    310X -14 boost and RPM drop

    Hi guys!
    I have a 2014 310X, and when i hold full throttle it accelerates as it should up to about 95 km/h. then it drops RPM down to about 7000 and boost to 10.

    I have changed,
    sparkplugs
    ignition coils
    supercharger belt
    cleaned the intercooler
    the supercharger seems fine
    I have tried with a different ECU
    etc etc,

    Im out of ideas!
    what bugs me is that it seems fine and then drops the RPM and boost when its starting to come up in speed, any tips is higly appreciated!

    Get your ECU reflashed and forget your problems.

    Region8Ultra250X, it's an automatic tensioner, and it feels like its working fine, the belt feels good.
    Hurricane1000, I have tried with a different ECU that i know works, still the same problem...

    Would your post not get more attention in the Kawasaki section? You're in the Polaris section. You've really wandered out into the deep forest.

    90% chance its going to be either the TYPICAL frozen tensioner .............You might think its good , but unless its been pulled apart this season and greased up , chance are its NOT !!!!!!!!!!!

    or the fuel filter is blocked , due to people storing the ski with less than 90% fuel level.

    start there and report back

    I could be wrong because I had quite a few beers tonight, but I believe this IS the Kawasaki section...

    Have a few more and it might become the Tigershark section lol.
    Check that tensioner and let us know what you find.
    By the way - how do you know ecu is a good one?
