    To be safe you can go riva valve train upgrade but les cooke retainer are good for 8600 also!!! Very good. Only adviceyou to take off throttle when the ski jump on waves othervise you can destroy inside!! But if you use les cooke retainer with this advice , you will never have probs!!

    You do lose about 100-200 rpms with the Riva valvetrain but then again you are buying security here. The Riva valvtrain has been proven to be good up to 9,000+ rpms. How many rpms do you think you spin when you come unhooked?

    Many have had success with just retainers but I've also seen many failures happen. None to this date with a Riva valvetrain...so I would go the proven route and stick with the Riva valvetrain.

    Orlando is just right!!!
    I preffer the safest way on my skis so I put the riva kit!!!
    Think it from the other side:
    Riva kit 600$ new!
    Damaged engine(Head-valves-pistons-etc.....)4000$

    Personally I use Les' retainers, but Riva also sells just the retainers instead of their entire kit
