- If the straight portion of a course is longer, the secondary reduction
ratio should be reduced so that the machine speed can be increased.
- When the course has many corners or uphills or is wet, the
secondary reduction rario should be increased so that gear shifting
is possible with smooth acceleration.
- Actually, the speed must be changed depending on the ground
condition on the day of race and therefore, be sure to run through
the racing circuit prior to a race and set the machine suitable for the
entire course.
- If the straight portion of a course on which the machine can be run
at maximum speed is longer, the machine should be set so that the
maximum machine speed can be developed toward the end of the
straight course, but care should be taken not to over-rev the engine.
- It is difficult to set the machine to be best suited for all portions of
the circuit. Therefore, determine which circuit portions will have the
greatest effect on lap time. Set the machine for these portions.
Confirm your settings by recording lap times after each change. In
this way the machine will deliver best performance for the entire
circuit.
Special Care According to Track Conditions.
1. In dry, dusty conditions (such as volcanic ash or fine powdery
dust) special care must be given to keep the air cleaner element
clean.
2. When riding on wet heavy clay the mud adheres to the tires and
other parts of the vehicle. The mud can add significantly to the weight
of the vehicle and therefore reduce performance. Take care to
remove built-up mud from the tires and chassis after each ride,
before drying occurs.
3. The engine works hardest in muddy conditions and the radiator
can become clogged with mud. Take care not to overheat the engine
in these conditions. The engine also works very hard when ridden
in deep sand.
4. In muddy or sandy conditions adjust the chain looser than in other
conditions as the chain and sprockets will pack with mud/sand and
reduce chain slack.
5. Check chain and sprocket wear frequently when riding in mud or
sand since wear is increased in these conditions.
6. In dusty conditions as the air cleaner collects dust, the engine
runs richer. Therefore it may be advisable to run slightly leaner jetting
(main jet) in very dusty conditions.
