I am not too worried about them. The thing that bothers me is that in 5 years or so we might not see the two strokes due to regulations.
My question is this. If the factories put the same kind of energy they are spending making the new 4 strokes into a new clean burn two stroke design, would'nt we be miles ahead?
Eric, given a large enough budget, could someone like yourself design a two stroke that performs like we know them, without the emissions problems?
