About 2 vs. 4 stroke motorcycles....

Not true! Most motorcycle engines are now going 4-cycle, at least for
the street. Even diehard fin-ringing, blue-smoking manufacturers like
Kawasaki and Susuki (anybody remember "Ram Air Cooling"?) have all
converted to 4-cycle engines.

I think the real reasons for 1hp/cc in bikes are:
	1 - Peakier power curves on bikes than cars.
	2 - Less durablility in bike engine designs than cars (they run
	    closer to the "hairy edge").
	3 - Less pollution control as a whole for bikes than cars.
	4 - Much more attention is paid to breathing, scavenging, etc.
	    in bikes than cars.
	4 - ?
