first off mix your fuel between 32:1 and 40:1 no less than that. Next don't ride in terrain that is going to make the bike have to work ie: sand, mud,loose dirt, hills, this will cause your engine to rev high creating heat and heat is your worst enemy when breaking in a bike, so just take it easy ride on a hard surface and don't hold the throtle over half way to long for the first couple of rides. Also don't go out and ride all day with out stoping, take a break every little bit and let the bike cool off. Thats about it just keep the engine cool because if you don't you're going to be trying to get the melted piston out of your cylinder. After you run about two tanks of gas through the bike you can mix the gas at what ever ratio you you usualy do and ride hard.
