At first start up, keep the engine just above idle and give it a few revs up and down. This power on and power off RPM breaks in the piston and rings evenly on the intake and exhaust sides. If air cooled, once the engine builds up heat where it becomes too hot to touch, shut the engine off.

Is it bad to go over 3000 rpm?

Running an engine some 3000 RPM below its redline should be absolutely find for extended periods of time. It might “sound” a bit revvy if you run the engine at that RPM when stationary – and indeed it might get hot quite quickly as it will not have the cooling airflow that occurs when driving.
