    2012 15f jerking

    2012 stx15f

    New pump bearing and brand new engine installed by Kawi dealer.

    Canít go over 4K. Soon as you hit 4.1k rpm it starts jerking back and forth. Any ideas? I just changed plugs too.

    yeah, the installing dealer should be dealing with this, as I'm sure that engince cost you about 5k, if it was indeed a new kawasaki engine

    I'd be checking the fuel pressure out of the gate, fuel pump may need replacing

    Canít upload video on mobile. But compared to my 12f this engine is knocking bad. Not even an hour on brand new
    Motor! Back to dealer it goes.
