    Question Unstable rpm between 3000 and 4000rpm

    I have been riding my ultra 250 (2007) for approx 15 hours now. And the last few times I have noticed that the motor is a bit unstable between 3000 and 4000 rpms. Maybe this is normal? Does anyone have input to this?

    I have about 15 hours on my ski as well, I am experiencing the same thing. It kinda surges a couple 100 rpm when going thru no wakezones or coming in to dock. I would like to hear some ideas on what it could be as well.
