I need convincing
TailTwister,
You have been given some excellent arguments in favor of four-bangers by some very knowledgeable folks. But, judging from your last post, it seems to me you have your mind already made up in favor of a two-stroke. Hey, that's okay.
If you're looking for best power-to-weight, get a two-stroke. If you're looking for least maintenance, get a two-stroke. If you're looking for noise, get a two-stroke. If you're using a pipe on a two-stroke, have fun tuning it.
There is more to four-strokes than simple apple/orange comparisons. Four-strokes have an ambiance, an aura of cool, if you will. Those who are simply interested in price/performance would not understand.
