Re: 2 vs. 4 Stroke...
I wasn't saying that a 4 stroke was better for a bike, in fact I'd rather have (and do have) a 2 stroke. It's smaller, cheaper, lighter, more powerful and looks better than the 4 stroke, and the slightly higher fuel consumption is pretty much a non issue. In my original post I was talking about the advantages and disadvantages on 2 vs 4 strokes in general. They each have their place for different applications, where power to weight ratio is more important than fuel consumption, emissions, and longevity the 2 stroke wins.
