    1996 Polaris SLT780 up 1000RPMs after a jump.

    I have a 1996 Polaris SLT780. At high speeds/RPMs almost always after taking a little air the engin RPM jumps up about 1000RPMs for a couple of seconds and the engine shuts of. The engine seems to be flooded at this point. I choke it and it start right up and seems to run fine unitl I take air a close to top speed, and the same thing happens. Does any one have any suggestions.

    Are you dropping of the throttle when you get air?

    just for a quick test open the high speed screws 1/2 turn and see if the extra fuel keeps you running.
    Possible small seizure due to no or little fuel.
    And for gosh sakes, let off the throttle when you're in the air.
    You have no water intake and the engine will get very hot while at high RPM's.

    ph2ocraft,Thanks for the suggestion, I will give it a try this weekend. I am not talking about serious air, inches not feet, just hitting a small wake will cause the problem. It actually tends to happen when it lands.Could the jolt affect the fuel level float sensor? I know the Polaris has that low fuel mode when below 1/4 tank.Thanks,Ktho
