[5-F Dawg]

I only use Motul 300v full synthetic in all my toys. ZX10R, KX450F, KX250F, Pit bike... hell, I put it even in my pressure washer engine:lol:
Seriously, best oil money can buy IMO.

P.S.
-I have never taken a clutch out to soak it because of switching oil.
-I only soak brand new clutch plates in oil BEFORE installing them in the bike.
-I switched to the synthetic after the break in period.
-I change it every 3000kms

jeez how mcuh does that cost you?
