Yes, run it hard but vary rpms and engine load in short bursts with cooldowns. This is a proven break in method that will get you a powerful engine that will last a long time. Babying a 2 stroke won't get you anywhere but glazed rings, poorly mated surfaced, never achieving full compression etc...
Tell me this, how do you folks break in your 2 stroke chains saws or your 4 stroke lawnmower? Do you let it idle for several tanks? No, you go out and use it and by the nature of their use, the engine load is varied and break in takes care of itself.
