    Yep. Some bounce is okay, but you want to make sure you don't open up the window on the bottom (intake) and bring in a buck without enough shim.

    I have 2 washers in each side amounting to something like .160 inch
    I tried .06 and .09 and almost got thrown off each time. I was never able to get over about 74 until I added the .160 so I have no idea what I might have lost. For me I guess I added speed since I could stay on.

    Thinking of shimming the grate which should be interesting.

    Good time to chim in...I've bucked with shims.

    Solution: put pressure relief valves in and take the damn shims out. I do bounce in flat straight line water, hell I bounce with the stock plate. Jim's plate is fun and I'm running 71 in the heat. Not a good plate for the chop -- it loosens the ski up too much and you unhook.

    I have to thank Jim's Performance and Team Tampa for the install and the results.

    So the pressure valves took care of your bouncing?

    Hey Andy...read the post again. "I do bounce..."

    Since I put the pressure relief valves in...I don't buck and no shims.

    Well, I'm just doing the math and see that I could add two more shims (actually 3/8" SS washers--.046" each) and that would only be at .138"...

    Wonder what that would do to an FZS?
