Rotational limiter immediately after cold start

Hi, have a short question If you start the engine immediately after (machine, Ö,l cooling water cold) in the limiter, what are the late follow? Know only from the moped fine bars in the cylinder but no more. Couldn’t be quite bad or? How does it look with a c14nz motor? Oil he has mixed 10W40 and 15w40 many greetings
