What do people reckon on best approach to running in an engine with newly honed bores and new rings? I'm thinking of an air cooled 360 degree parallel twin such as Norton, Triumph or BSA here, and built using factory clearances (or slightly over, eg: 5 thou skirt clearance).
Modern thinking seems to be to give the engine plenty of work right from first startup, but I was brought up thinking it was best to be gentle for the first few hundred miles and gradually increase the workload.
Who does what on here?
