I am looking at an 2003 Air Warrior Elite with 120 hours? I am going for a test drive this week, but I had a few questions about the motor. How clean should the motor be? If the owner never specifically cleaned the motor, should it still be very clean? There is just a little oil residue on parts of the motor. I would never question this on a car, because it is a fact of life. Also, there are one or two small pieces in the engine compartment that are rusty. Should anything be rusty? I should mention that this is a v-drive with the 350 Mag.
