The simple answer to both of those, is no.

The easiest to explain are the pipes. Just get some NSR250 pipes. TYGAs would be the easiest option, if you want new, and certainly the best performance-per-pound/dollar/baht/sheckle or whatever other currency you may work in!

The best NSR we've ever run was using DogFights. You can still get them new from Japan, but you really have to pay through the nose for the pleasure, especially if you want stainless/carbon. There are several kinds of Jha pipe... some work better than others, and the differences are quite striking! Once upon a time, I would've sworn by them, but not after 1000s of dyno runs over the last 10 years.

As for the rotor, you'll need to look into that once you really know what you are doing with the motor. IF you find a good HRC crank, then no, an MC28 rotor (of any description, including an HRC one) will not fit. Yes, you could in theory butcher an HRC crank to fit a stock flywheel to it.
