TUNING THE EXP
This kit includes multiple spring settings to adjust the
engagement RPM of the EXP friction disk. The EXP friction
disk comes preinstalled with the recommended “Medium”
setting. See the included Setup Sheet for a chart of the
available EXP spring configurations.
You may have to adjust the engine idle speed to prevent
free-wheeling and maximize engine braking. There should
be a slight amount of drag when the bike is warmed up and
idling in gear. The idle should not be so high that the bike
moves forward while in gear with the throttle closed.
However, with a small opening of the throttle, the bike should
move forward.
Changing the EXP Springs
1. Using a flathead screwdriver, push the ¼ turn pin in far
enough to clear the opposite side of the EXP to unlock
the pin.
2. With the pin still pushed past the base, turn 90° to
remove the pin and spring.
3. Remove the remaining 2 pins and springs from the same
side of the EXP base.
4. Drop a new spring into the spring slot on the base, then
add the ¼ turn pin.
5. Push the ¼ turn pin in far enough to clear the base, then
turn 90° and release the pin. The pin should sit almost
flush with the EXP base.
6. If necessary, repeat this process on the other side of the
EXP to complete the spring configuration.
