    Getting rid of the 30 mph bounce on GPR ?

    Has anyone been able to get rid of the annoying bounce between 30 and 40 mph ? Between 0 and 30 and 40 to 80+ I have absolutely no bounce.

    Currently using 1200 grate and Jims FF Plate with tabs pushed down with two washers. Did not help when I pushed the tabs down even further.

    I have a slight bounce at a different speed. 40-48...

    I didn`t have this before with the stock plate and set up. I have my IR plate set up modestly and tabs down .060. I just think it is a characteristic of these changes...

    my sponsons are staggered.

    my ski is pretty damn smooth thru the entire range. I have my jims ff plate set up and my factory tabs are shimmed down evenly

    Yep still bounced only there between 30 and 40. I think it is where it comes on and off the keel ? Would be different for everybody depending on the angle of the plate.

    its the GPR happy dance...

    the only way to get rid of it is to push the tabs and plate down, but then you lose speed

    stepped stock sponsons help the most to control it... most aftermarket sponsons make it worse (but turn better)

    they all do it

    +1, she is letting you know she is happy. All happy GPR's do it. She's letting you know she is rarin' to go



    Mine does it. Snap the throttle and let her go faster, it'll line her attitude out
