Did I miss anything ? Winter mods
Wanted to make sure I have eveything covered before spring comes along. Looking to be high 60's with very strong acceleration.
Ski = 2001 GPR - It had nothing more than a 13/19 and Riva Plate,Tabs,1200 Grate
This winter I picked up
Angled Riva plate (no skegs) and Stock plate (sometimes I am on Lake Mi where the stock plate should work well).
05 Pump with 14/20 Dynafly and 85mm nozzle (praying I can turn it).
Decked stock head (150 lbs)
Pump Plug Kit
Carbs proffesionally rebuit 110pilot 120main 95g spring and acc pump disabled.
VFIII reeds on the way soon.

I dont see a grate mentioned anywhere but this would be the first thing I would have done. Other than that your list looks good.

You should beable to turn the 14/20.
On my stock more 1300r I was able to turn it right after a rebuild, during break in it was pulling 6900 rpms.
But those 14/20s are hit and miss.
Anyways, if you havent heard about Jims new rideplate mod you should check it out. It is called the FF mod, you will gain i believe 1-2 mph over his j plate.

I would consider 3 degree keyway or Advent ignition (84 curve) if strong acceleration is what you after. Made a huge difference for me. Riva 1200 grate too.
120m jet seems a little low to me, maybe 125 to start with being in IL..

I do have a 1200 grate also thanks guys.
Duke, With the advent I was concerened with fuel...Do not want to run anything more than 93

Duke, good catch, I forgot about the keyway. Keyway is much cheaper than the Advent.

Maybe flame arrestors would help increse HP to pull the prop better, I have a set of Pro-Tec Moflows for sale right now. My '01 with nearly identical mods pulled 74.5 to 75.5 (once properly set up). Did my own rideplate mods and intake grate mod to a 800 grate so it kept the speed but didn't cavitate out of the hole. With the old 13/19 and a good rideplate I thing 70 would be a given.
