A muffler with a spark arrestor securely attached. If you lose it, you will be required to replace it at the next checkpoint. The static dba test will require a maximum limit of 96 dba at 20 inches. (RULE WILL BE ENFORCED) Mufflers may be repaired at any time check. Spark arrestors ARE required. Check the US Forrest Service Spark Arrestor Guide - Off Highway Vehicles to verify if your unit is qualified https://www.fs.usda.gov/t-d/pubs/pdfpubs/pdf21511814P/2151_1814P_SparkArresterGuide.pdf

An Idaho off-road sticker is required purchasing info at https://parksandrecreation.idaho.gov/registration-permits/

Helmet and Mototally Transponder required. Mototally transponders are available for purchase and synced for scoring during registration.

The machine will be impounded by the organizers. Each rider may claim their machine ten minutes before the scheduled time of departure. The rider cannot start their machine in the work area. The rider can work on their machine in the work area.

Riders are allowed to change parts in the work area and at each time check between the white and yellow flags. Tubes can be replaced at any time. Tires may be changed only at the final check of the day.

Within one minute of the starting signal having been given, the rider must have started the engine and crossed another line 20 meters from the start. A rider not crossing the 20-meter line within one minute will be penalized by 20 points. Riders arriving more than one minute late at the starting line will be penalized by 60 points per minute. The minute in which the rider arrives at the start line will be

considered as the new start time.

Putting gas and oil into your motorcycle is only allowed at each time check between the white and yellow flags. Gasoline only will be allowed just beyond the time check. You must bring the gas to the bike. You cannot ride back to flags.

A time check will be indicated by white flags 60 yards before the time-line. The yellow flag is the time-line. The clock will be located within a viewable distance beyond the time-line. A rider cannot cross this time-line with their machine until their time due appears on the time clock. If a rider does pass the yellow flag with their bike, they cannot go back and must proceed into the check for time recording. The rider may be disqualified if they are identified going in the reverse direction on the course or in the time check area.

Think of the interval between each checkpoint as a separate little “test.” Arriving late (or early) at any one of the course checkpoints does not require you to adjust your “interval time” for subsequent checks. If you arrive early or late from your due time at a check you will need to adjust the time you are due at subsequent checks, but NOT the interval.

It is the responsibility of the rider to know when they were due at any check point. The organizer will provide the time schedule prior to the start of each day. The time schedule between each time check is a separate test. If you are late at any time check you DO NOT have to make this time up. Doing so will only make you early at the next time check. The time at which you go through any check sets the start time for the next interval to the next check.

Example: Check # Original Time Due: Time In: Points:

1 9:42  9:42 0

2 10:25 10:27 120

3 11:09 11:11  0

You were on time at check #1, but two minutes late at check #2. By being late you now have a new “start time” for the next interval. You will need to adjust your original time due at subsequent checks by two minutes to stay on time. If you had gone into check #3 at your original due time you would have been penalized 120 points for being two minutes early. Always maintain the interval. 

Hour out rule: You can never be more than one hour past your ORIGINAL time due at any check or you will be disqualified. 

Hint: If you are really running late (like more than 30 minutes) then roll through the checks as soon as you arrive to make up time if possible. If you are that late you are already on bronze level, so early points really don’t matter that much, but going over your hour will.

These tests are the most critical measurement in an event. The basic outline for a special test is that it should be “not too difficult and not dangerous …. forbidden to practice, and specially prepared for the purpose.” It should be ridden as fast as you can successfully negotiate the course.

You can walk the grass track prior to the start of the event, but you may not ride (not even a bicycle) on any portion of the course—including the special tests—prior to the start. 

If your machine is running correctly, do the basics keeping an eye on the time and go through the check when your time is up.

If you are now on a bronze level, which means more than approximately 20 minutes late on your score, you can use the one-hour late rule and work on your bike. BUT, push in no later than 59 minutes past your original scheduled time, not 59 minutes from your arrival at this final check. 

You are disqualified if you are 60 minutes late from your original scheduled time at any check.

• Gold Medals will be awarded to riders whose total number of points does not exceed 10% of the number of points achieved by the first (winning) rider of that class.
• Silver Medals will be awarded to riders whose total number of points does not exceed 40% of the number of points received by the first (winning) rider of that class.
• Bronze Medals will be awarded to all other riders who finish within their hour late allowance.

Early/Late arrival at a time check = 60 points per minute

Special Tests = One point for every second in the test

Starting later than the originally scheduled time = 60 points per minute late

Stopping between the yellow flag and check crew at time check = 60 points
