Just picked up a pretty nice 2004 450R on a trade and have a few questions since there was no owners manual. How much/what weight oil for both the engine and tranny? Not planning on keeping it even though it's crazy fun but want to be sure the fluids are fresh for whoever ends up buying it for my peace of mind. Wouldn't mind keeping it for playing but the girlfriend wants a 4wd of her own and doesn't like driving my Polaris because of the big lift/tires.
