    non pv cylinders

    Has anyone built a EFI 1390 Lowell with the later non pv cylinders? I was just wondering how they pulled without valves altogether.

    I have had trouble with all the valves available including pinned stock ones. This GPR has been cursed from the start.....

    Gas valves transition through their range with the rpms. A much smoother hardly noticeable transition. The electric valves are digital they are either open or closed. I do get a kick out of when they open feels like you just changed gears.
