I have more 2 strokes than 4 strokes, my most interesting rides are two strokes. I think there is a point where it ends up less expensive to keep up with the 'racer' crowd building a banshee.
I've seen some cool stuff come out of the experimental garage, low budget hot running stuff. A stock bore raptor, stock piston, mystery cam ground specifically for this motor. Stock carbs, no main jets, running methanol and warrior shocks, killing OOF 8" swinger banshees. It was fun to see them ride by and stare at it. Didn't look good, but the right guy on it and it ran pretty good.
