What would you do next.
I have 00 XP that will be getting rebuilt soon:
Pro X .5mm Pistons
Rossier Pump gas Head
Proks and outterwears
Rossier jet kit
Everything else is stock.
Is the stock prop a good one to stay with? I rec ride, but dont mint paying for a prop that will benifit me.
Was turning 7000 rpms before rebuild with only 135 PSI on both cylinders
Anything i can add to have a little more?
Impeller, Impelle grate, ride plate? Nozzles, Pipes, Water regulator?
Hows that one?

You did the biggest bang for the buck mods, and from what I've read, for a mild ski sending your stock prop to impeller pros for a repitch is ideal. Did the Rossier jet kit come with instructions and settings? IMHO everything has a balance point and why spend ridiculous sums when you can just grab rxp for almost what it would cost you in upgrades, more or less
If you really want to spend heres the ski to buy, the guy is over in the yami forums;

Try to get hold of a 97.5 manifold and pipe will give you 100-150 rpm on top. Install a set of rinnaldi reeds,have the pto machined down to the diameter of the coupler,lightened flywheel,stock prop welded to outer edges of blades then machined back and re pitched,Stock prop can be scalloped out on the backside of the blades to give better drive,ditch the rossier jet kit and go more conventional,water inject these pipes (dump lots of water) about 3 inches from the manifold joint and the increased torque will put a smile on your face.Then you have to start machining internal parts to get better gains other than pipes and carbs. The exhaust ports can be machined back almost 3 mm to give better torque.Advance the ignition timing 2 degrees but will have to run premium fuel after.

What do you thinks not good about it?
145 main mag
115 gram springs
1-1/4 turn out on high speed needles
1-1/4 out on lows
22 PSI pop off.
I already have to run 93 with the rossier head. You dont think advancing timing plus running 160-170 ish compression would be to much?
