Max speed won't hurt a thing provided the bearings can take it. With a bushing engine, I never had a problem going full throttle down a steep hill and running full throttle ALL day long.
You gotta give these HT engines a break, they aren't that bad. There is no reason why you couldn't run it at speeds as high as 8,000 rpm. The newer engines are much smoother and better balances than the older ones. I've got 2 stroke engines that are in the 25-50 cc range that I prop (they are on model airplanes) to spin 8500-9000 rpm at max throttle.
