    1/4-turn or Motion-Pro Revolver throttle

    I'm running a set of 29mm Keihin CRs on my GS1000 race bike. The carbs have a push-pull throttle setup.

    I'm interested in going to a 1/4-turn throttle, or in using one of the Motion-Pro "Revolver" setups.

    I'm wondering if anyone has fit one of these throttles to their CRs?

    Motion-Pro said that they could custom-build one for me. I might do that, but at nearly $200 shipped I've got to first ask if there's an off-the-shelf kit for another bike that'd work just as well.

    Any suggestions appreciated.

    Thanks, Patrick

          Any mod that does for 39 cents what a $200 Motion Pro product can do is a good mod.

            Why do I get the idea, someone to the notion of ideal simplicity and turned it into a convoluted notion of need for $150?. I guess that is marketing for you. Guy must be a genius (the other guy).
