2002 Polaris Virage top speed/rpm seems low
Glassed river. Wide open throttle. 6000 rpm is where I top out, and 42 mph. Does this seem normal? From what I read, 6500 should be what I am seeing, and closer to 50mph.
I have the ski running smooth. Good compression. Throttle plate is fully opening. New 6 vane ss stator.
Prop is stock, but showed a little wear and light knicks. Did not check the prop to wear gap yet. What should it be and what else can I check for?

Have you checked out the fuel system? Cleaned or rebuilt the carbs?

I have rebuilt the carbs and the gray tempo lines were swapped out last year.
As a history, I go this ski in a trade. The previous owner was a PWC tech and had just dropped in a new engine due to hydro lock. He got it off a pissed off customer. He also rebuilt the carb.
I got it and finished bolting it all back together. It ran, but rough. Also had hit and miss ignition. New cdi fixed that.
Due to the low speed I tore into the jet pump and found massive stator damage. It was the 5 vane alum one, so I upgraded to ss 6 vane.
I kept having fuel issues so I rebuilt the carbs again and upon finding green trash, I gutted the fuel lines and went all new.
After everything, I have never gotten it above 45mph. Gaining on it little by little, but not there yet. I will take the plugs out today and post pics. Just put 75 miles on it at the river so maybe we can get a good read on them.

Correct spark plugs?
Spark plug wires and ignition coil ohms correct?
Ignition timing correct?
Fuel selector valve air tight under suction?

Plugs are correct. Wires and coils ohm out in spec. Timing was good, but worth another check.
Not sure on the fuel selector. How can I tell?

Easiest way is to install a new one. They can be rebuilt, but new doesn't cost that much.
Watcon sells generic replacements, I think.
