RXT 215 lacks power , Wont run over 50MPH. Suggestions?
Have a 2005 RXT, The ski has a ruff idle when cold, once it warms up it smooths out. Idles at 1700RPM. Ski is very sluggish on take off then I can feel the supercharger kick in. Ive done all the obvious to the ski. Ski DOES have riva washers and the SC is working. Checked boot from charger to T-body, nice and tight. Swells up when reved.
*Just installed brand new Riva stainless wear ring. Helped top speed a bit.
It almost seems to me like its not running on all cylinders. Plugs all look nice a choc brown. Good compression.
Can a coil or injector cause this?
Any other ideas I can check into ?
Any help would be great guys!!

Change your plugs, mine had the exact same symptoms 2 weeks ago. New plugs and all is well.

Yes I did change the plugs, they are brand new.
I did just pull the intake boot (from charger to Throttle body.) There is alot of grease/oil in the boot and the Tbody. I will clean this out tonight. Doubt this is the issue though...

front seal on the sc might be leaking oil which could foul the plugs

Could be, but I just checked the new plugs and they still look brand new, just white on the tips and wiped right off.... Could the oil have clogged somthing in the intake manifold/intercooler to cause this you think?

What rpms are you maxing out at?
Who installed the Riva washers in the SC?

Im not sure of WOT RPM's. I will put it in the water and check today. Jerry (greenhulk) did the washers for me. It ran great all last summer after he did it.
Im thinking maybe an injector one one of the cylinders is bad, or a coil. I just ordered both to see if I can swap the new ones on each cylinder thursday to see if I can solve this..
