Still have a performance prob with 00 XP
All last summer we tried to figure out a problem with the rebuilt 951 in my 00 XP.
It is just like the TPS is not working. We get to 6K rev's and that is it maybe 6300 about 45-50 mph.
Now every now and then all of a sudden the rave open all the way and pow full rpm's.
We have a new rebuild motor from Water Worx in Florida
A new MPEM
Checked the TPS and it does the 5 volt thing right where it should.
We cleaned the rave for good measure and best we can tell the exhaust rave like valve is working since it does allow every now and then the motor to full rev's.

Take the rave caps completely and remove the springs too. Take the ski for a spin without the parts on the motor. Will be a turd on the bottom end, but still should hit 6800+ rpm

Yes, check valve on RAVES is probably frozen, not allowing the RAVES to open. 6300 is the majic max rpm number when they aren't opening.

Check the check valve going to the solenoid from the case. I have a similar problem and my check valve is stuck closed not allowing pressure to the rave solenoid which in turn opens the rave. Almost the same symptoms.

I had an 01 that did what sounds to be the same as your problem and on mine it was in the mpem plug where the tps wires enter the mpem, inside the plug the female end had slipped back into the plug slightly and sometimes the plug would make contact reaching max revs, worth a look

i 6th raves - you should be able to check the solenoid with a low pressure gauge like 30 psi mikuni pop off tester.
here is tps test info for those that might happen upon this thread in a search
