In rider surveys on Motorcycle racing forums, the vast majority use Rotella synthetic diesel oil. It meets manufacturers specs for pretty much any motorcycle with a wet clutch. Quite a bit cheaper than Amsoil. I've been using O,Reilly's Tractor Fluid for years in my CR500s. It's what most of the guys on the CR500 forum use. Way cheaper than Amsoil or other motorcycle oils. The big thing as stated previously is not to use automotive oils with friction modifiers. They will quickly glaze your plates.
