    2001 XLT 1200 help

    The ski fires right up but as soon as you go it is like you never get up on plain and max rpm is 5500. checked compression in all three cylinders and it is 130,130, 130. Removed exhaust and cat is good (replaced last year) since it is off i am installing d-plate now. Fuel valve is very hard to turn so i have ordered a new one. But i am thinking it has to do with the PV, i did check to see that the hole in the wheel and the hole in the block do line up and they do. How can i check that they are functioning correctly when running? or should i be looking at something else? carbs will be off tonight so i can look at the reeds. thanks

    lash the powervalves in the open position and give it a test run. That'll tell you real quick if it's a pv issue.

    I don't know if it's suggested to open the powervalve covers and lash the valves themselves, but that's what I'd do at first glance.

    My XLT jumps up on plane at 3000 rpm.. are you sure you don't have a cavitation issue?

    i give it full throttle and it will not get past 5500 rpm and just gets up on plane and maxs out at about 35.

    Is there a way to see if the servo motor is working? correctly? or at all?

    You should hear the motor cycling after you bump the starter a couple of times....

    Just manually open them and run it. If it winds up to 7K you know it needs to be replaced. I think Jeffsntx had one of those a while back.

    To test will take you 10 minutes.

    Twice this year I had a problem with a broken reed - The ski would build power to 6500 if I feathered the throttle. While you are testing the PV motor try it.

    Another option for your PV motor is attached - this is from the GPR manual

    I DID have one until about 3 weeks ago. I am on the same bandwagon with everyone else. It sounds like a P/V, or a fuel related issue.

    I would just bypass the fuel selector until you get the new one and see if that does anything. You might also want to change the fuel filter.

    For the record my step father had the same ski brand new and the fuel selector valve was always VERY difficult to turn. Not saying not to check it... just that it's pretty normal for them to be hard to rotate. GPR is a little easier since the selector is larger.

    here is what i found
    1. two reeds had cracks on the corners and one was burnt-replaced all
    2. replaced fuel selector
    3. installed d-plate
    4. installed cat temp sensor
    5. installed block off plate
    6. checked carbs and all ok (only a couple hrs on them from last rebuild)

    Put the ski back together and pulled the covers off the p/v and i hit the start button a few times and nothing happened with the p/v. Does the ski have to be running for them to do anything?
