Several observations from the day, in no particular order:
1. Be very careful if you're gonna air down for off road. I had my front tire come off the bead. Another rider had a Slime brand portable compressor, and I was able to reseat and reinflate the tire.
2. Heindenau K60's are almost useless in mud. The center strip that gives long wear prevents the tire from digging in to the muck.
3. Get a good skid plate and side bars. My AltRider armor paid for itself several times over. Some of the rock hits were pretty loud!
4. I removed my windshield for the event. One less expensive part to worry about.
5. Traction Control is your friend. It allowed me to hammer the throttle in TC2. The drag race in a wet, muddy field and the 1/2 mile hill climb were crazy good fun.
6. I found the anti lock brakes to be a liability, especially on slippery downhill singletrack. The tires were also part of the problem.
7. Don't try to ride your S10 like a real dirt bike. It weighs almost twice as much as my KTM.
8. Get your weight back and shift your body. These bikes are very nose heavy and plow in tight turns. Getting your body weight to the outside helps prevent the bike from "falling in" to the turn.
9. My bike was a bear to clean, especially between the engine and skid plate. Also pay close attention to under the front fender and the center of the front rim. I was lucky the Motel manager put a hose out for me.
10. If you can, hone your skills on a real dirt bike first.
11. Always keep two fingers on the clutch when going slow in technical terrain, and don't be afraid to slip the clutch to keep from stalling.
12. Momentum is your friend. Don't stop to obsess over an obstacle.
13. Don't ride off road alone. Having help to pick up your bike is a bonus.
14. Remember; free advice is sometimes worth exactly what you paid for it. YMMV
