i have had engines that have seen 8000rpm both ways but it is always nice if the weight can stay on the crank counter weight .some engines it just can not happen less many plugs of heavy metal are put in the crank counter weight that were a fully counter weight crank like a 8 plate help load the crank right thru the RPM range boils down to the use and RPM of the engine and whats not a fast rule just had one that customer took to 10000
