You'll find that any fuel can be run in any engine, so long as the fuel receives the correct conditions for it to burn.
In the real world, higher octane fuel in a standard engine will not make more power, though it will maintain more even combustion chamber pressure throughout the power stroke; giving slightly higher low and mid-range torque.
Typically the engine will also operate more smoothly.
My preferred fuel option is 98 octane but since i use 20:1 the octane number is reduced due to the higher oil/fuel ratio as compared to 35:1 or 50:1
If you wanted to run Nitromethane, my advise would be to run a twin carburettor setup, with one carburettor run with conventional fuel/oil premix and the second carburettor run with delayed throttle opening in a linked setup; running a seperate nitro/alcohol mixture and jetted accordingly, together with oil injection so the overall air/fuel ratio and fuel/oil ratio is correct at wide open throttle.
Some of the Dellorto carburettors have an oil injection port that would support this goal.

geeeez..why bother?
you're never going to get much more power out of a chinese 2 stroke, even if you add every speed part and do every porting, polishing, milling and tuning trick out there.
these motors were just not meant to make that kind of power.
