    The 81mm ring has proven ideal, but make sure you get 8100 RPMs.

    What should I use if I am not turning 8100 RPMs?

    This could be a really dumb question ... but is there a way you can run a 81mm ring on the stock nozzle, or do you need to run a Riva nozzle or something like that which fits the different size rings?

    I sent my stock nozzle off and had it machined out to fit the different size rings.

    STSPERFORMANCE can machine your stock nozzle to accept the rings. The riva nozzle is nothing more than a modified stock nozzle.

    look him up, he is a member on here and his name is Steve. I am having him do mine next week. He also does some other cool stuff like gauge pods that fit in your mirrors.

    It depends on what your RPMs are at now. You can either bend the trailing edge of your prop blades (1mm = 100 RPM and so on) or you can change the nozzle size (1mm = 60-120 RPM -- it varies from ski to ski)..
