MegaMang, your question about plastic on the belt begs the question of whether or not you could sheath the wiring harness as well.
Love the Pam idea, and no John, I didn't misunderstand about the Mud Off, I understood it was a preventative measure before racing. I was just referring to the fact I figured it would take a pressure washer after every race to clean her up. The suggestions for the Mud Off, baby oil, Pam, etc. sets my mind at ease about a lot of this. One of my biggest concerns was the damage the dirt and mud could do to the engine, brakes, belts, wiring harness, the whole nine yards. I was afraid that over heating on the track due to the dirt might be a major concern.
All of the suggestions and discussion is very valuable to me, please keep it coming. Even if I'm not jumping into the discussion a lot, rest assured I'm taking notes and learning. And I'll jump in everytime I don't fully understand or have another question. This is going to be an adventure, I have a feeling!
