Why do the exhausts taper to tiny whistles? I get that a 2 stroke needs the backpressure but aren't you limiting most of your power away with such drastic taper?

    The smaller it is, the more power, and the sooner you melt the piston from the retained heat/pressure.

    Don't think of two stokes as three simple moving parts, they are one almighty pipe and a not that important engine.
