    Kawasaki 650 reeds (are these shot)

    So Iím working on a jetmate for a customer who got water in the engineÖ

    Itís been a long road this far:
    starter relay was corroded to the point it was killing spark so I replaced it.

    still not getting the skis to fire other then juice down the throat of the carb and that was very spotty at best. After going thru the carb several times I decided to check out the reeds. This is the first time Iíve had to even consider the reeds might be a firing issue.

    Currently ski has spark in both holes, 145psi in both holes.

    Any tips for you gurus ?
    here is what the Better of the two reeds look like (to me they look like hell but wanted to hear from you guys.

    TIA for your time and information you can share.

    Reeds have a lot of bad fuel goop on them and possible rust issues
    Should be replaced
    Is it sparking now ?
    just get whole reed blocks with reeds on them , good used

    I am sorry, but you're done.... IF your reeds look like that, I promise your crank does as well, and the bearings are shot. Even "IF" you get it running, it will quilt with a bad crank failure in short time.

    Plus one with John. That thing sat with water in it for long enough to rust everything inside. It won't run long 'til it spits a rod out the case.

    Re: Kawasaki 650 reeds (are these shot)

    Spin crank by hand with plugs out , listen and feel bearings growling , rock back and forth
    Jet mates always come in with water in engine , stored outside , no cover , rain fills up the hull , gets in engine , done , when was the jet mate last registered ? That mate was new to your customer , not an old unit that they have had for awhile and this just happened , I’ve got a good complete 650 engine out of a mate if you need it , also have good reed blocks , check that crank , now might be the time to go 750 BP and be done with it , your there to make money and help out a customer / friend with a mistake they did to themselves , we’ve all been there , trust me , and you always loose when you try to SAVE someone $$$ , on something that was their mistake , just fixed two tigersharks that the guy buried himself in , made him a deal , made money , he was happy , do the same with this project or get paid and move on , get your salesman hat on and sell him an engine , in the long run both of you will be better off

    A thorough engine inspection is in order.


    Kawasaki 650's have a common hard starting problems that
    most likely are not going to get better with just a new engine.

    It would have been nice if you also supplied a picture of the
    reeds without all that rust (but I am glad you did). From what
    I can see (in your horrible picture), the reeds look ok.
