Riva Plate Bouncing
Just trying to tune my setup and im running about 84 mph at the moment but the ski has a bounce to it at these speeds and no matter where the VTS is positioned it still does it.
When riding two up it is no problem and can watch the gps and im doing over 82 MPH with both of us on it.
Im running the Riva Block offs, Riva Grate and Riva Rideplate.
I have'nt trued my grate or filled the holes yet.
Will a pump EXT help this?
Should i place some 0.020 shims under the back of the plate?

Rick, start by putting some .020 washers under the back of the plate. If that doesn't cure it try some .030

Absolutley love the handling in this plate. Recommended as first mod to do IMO.

How does your ski turn at high speeds with the riva plate

Yeah mate i love it.
Its almost like having a really good set of sponsons.
The turning is quite progressive.
You turn the bars a little bit and it doesnt do much then turn a bit more and it bites in hard.
If your not being careful it will bite so hard you can be thrown off. Got to hang on tight.
Im running stock sponsons untouched and i would think you would never need sponsons with this plate.
Also i run the trim about 1 bar above neutral and you never need to drop the nozzle when coming up to marker like you do with the stock plate. There is just no chance that this plate is going to spin out.

mine only bounces ..when i am below 1/4 tank.just stay more forward when low on fuel.it will get progressively worse until you move forward and let out ..that is why it doesnt bounce 2 up
as for the plate not turning ...at speed..if i have it trimmed above netral... i agree.. it is about the same as running skegs...i run the rivers ..trim at netral and it works well.. you can modulate it well ..anymore down and it can be a little to agressive..especially if i have the girlfriend on the back ..solo it is ok
i also have my stock sponsons lowered ..and an r&d autodrop nozzle...so my ski has allways turned hard.. on the tighter stuff i have a tendancy to come in hard kinda pitch the ski in sidewase to slow it ..then when it bites ..cut it hard..and nail it out ..
i also really like the way it tracks through the chop ..

Dont add shims gust remove the riva grate and put r&d grate you will be good up to 87 mile
