    Valve shims?

    With the valve shims is it still safe on a 08 motor to run 8650 rev limiter that the Riva ECU has???

    I don't think that anyone recommends just the shims. Most recommend either Rotax Racing Shims and light weight retainer set or the SeaDoo Centre lightweight retainers. You could also do the Riva valve train kit as well.

    Get the seadoo centre retainers they are good to 8650. If you add light valves then you can go to 9000. R88
