1. All participants must be at least 14 years of age.
2. All participants must be physically able to race a motorcycle. Any rider
who has a disability must prove they are competent on a road course to be
allowed to enter a race. Any racer with a medical condition that could
cause danger to themselves or others such as epilepsy should not race.
3. All participants must be free of illegal narcotics and alcohol. If we
suspect it is a problem, drug or alcohol testing may be required. 

1. You may obtain an ASMA Roadracing license by filling out a license
application either at an event or you may download a form online. In
addition, ASMA will send all current license holders a renewal form at the
end of each year.
2. All licenses are good for the current racing season. All licenses expire on
December 31st of the year they are purchased.
3. To obtain an ASMA license, you must pass a race clinic. ASMA holds a
race clinic on Saturday morning at each ASMA roadrace. In addition, we
have many license clinics during the off season. At the completion of the
clinic you can purchase an ASMA race license, receive a number and enter
races.
4. If you are already licensed, we need to see your current race license or
a photocopy of your license.
5. One event licenses. One event licenses are available at a cost of $15 per
event. A one day license entitles you to points and contingency. 

1.  . In addition to fines and other penalties, ASMA Officials have the right
to revoke your license, either temporary or permanently for any offense
deemed unacceptable.
2. Rough riding. This is defined as intentional contact with another racer.
We understand that accidents happen, we also want to make sure our
racers are safe. Questionable riding can result in anything from a warning
to loss of your license and forfeit of your entry fee, penalty is up to the
head race official.
3. If you have a problem that’s not getting resolved, don’t yell at our staff;
take your problem to the head official. Failure to do so may result in
penalties.
4. Speeding in the pits. Pit speed is 5mph. Speeding will result in fines.
Fines are $20 first offense, $50 second offense, $100 third offense. All
speeding fines will be put into a purse for one of our races. Blatant
speeding, ASMA reserves the right to penalize either higher fines or
suspension of racing, or both.
5. Cutting the course. Any rider that goes off track and cuts the course and
re-enters the track with an advantage will receive a stop and go penalty.
Stop and go penalties will take place in the hot pits. When serving a stop
and go penalty, you must come to a complete stop where directed by the
race official.
6. Jumping the start. Jumping the start will result in a stop and go penalty.
7. Either you or a representative must attend the riders meeting each
morning. Failure to attend the riders meeting will result in possible
suspension from riding that day.
8. Racers are subject to represent both themselves and ASMA in a fair
manner, both on and off the racetrack. Failure to do so may result in fines,
suspensions or both. The ASMA head official has the final say in these
matters. 

1. . A fine or penalty may be appealed by using an appeal form available
from race officials. Appeals will be brought to an appeal board made up of
both racers and officials and put to a vote.
2. Protests may be made to determine eligibility on competitor’s
motorcycles. To file a protest, fill out an official protest form available
from ASMA officials. Cost for a protest is $15 for visible infractions
(anything that can be seen without removing parts from a motorcycle),
$25 for all other non internal engine protests and $700 for internal engine
protests. If the motorcycle in question is determined legal, all protest
money is turned over to the owner of that motorcycle for re-assembly. If it
is determined illegal, protest money will be returned to the person who
filed the protest. If motorcycle is deemed illegal, its owner will lose all
points for that event in which the bike is illegal.  

1. . Generally speaking, rules are made either by committee, voting, or by
ASMA staff. If a rule is made by ASMA staff, it is most likely made by
Roger Heemsbergen, who has raced for 33 years. If it is made by voting, it
is most likely done at either a riders meeting, or done by a poll through the
message boards at ASMAracing.com. If it is done by committee, we
usually pick 5 racers who have ridden with us for at least a year to help
make decisions. It’s not always the same 5 racers, we want everyone to
get involved with how the series is run, so don’t be surprised if we ask
YOU to help us make rules or decisions  

1.   Championship points are awarded to participants in each event. In
addition to class championship points, riders are also awarded overall
points for each class raced, with the exception of the Beginner race which
doesn’t award any points.
2. In combined classes which don’t use amateur and expert status, such as
Lightweight GP, Lightweight Superbike, Formula 40, Heavyweight Twins,
Kawasaki 650 Spec, Modern Vintage and Team Sprints, a riders finishing
position will be awarded to amateur or expert overall points, depending on
their status.

standings in Formula Arroyo (ULGP). This means racers with a low

Amateurs and Experts.
