    Note what your top RPM's are now. Then to check the RAVE Valves, remove the springs from inside the RAVE Valve caps (black and red caps), replace the caps and run your ski without the springs. Your ski will be doggy on the bottom end, but if the rpms increase substantially with the springs removed you have a RAVE Valve issue.

    Drill holes in the caps. That way you can watch them open. They do not hold pressure.

    Take off the caps/springs then start the ski on the hose, work the throttle & watch the raves go up and down, shouldn't take but 15-30 seconds.
