Ditch the R&D plate and put a VX plate on it, depitch prop open up nozzle for more rpms..... Or for ocean riding put stock plate with Jim's mod

I de pitched the Solas down to 18. Open your nozzle to 86mm. You will be over 82 likely with just that

Check out my build thread in my sig. A lot of testing and tuning has been documented.
If it were me...
Pump tunnel reinforcement before anything!!!!
Get rid of the R&D ride plate and have the stock one modified by Jim.
Get the R 3 flash or R4 for even more power with 8800 rpm limiter.
Get Riva retainers and use stock valvetrain
Riva cam gears
Pre 2014 Exhaust cam
Rising rate regulator setup
Either pitch impeller accordingly or get another one that fits your build and spin it to about 8600 rpm which is safe for those skis.
With that you should be at about 86 mph.

You are almost there just a little more tuning and make these few changes
send prop to Jims performance and pitch to 13/18
also have him mod your stock plate you can shim based on your conditions in smooth water I only use shim in the front
get the R3 reflash you can leave the limiter at 8650
i I just did these same mods and most of what you already have on a 14 FZR and the ski runs 84 with the 13/18 prop you can change the nozzle to a 87 if In the summer you need to get some rpms back my target rpm is around 8450

thanks man. About the prop, I have to send the stock one or the solas to get pitch? Thanks
