    01 GPR 800 Questions

    Hi all,

    I have a friend who has an 01 GP800R, his ski seems to do fine until you start getting to WOT. It is only generating about 4800 rpms, so that leads me to believe one of two things. First is tach isn't working correctly, secondly he isn't getting full power out of his motor.

    So what is the correct top end range for RPM's at WOT on the 800? Is there a way to test his tach and see if it is reading correctly? When at WOT it does feel like the ski wants to jump a little more but doesn't, almost like a mild surge.

    We tried finding the HS jet on his carbs but I could only find one which doesn't make sense to me, so I have to also ask what are the stock carbs? Mikuni SBN 44's?

    Don't know if they are or not. He just bought the ski, and it had a relatively new motor in it. I didn't realize the 800 was a PV motor I thought it was only the 1200. I think I saw a thread about how to check the Power Valves, so that will be the next thing to check...

    Thanks for the input...
