ski is unstable at full throttle

my 91 sj with 701 twin carb engine bounces around heaps when the speed increases any ideas??

Got an intake grate on it?

haha yeah, hang on, bend your knees and bust out the poo stance!

what type of ride plate?

Iv ridin your ski and personally believe it decends many years ago from a small family of kangaroos... adjust ur poo stance! :lol:

could always try my ride plate... not like my skis going anywhere in a hurry ...

its got a standard ride plate which has been extended

with a homemade d cut like the worx dominator plates. also yes it has intake similar to a worx maxiloader.

I still think it's because it decends from the kangaroo family.....

as Norm said
what intake grate do you have in it
you may be unloading the pump at speed casuing it to bounce around
