    Cool GPR Holeshot modification

    Want to install the jetworks kit, for better holeshot, but i`m afrraid the spring-valve may be clogged up.


    I'm thinking of a large, smooth working ball-valve connected to the PV servo, so it will open on higher RPM's, to cool the waterbox.


    What do you think? Please let me know if it's worth trying, and i'll be the first to test it, and post all results.

    I believe the power valves open at a higher rpm than you would want for water cooling to start.

    Keep it simple. Don't over engineer it.

    Seems to be a bad idea!

    Powervalves open too late, so the waterbox and exhaust will be cooked!
    Stopped this project and go with the jetworks valve, no faillures of the valve known to this point.
