    951 engine surge @ 6000 rpm

    Looking for experienced, knowledgeable Sea Doo riders/mechanics to shed some light on this occurrence. I have a '02 RXDI that when a constant throttle position is held with RPMs @ around 6000 it has a consistent surge. Seems any Sea Doo I have owned w/the 951 engine (ie '98 GSX Ltd, '00 RX w/carbs, '02 RXDI) did this. The surge does not seem to be a detriment to the engine as I have never had any engine problems w/any of the 951 engines I have owned. So experts why does this consistent surge occur @ around 6000 rpm?

    I'm no expert but I owned a 2000 xp & I know the carbs don't like that 5800-6300 rpm range for too long. Lean spot. I don't know about the DI's though.

    Sorry about this forum members. I do not go to the 2-stroke forum very often so I forgot about 2-strokes having its own forum.
    Thanks fazznick for bringing it to my attention.
