I wonder if the nickle plating on some of the engines has any problems still. If some plating peels off of something, it might foul the bearings causing premature failing. I sorta like the idea of plating all the ferrous metal parts, but you don't want it coming off later though. I would think that they would mask the gear teeth and the cam lobes so they are not plated. I assume that since OS sells jjillions of engines, so the odds are pretty good that they will have some failures. Unfortunately we don't know what the statistics are for it. usually on the forums we hear about all the horror stories but very few good stories.

OS Surpass II camshaft, nickel plated. Does OS still nickel plate the new engines? Does OS nickel plate the crankshafts on the 2 stroke engines? Do they still do this on the new engines?
