My First (Running) GP1200R
Earlier this year I got the GPR bug and sold my two Polaris skis and bought 3 non-running GP1200R skis. Tonight will be my second time out as the first time was a bust b/cmy fuel flapper was warped and I had no fuel pressure.
Do yourself a favor and add these to your must do list whenever you get a GPR
1) Replace Fuel Filter
2) Clean and or Replace Carb Filters
3) Remove the fuel flapper and screen
Now for the mods/replaced parts
ADA head with 40cc domes
Waveeater clips and couplers
New crank seals (Held 10PSI for 3.5 hours)
D-plate with sensor chip
Riva free flow tube (Blue)
Hole shot kit (Fercho Style)
Hole shot kit relocation
SS hole shot gasket (This was a GREAT idea)
Complete carburetor rebuild (OEM Only)
Drilled out returns
90 installed into return fitting on sending unit (Great idea from WFO)
Accelerator Pump Removal
Rejetted for all mods and adjustments
Fuel filter replaced (A MUST DO)
Fuel Flapper/Screen removal (A MUST DO)
Selector switch removal
Solas impeller 13/19
Bilge line removed
R&D 1200 Intake Grate
Pump shoe Polished
Pump shoe sealed
Coco's reenforcement kit
2004+ rideplate and pump shoe brackets
500 gph rule bilge
1300R fuel selector plug
1300R Choke removal plug
PET-2100DX installed in glove box
In addition to the above mods/changes, I stripped down the entire ski to the rivets and cleaned, replaced, or repaired as required every part I touched.
This was alot of fun and I owe so much to the members here that have been so helpful. Just to name a few and in NO particular order
1) Crashhard (Joe)
2) Osidebill (Bill)
3) WFO (Rich)
4) Lhorning (Lowell)
5) The individual who shall remain nameless who provided me with a manual
I think that is everything...... If I remember anything else I will post it here. I have two more skis to do so next time I will try to take more pics during the process. If you see something I missed or did incorrectly please post it here.
Now on to the pics!!!!!!!
Rideplate and Shoe
The remaining parts

That is very Very NICE. Quality workmanship, with some really nice, neat finishing touches. A credit to you. Wish the Yami Stealers could take a look at what quality work looks like! Hope you get many fun hours for all your dedication and attention to detail. Regards, Dave.

Thank You for the kind words...... I will try to dig up some before pics once I warm up from my trip to the lake tonight.
My second time out was much better than my first
I went to Buck Creek State Park (Ohio) and had a blast.
52 degrees ambient temp with 58 degree water, 20 MPH winds and no sun to speak of.
Top Speed was 65 per dream-o-meter @ 7090 per PET-2100DX
Compression after 45 minutes was Mag/Center/PTO 127/125/123 (Same as before)
All plugs were coffee color and moist
I estimate that I used 5 gallons of fuel in 45 minutes with an average throttle position of 80%. In other words the only time I let off the throttle was to turn around.
Given my RPM, Plug condition, and fuel consumption I would say I am running rich. However until I get used to the ski I will leave it that way.
These are very fun to ride and stick very well to the water. I tried to slide it through a turn like my SLX 1050 and almost bit the dust.
Please let me know if I missed any mods, I tried to do all the ones I could while leaving the engine in stock form. I have a HO pump sitting on the work bench waiting to some attention and I know I need to get Jim's plate and Leo's hole shot kit. Other than that I think I covered all the bases.
See you out there......

Nice looking ski, now onto your request.
I would dump the #3 cooling line overboard and run the #1 into the exhaust manifold and lose the tee.

Yes, that is a clean ski!! I think the white and silver GPR's are the best looking of all years.

That is the cleanest ski I have seen on this entire forum. Its a 2000, and it looks like it was just taken out of the crate at the dealer.
