilding

    Quick question. How far do you go with taking the carbs apart to clean, inspect and replace needles and seats and gaskets and stuff? If you look at the schematic, looks like you have like 500 parts in them!.
    Do most just change the seats and needles and paper and rubber, internal screens and diaphrams? Never done this before. Although I have rebuilt holley carbs and quad-dra-pukes on chevys.

    speaking only for the 650 carbs, they were amazingly simple to rebuild. I think it took 45 minutes per carb to do it. I assume the 750 carbs would be the same.

    I too thought it was going to be this major undertaking after looking at the parts blowout sheet, but in reality it's like 6 pieces or so that you are replacing.

    I drove 2 hours to have Keddano help me (seems like a long time ago but it was July lol) and I was almost embarrassed when I saw how simple it was.

    I actually got the rebuild kits at a local-ish watercraft dealer for $26 each. the diaphargms came in the kit and yes I replaced them.

    I bought the triple fuel pump from the same place for $30 I think.

    seems like ages ago since I have learned so much since then.

    Blegan, you really should use genuine Mikuni rebuild kits.

    I'm sure they aren't OEM at $26 a kit.

    they were in fact Mikuni kits, and I was off a bit on prices sorry...here is a copy/paste from when I got the info:

    "JS Powersports,Cedar Rapids
    call chris @ 319-364-1120
    you need the triple outlet Mukuni fuel pump(28.00),and 3 carb kits (30.00 each)for the SBN 38's Mukuni carbs."

    Wow, that's a great price for OEM.

    I stand corrected....
