    Re: Latest on 750 crank seals?

    Thanks!!

    I really thought people that were rebuilding their engine had
    only poor choices for main seals.

    John, is this the brand you sell?

    I have used WSM teflon seals, and I think they are good. The ones I stock are sourced, and branded as our own, and are Japanese.

    Re: Latest on 750 crank seals?

    There are many good options (If OE is not available) Pro-x is another good seal.

    I strongly suggest staying away from ethanol fuel at ALL costs.... Our fuel systems are just not designed for it, carb parts, crank seals, fuel selects, fuel tanks etc will all pose a problem with ethanol fuel (Trust me we see it here all the time.) Not to mention ethanol is hydroscopic, and we are running a craft that is surrounded by water, and moisture....

    Re: Latest on 750 crank seals?

    In California, we have been using pump gas with ethanol for decades.

    IMO it is more important that watercraft enthusiasts have sources for
    high quality replacement parts so they do not need to worry about the
    pump gas they use.

    People should be aware that purchasing cheap Chinese parts may have
    unwanted consequences because of the use of ethanol in our gasoline.

    There is a value to products that continue to perform well over long
    periods.

    You still sell Keihin carb kits from Japan? IMO you are a better source
    than Sudco for the average person.

    Re: Latest on 750 crank seals?

    Yes, We stock Genuine Keihin CDK-2 carb, and fuel pump kits. I have 650sx fuel pump kits, but for now the 28mm carb kits have been discontinued. We are trying to get them to bring them back, but for now those are a no-go.

    Even though we have an on line store, my main business here is building / servicing skis. I have been this for over 35 years. I will NOT sell anything on my site that we won't use on customers machines / builds. I will NOT sacrifice quality for availability. I turn away a ton of work as we cannot get quality parts for many older machines.

    We find even with OE, Genuine Keihin, and Mikuni parts that ethanol fuel still makes the diaphragms, gaskets, check valves etc all extra crispy. It literally melts them. I have personally seen fuel tanks dry out, and crack. We find carbs all corroded inside, fuel tanks full of the slury mix of water/crap, and so on. I stand by my statement, to do what ever it takes, at ALL costs to NOT run ethanol fuel..... There are ways you can actually remove the ethanol from the fuel if need be.

    I have to agree with you on this John. I preach this to my customers and show them what happens. I rebuilt a 700 Waveventure over this winter for a customer that JUST quit in July. I siphoned over a gallon of ethanol from the bottom of the tank......it had COMPLETELY seperated.

    While I'm reading this stuff, John, do you have parts for the CDCV carbs? The last set I worrked on had 2 bad needles and needed diaphragms. The aftermarket diaphragms have the needle arm button too thick and you can't adjust it properly without grinding it down by 1/2!

    Re: Latest on 750 crank seals?

    I agree with nearly everything you have said. It agrees with what
    Polaris told us ~30yrs ago, and with what I have seen.

    Despite your sincere warning people are going to purchase fuel
    from their local gas station or marina anyway, and it may or may
    not have ethanol.

    When these people rebuild their engines, it is important to have
    trusted sources that sell the best product available for their watercraft
    with near oem quality when possible.

    Myself - Sorry, I do NOT have new any CD-CV parts available. We have stopped servicing these skis for this reason.

    I may have a used set of carbs.
