    Issue with acceleration

    My Waverunner 800 XLT has been having issues with acceleration. Beginning at idle, if I pull the throttle to 100% it only accelerates like I'm pulling it at 40%. Then, when it hits 3000rpm, it floors itself all the way to top speed. Trying to maintain a constant speed is difficult, because if it drops below 3000rpm, the gas basically cuts out. I haven't done any modifications to it either. Any ideas?

    I have an 03 xlt 800 and it runs about like yours. Dead spot accelerating then comes on hard. I have changed plugs, I think there're just set rich from the factory.

    I believe I have changed the plugs, but I will look into that. The problem just seemed to come out of nowhere, which is a little unsettling.

    If the carbs and in good shape, check the powervalves-could be one or both stuck open

    I'll look into that, thanks.

    I agree, sounds like a power valve issue.
