Well, I already have a larger exhaust header and a Supertrapp muffler and I started it up with the new carburetor I bought from Honda for my xr200.
The plan is to leave it stock for now, but eventually I'd like to put the 247 cylinder on it and see if a Torker 2.0 camshaft will fit or if I can get one ground by WEB. We enjoy building these little motors as much as riding them. From what I can see there is no reason these cannot be built in similar fashion to a Japanese motor.
The new camshafts available for the 230 and 200 series really wake these little motors up; the 89a cam in my 200 didn't hurt bottom end at all, but gave me a nice boost through the mid-range and much more pleasant over-rev.
