Going to change the oil its been sat in the garage for a year after buying it!

Repsol 10W40 4T Moto Synthetic

nothing wrong with oil sat about......

any 10/40W motorcycle oil will do. just not fully synthetic

With leopard on this one, Oil doesn't go off or anything.

I just whack halfords own 10W40 semi synthetic in mine. I don't bother putting expensive stuff in because it burns it anyway.

im going to go 4 this 1 i think Repsol 10W40 4T Moto Synthetic, but its fully synthetic someone said dont put fully in?

what about this stuff Castrol Magnatec says its for cars but looks top bollocks?

Why do you ask for advice then not listen to it.

Fully synth will make your clutch slip.


Car oil also has an anti friction substance in it, Which will also make your clutch slip.
Reason it doesn't affect cars is because they have dry clutches, Or they have their own Gearbox Oil.

Stick with Motorcycle 10w40, Anything will do providing its Semi Synth.

"Fully synth will make your clutch slip."
+1 on that.. and is why *I* said dont use it

Not true.. there is nothing in manual about oil type. Just
Oil type: API grade SE, SF or SG
Oil viscosity: SAE 10W40

I used this season Repsol 10W40 4T Moto Synthetic and no any trouble with clutch. On CB400SF we used MOTUL 300 V 4T Factoru Line 10W40, no any issue with clutch as well
