Re: Oil
HI
Firstly just need to confirm engine oil goes in the tank and is fed by pump to the cylinders. Transmission oil goes in the gearbox.
Using semi synthetic oil for the engine is fine but just make sure if you were using mineral oil before that you drain the tank as they don't mix well and it causes 'glooping' which is similar to clotting.
Using anything other than mineral oil in your gearbox is not recommended as anything synthetic can cause the clutch plates to stick together and slip.

Re: Oil
I've been trying to understand the JASO MA standard for a while. The oil I use (Motul Transoil Mineral), does not have that on it, although it specifically says it is for wet clutches. Presumably not all oils are tested to this standard. I've also seen reference to GL4 which is the API rating and that relates to the gearbox standard I think. Of course many folks use a classic 20/50 which I don't suppose meets any of these standards. I've used 20/50 myself but I get less clutch drag from cold with the Motul Transoil so have stuck with that.
