    Re: Jdpilot- Backup/spare/copper x2 refresh build

    Suncoast used to advertise these in PWI in the mid to late 90's. Not sure if I could find an ad, will look at the issues I still have... Always thought this was a cool idea.

    Jack,
    You should be able to make one using a stainless steel pneumatic cylinder. There are other brands, but this reminds me of a Bimba cylinder.

    Jdpilot,
    Are there any markings on the other side of the cylinder, or do you have the OD of it?
    These are pretty modular, once you know the bore and stroke of the cylinder, you'd be off & running. You could even make a "hydraulic trim" setup with a handlebar mounted valve that lets water in & out of the cylinder. With the valve closed, the nozzle would remain stationary regardless of throttle

    Updating the ongoing (loooong and sloooow) build thread. After head install above, I reaped 45.1 on the Garmin. Added a bored group k Nozzle today and an aluminum impeller boot to smooth out the flow. New GPS results coming this weekend. Not expecting much, but curious nonetheless.,
