What are the extras on the camshafts?
Just checking the valves and noticed all the extra bits flapping around on the camshafts. Both exhausts have this centrifugal arm disc thing (though in different places) and I'm very curious what it is.
The intake cams have a post in the end (maybe a sort of counter balance? Oil flinger?)
The parts diagrams don't call them out individually, but their clearances are loose enough that I suspect they could be contributing a fair bit to the clatter while running. Does anyone know what they are?
