buy a husquvarna - just to be different.
shame about the triple, I always liked those bikes. I know you said it was slower than your (modded) RD400, but really was it all that bad? Honestly if it wasn't that nice I would say make a trial bike out of it, lots of the 70's kawi trail bikes used triple cylinders and heads anyway.
Really though, I think your next two stroke needs to be an h2.
