Oil Cooler [?!?]

10w-40 is the factory recommend oil and 10w-40, of all the common oils, is a weight that is designed to handle the broadest range of heat variance in the world.

We do not recommend anything higher than a 15w-40. The flow rate and tolerances inside the GZ engine need something that will actually mate and lubricate. Cooling is accomplished through the fins, obviously, and the metal combinations found in the head.

If heat exchange is a real concern of yours, simply increase your main jet one size, enriching your mixture and running cooler - Do not leave your bike idling for any extended period of time - and just ride.
