    External Fuel Pump?

    Hey guys,

    My Jetski Mechanic mentioned he couldn't do something with the carbs and has to put in external fuel pumps, what does this mean?

    Sounds like he can not find the parts for the " Bing" carbs,does he do alot of other PWC work ?
    I'm wondering if Keihin carb parts work on the "bing " carbs.

    My honest opinion -don't waste any money getting those carbs to work,get some used 40mm Keihin carbs.

    Some times you can find them for $100usd or less. But $150 for good carbs is good.

    The X45 was the ONLY model that used the "bing" carbs. So any 98 and newer 3 cyl domestic carb set should work with the correct jet adjustment ,32h2o has done done it,wait for a reply for exact specs,.

    It's an easy change out from the Bings to the Keihins that anybody can do. Just simply unbolt the Bings, remove and replace with Keihin 40's. On the Keihins, just use the 1200 engine jetting specs as used on the 2000 SLX...look in the tech section, I think the manual is there with the information.

    jetting

    i believe the 2000 genesis used 40mm keihins and the log manifold like the x-45,i'd use those specs for the 2000 genesis.

    Depends on what the venturi size is on the carbs he buys.

    40mm Keihins with 31mm venturi:
    Main Jets 135mag, 140cen, 145pto
    Mid Jets 42
    Pilot Jets 68

    40mm Keihins with 35mm venturi:
    Main Jets 140mag, 142cen, 135 pto
    Mid Jets 42
    Pilot Jets 70
