    Thumbs up Everyone Please post one Speed Trick

    I would like every forum member that has good speed information to post at least one good trick that they know works as a gift for other forum readers to share. Please everyone only post good true information no junk. Here is my trick > When you have your pump shoe out bolt the intake grate to the shoe and match the grate to the shoe by grinding the shoe and grate till they match exactly on the inside as well as under side. The fit of the grate to the shoe is very bad. I also do a second grate (Spare) Since a purfect match can't be done once the shoe has been sealed in. Also when sealing the shoe and transom plate in I use muratic acid to ecth plate and shoe so the sealer will stick to both good. The proper sealing of the shoe and transom plate is a must for a super fast ski. I know some people have done what the thought was a good job but i supect they have a bad job that costing them speed! Merry Christmas to all!

    I like to fill the little holes on the inside of the stock sponsons. Not sure how much it helps, but I figure it can't hurt.

    Filling the pump shoe bolt holes with epoxy putty is good for .5mph.

    If your confident with your combo the rideplate bolts are worth a
    little more.

    Good post, we're all hungry for speed secrets

    I angle my handle bars back so I can hang my short legs off the back of the ski more in super man position Hey every tenth adds up.

    Try different octane. I tried 89, 91, and 93...mine runs the best with 91.

    also...when Im in okoboji, Iowa, I fill 2X 5 gallon tanks with 91 octang of their fuel because there is no ethonal in it. Runs faster with that fuel than it does with minnesota fuel. Haha, funny but true.

    frontal area

    not quite an unheard speed secret... but we dont metion it with ski's as much as i would think!!
    Frontal area... ,dirty skis, mirrors, scoops, loose ropes, loose flaping clothing... any thing that will give you a larger frontal area will slow you down.( now,i dont want to see any shaved head's at mb3, but anything done may give you an edge) think speed skaters, swimmers, motorbike racer's, cycleist's.....they cut off seconds and energy spent with this thinking .
    Get YOURSELF tucked in and tight,with those canted legs in and if needed, a narrower seat to enable you to do it...

    The best known secret for GPR speed here is www.greenhulk.net it seems to be good for 0 - 30 MPH. More when you try the search feature.

    Thanx for all the work & info here. I'm new to the GPR and you guys have been great.
