RXP-X Riva Ride Plate Buck Problem
I recently install JD1 open loop and Riva ride plate and now regurlarly experience bucking. The buck occurrs when I chop the throttle at speeds over 74 mph. I have seen reccomendations to install pump relief but can't find a system to purchase. Recently contacted JD1 and he said that his system can't prevent the buck with Riva ride plate on P-X. He also said his pump relief system is now delayed and would not be available for awhile.
My question is there anyone who has found a pump relief solution for Riva rideplate on P-X?
Other handling mods are Riva pump extension and RE block-off's

I'm sorry to hear that man. I've heard that's why Riva doesn't push past Stage I on their RXP-X platforms as its too easy to induce buck, especially by adding lift. I have an RXP-X and I am being careful not to add lift when trying to add speed on mine for that exact reason. You might contact forum member Duke as I know he has done some work in this area before. Also, the R&D grate supposedly removes the buck up to 80 MPH on stock rideplate skis. It might help in your situation, but I don't have any experience with it. Good luck and be careful.

I thought people were warned not to use the RIVA open loop plate on the PX. Atleast I saw that warning right here on GH.
I don't know what intake grate you are running. I don't think the pump ext or RE BOs are helping you any either.

The bucking I experience is like running over a log at high speed. The nose goes down and back of ski jumps up which causes a sudden decelaration. The back of ski can also kick slightly to the right. At 74 mph I can stay on the ski but my chest slams against the handlebar cross bar. What really concerns me is if this happens riding two up.

There is a warning using the Riva rideplate with P-X but the warning states that you must use a pump relief system. Problem is that I cannot find a pump relief system to install.

If you ease off the throttle instead of "chopping it"--it should not buck. This will hold true if it only bucks when you chop it. I am n ot sayin g it wont buck in the upper 70s while on WOT. Some do and some dont at 77 and above.
