Doubt that there would be much benefit to warming the crankcase there is a minimum amount of oil in it, the Warrior has a dry sump oiling system the oil tank is behind the right-side cover / under the seat.

The coldest temps I rode mine in was 17 degrees. The bike started just fine. My fingers however, did not deal with the cold near as well as the motor did.

From a guy that rode in Chicago winters when the streets were dry: Suggest nitrile gloves under your gauntlet gloves.
