Throttle control is crucial in all aspects; you can get yourself out of sticky situations by hitting the throttle.

If you can't see, you can't ride. What I like to do is totally focus on breathing down. You're basically putting your top lip over your bottom lip and blowing all of your air down away from your goggles. Another thing is never put your goggles under the hood unless absolutely necessary. Whenever I stop and need to take my goggles off I will place them with the lenses up over the handlebar grip.

Set up your sled for your riding style. I usually have some good shocks on the front and rear of my sled as well as running board supports to stop the tunnel from bending. I put screen over all my hood vents to stop the pow from filling up my engine compartment. I find that without the screens, the sled likes to bog out bad in the pow and the snow also hits the engine and melts and then re-freezes around your steering and causes problems. I also put some venting around my clutches (usually higher up on the side panels). You can buy cheap screen door material from most hardware stores and it works great.
