If you don't have a extended motorcycle the stock wheelbase class is a good place to start.
There should be a tech inspection before the race. They should check the items listed under Motorcycle above and ask you what class you are racing in. They may give you a ticket for signup.
You will need your AMA card and District 14 card (you can get these the day of the race), know what class you are racing in, answer a few questions, sign a release and pay.
Bring your motorcycle to the pit area.
There will be a riders meeting before the race, usually at the bottom of the hill. They will talk about important information on how the race will be run and safety information.
Wait for your class
When your class is called, take your motorcycle to the bottom of the hill and get ready to be lined up.
When it's your turn move your motorcycle to the starting area and prep the line you will be taking. Make sure your gas is on and your tether is attached to you. The starter will let you know when the hill is ready for your run. The race doesn't start until the light at the bottom of the hill is broken.
Make your run and return your motorcycle to the pit area. You will get one more run.
