    I had a go on a can-am in the late 80's. Magical levitating front wheel. Just like the Japanese competition.
    They were doing some cicuit racing with tandem twins and not getting humiliated.

    I rode a Can-Am ASE enduro bike back around 1985 when they had just come out.....
    It was rough around the edges compared to the Japanese offerings......but it was a brute when you would twist the wick....raw,unrefined power.

    D*mn.....I miss the 80's .....good times,good times.

    Huh, apparently the PattOP engine really does run well.

    I hear it has head-snapping torque.

    Breakneck speed, I'd say. Google pattakos flyer for more information.

    It does indeed run for a few seconds with no load on the bench. Maybe it can run longer and with a load, too!

    A six cylinder radial scuderi engine might not suck.
    Need valves on the power cylinders but the cams can be on the crank.
    Power wouldn't be any better than a 4 stroke radial with the same number of cylinders, but it's a lot fewer parts. Plus you gotta love the lightness of a single-throw crank.
