    2001 gp1200r

    I'm rookie first time owner of a ski. I was wondering if anyone could tell me how to fix or help the low speed wobble ? After planing out going around 15 to 20 it wobbles left and right when I speed up it goes away.

    Welcome rwellsauto..
    do a search on "chine walk" or "gpr happy dance". this should get you started with a few ideas on what's going on and a few steps that others claim helped them.

    That's the cure, "speed up"...it stops doing the "GPR happy dance" around 30+.
    Do a search for 'stepping' the sponsons, that will help a little and something you need to do anyway. It won't stop the 'happy dance' though, speeding up to 30+ is when it settles down.
    It 'is' a GPR after all...open that thing up and have some fun!

    Hello and welcome to the Hulk. I have two GPRs and they both do the famed "Happy Dance", I have come to enjoy it. It is kinda nice just to gently rock from side to side and enjoy the ride. Have fun

    Improves handling and tracking. Again, "Do a search for 'stepping' the sponsons."..."stepping gpr sponsons"...and you will find abundant info.
    Since you're new, here ya go...spoon fed links.

    As suggested, putting "gpr happy dance" into the search function will get you some more info specific to the GPR.

    There are always engineering sacrifices that need to be made when designing cars, watercraft, motorcycles, etc. You cannot have a vehicle that has excellent towing capacity like a diesel rig, that rides like a cadillac, with the fuel economy of a Honda civic and accellerates and handles like a motorcycle. Something must be sacrificed to gain something else.

    A Yamaha Blaster I was designed to ride like a motorcycle, but it is so unstable, just sitting on it is a chore for some folks. Some cannot even get on it in deep water! A sacrifice of low speed stability and high speed for great turning ability.

    A Yamaha Raider was designed for a great top end in straight line riding (for its engine size), but you can seriously hurt yourself at high speed in rough water because it had a bad tendency to dart left or right once you launch from a wave....... No handleing for great straight line speed.

    Cigarette boats chine walk at low speeds. They were not designed for low speeds.

    The GPR is a performance craft that does not like low speeds either. Chine walking is a small price to pay for all of the great things that it was designed to do.

    Who rides a GPR 20 mph anyway? It is like buying a Camero to go to Sunday church.

    Well I ride it because it was given to me.. We like to go fast, but as I said I have never owned a ski and just thought something was wrong with it. But thanks for the lesson on engineering.
