Is it bad to rev in neutral?

Yes, this causes engine wear. When the transmission is in neutral and the engine is “revved” without any load, the spinning engine internals will accelerate, gathering rotational and lateral forces at a faster rate than designed by the manufacturer. Rapidly revving an engine will heat up the piston rings much faster.
