Re: 2-stroke + 2-stroke = 4-stroke!
Me, I think it's a "comfort zone" thing. I've worked a lot on two-smokers and could probably do it in my sleep by now. I'm sure I could manage on a four stroke, but I also like how the China Girls look in a bike frame - so I'll bet that's part of it too.
I'm not exactly a fanatic about two-strokes. I don't pretend they're any better than fours. I think you can put down some money and get a good engine of either kind. The cheaper you go, the more sacrifices you make. That's true whether you buy two-stroke, four-stroke, turbine, Wankel rotary, Stirling, pulse jet, 3-stage steam, whatever...
