    What if it's timed to run counter clockwise (from the front). Would that work with reversed heads, pistons and a stock cam?

    I was thinking about that too, but you'd need to find a way to move the timing chain tensioner to the other side as well as modify the oil pump so it doesn't pump oil in the wrong direction. In a motorcycle application there's also the issue that you'd be spinning your wheel in the wrong direction also. It'd probably be easier to make a cam than overcome all the rest of that.

    I was wondering about the oil pump too, but with it's rotary design, it doesn't seem like it would matter which way it was spinning. Maybe I'm wrong there. Seems like a simple adapter could be made to reverse the chain tensioner. Maybe this would have an application for mounting an airhead motor and 5 speed tranny on a "backward drive" Ural.

    So much easier with a two stroke!:lol3
    I had a Bultaco Trials bike that would run backwards all the time. Just lug it a bit with the clutch at idle, and it would kick right around, and run like a dream. Threw me over the bars a couple times:D
