    Slow acceleration, or when you squeeze the trottle nothing happens. If you do ride in the ocean there is a good chance the throttle body may have siezed. It can be fixed but one must have good mechanical skills. There is a small needle bearing on the throttle plate shaft and what happens after a while is that the forced air from the supercharger sends moisture with it and dries out the bearing and causes it to seize especially if the craft has been laid up for a couple months. A good prevention that i've noticed is to leave the breather hose that comes from the engine to the filter tube on, this sends a little oil moist air through the intercooler and inside the engine, it also helps with the valve longivity.
    Hope this helps.

    Have seen it throw the idle way off. Start right up and rev out.
