There is only 1 oil in the engine. This is not a CRF motor. Drain off the case, then fill to the required amount of fluid. It is just under 1 liter.

On my YZFs since the tranny and motor share the same oil, i changed them ever day I rode it at the track.

Well you will get a ton of opinions. But the Amsoil 10-40 motorcycle oil. It does not break down and IS GL rated for the transmission gears. Dont know of any other motor oil that is designed for use in a transmission with the GL rating.

I second the Amsoil...also ran Maxima, Redline and Honda HP in my CRF250 but have had best results with Amsoil. Whatever brand oil you decide to use I definitely recommend an Ester based synthetic from a reputable manufacturer.
