    My ski's speed.

    I went and rode last sunday and with two riders my Ultra would only read 53 on the speedometer.

    I think it should read higher than that. I know they are inaccurate but come one, then I think it's slow.

    When I'm idling, it says I'm going 0. What does it say on yall's?

    my speedo has read 53 before when im really going 63. i would be more concerned with your rpm's right now. what are your max rpms?

    The highest speed I got was 53 and the max recorded RPM while running at that speed was 7710.

    And that was with two riders.

    160 myself, 220 for the other rider.

    i think you will be satisfied when you get your gps . it also makes a huge difference if your tank is low on gas and you shift all your weight to the back of the ski.

    How do you lower the wheel on the back to give out higher readings?

    my reply from the other site


    max boost on the ski is 11.5 PSI so it will never read all the way to 15 at full throttle

    how long was your short speed run? unless you wind it out for a good 1/8th mile you are not going to get a max speed run on the boat especially with two people

    my speedo never reads above 53-54 when i am running wide open but peak speed and rpm are always spot on

    i run around 65-66 wide open on gps with a 1/4 tank of gas and i am around 285

    never tried it.... i would imagine loosening the screws and pulling it down. IF your concerned much w/ speed tho id suggest a gps.

    I kind of want to lower the wheel but I'm scared I'm going to mess something up. So, my readings sound about right?

    i think your good Allen. rpm's sound right. and if your ski is getting a good holeshot you will know it.

    no use lowering the wheel if you dont have a gps to compare it to.
