loss in rpm problem
2007 rxp s3 supercharger, 14/19r, stock intercooler. i was running 8100-8120 rpms now it acts like it is pulling timing or something and will only run 7800-7980 rpms. didn't know where to start looking for the problem. bad gas, supercharger slipping.... any ideas?

CHeck / replace spark plugs. Change oil and filter (at least make
sure level is where it's supposed to be).
Check s/c to throttle body air hose.
Try different premium fuel without ethanol.
Which spark plugs are you using?? Will need 1 step colder
plug with the S3 Charger. (ie denso ixu 27)
Inspect wear ring and prop for damage or debris

it sounds like it is skipping when you ride it at part throttle or full throttle

Thes skis are very sensative to weather changes and crappy fuel. I have seen where skis with old fuel will lose a couple hundred rpms do to the exu pulling timing from bad fuel. I have also been out riding after it had rained and lost a couple hundred rpms. I could actualy feel it surging as I went through patches of fog. The other 2 skis that were with me noticed the same thing.
