    Question Kawasaki f15 purchase

    hello i am looking to purchase a kawasaki f15 this friday. Wanted to know should i be looking for anything in-particular. it only has 36 hours on it and is a 2006. The machine looks great. Please Help or any suggestions.

    Lastly, I have a compression tester.... but what should the 4 cylinders be at? I understand the 3 cyl. ratio. but now its a 4 stroke... what should the compression tester test at?
    any help would be appriciated.
    Thanks

    Comp should read 220+ psi with less than 5% difference from each jug.

    The plugs are really deep on the 15F. Be careful not to have your compression tester adapter get stuck in the plug hole. Also, it uses a really small adapter, I know my set wouldn't fit. Also, the 15F is a 4 cylinder, not a 3 cylinder.

    Yes i am aware that its not a 3 cyl.... its a 4 cyl... thanks. Stuck in the plug hole?? how deep you pushing that thing in? it just has to seat the rubber around the hole to get a full count.... or at least thats what i did with my 1200xl yami.

    any ideas on what i should look for on this particular machine because i am purchasing it this friday... only has 36 hours... all stock.... looks awsome from the outside... but who knows... help...

    Cylinder Compression
    Usable Range: 1 185 ∼ 1 795 kPa (12.1 ∼ 18.3 kgf/cm²,
    172 ∼ 260 psi) @430 r/min (rpm)

    Thats right out of the 15F Service Manual
    172-260 PSI

    Make sure you test ride it and are able to get it to the peak RPM's at full throttle. The engine could be damaged and still give proper compression readings.

    The plug holes are really deep.

    FYI, these engines are not cheap to rebuild especially if you need a crankshaft and engine cases.

    any ideas if there is ice where i could test the machine... and not possible to ride.... because of the ice.... test though a flush kit? would that be ok to do.... or should i find a way to wait it out till i can take it out into a lake or something.
