04 RXP turns 5700RPMS today, help needed?
Put some new gas in it this spring, just took it out for a quick run, about half old gas, half new gas, turned 5700 RPMS, and sounds like a diesel running. New plugs needed? WHat type, what oil also, and how do you change the oil? Im a newb to it.

Lets eliminate bad plugs by putting in some new ones.
Check the pump, and make sure that you do not have debris in the pump area.
Next, do you hear the supercharger whining when you rev it?
If you do not, take the intake for the supercharger off (The front hose on the supercharger), and try to spin the impeller. If you can spin it easily, you have almost certainly grenaded the washers into your engine.
You are at the RPM level where motors tend to run when the SC washers grenaded......
check those things and get back to us........

Great then I just got scammed on this machine if its the washers............

When the washers go it typically revs to 64-6500 but it runs well. More than likely the plugs just need to be changed.
BUT, do as Jeff says and check the S/C impeller by pulling off the hose.
And if the washers are good, and the plugs take care of the issue, order metal washers for it right away...dont gamble

Got ya, pulled the plugs and they look OLD, even had some rust colring on the white top of the plug, I hope its just them, what gap do they need to be at? Do they need to be prepped before installed?

I had a simular problem, bad fuel. Change plugs, Drain as much of the old fuel as you can and refill with fresh. Remove filler neck from tank and siphon out. Take the hose off the supercharger housing and see if the sc wheel has tension on it. If it spins then washers are gone.
