    98 gp800 problems!

    Hey guys! I have a 98 gp800. I took it out yesterday and hit full throttle. Then I noticed that I was doing 55 at 6500rpms. Then suddenly I got a burst of speed bring me up to 58 -60 at 7000rpms for abot 3-5 sec. Then back off again and keep doing. Last summer I hit 63 -65 on it and it wasn't doing that. Any suggestions??

    ride w/o the seat and keep and eye on the rotation . here is what I do .I make one line on the wheel and one on the motor housing , then rotate the wheel until stop it should be in the opening position , and mark the housing using the same line you already have on the wheel.
    at that point you will be able to see the wheel move form one line to the other.

    forgot, you will need to pull the rubber bot back at the motor to uncover the wheel. also you may need to unplugged from the hardness to manually rotate the wheel .
    use a yellow permanent marker , something bright.
