bobby - to enter the race, you would need a CA red or green sticker on your bike (or an out of state sticker), you need to also get a district 37 compettiion card and sign up for AMA membership - between those and the race entry fee, start up will run you about $100. You also need a forest service approvede spark arrestor on your bike. You can sign up foir the AMA card and District 37 card at the race. Look us up ... we'll be at the Aliklik campground tomorrow - I have a red Toyota Tacoma pickup, Gas Gas bike, and my buds have 2 KTMs and a Yamaha 250 ... my buddy will also have his trailer and a silver or black pickup - look around the campground - you'll find us.
