    Cant see that mentioned anywhere in the detail.

    Would be interesting if they plan to support the other Bosch ECU's skis as that expands their market hugely.

    1500 / 1630 head & cam differences )))))

    Can anyone advise if these are interchangeable?

    I have been advised that a cam from a 1630 will fit a 1500 (would obviously need tuning correctly) - can anyone confirm?

    Likewise for retainers?...

    Stock Spark 90hp should do 50-51mph at 8000-8100rpm.

    It will vary depending on your air temp and elevation.

    A reflash and a 12/14 will see 53-55mph at 8500ish rpm.

    I think they're missing a trick with the stand-up market.
    They have the engine and pump and could easily make a plastic hull.
