matches the maximum horsepower
RPM.

There are 6 positions numbered 1 to 6.
Each position modifies maximum en-
gine RPM by approximately 200 RPM.
Lower position numbers decrease en-
gine RPM in steps of 200 RPM and
higher position numbers increase it in
steps of 200 RPM.
Example:
Calibration screw is set at position
4 and is changed to position 6. So
maximum engine RPM is increased
by 400 RPM.
Procedure
Just loosen lock nut enough to pull
calibration screw partially out and
adjust to desired position. Do not
completely remove the lock nut.
Torque lock nuts to 10 N•m ± 2 N•m
(89 lbf•
in ± 18 lbf• in ).
NOTICE
Do not completely re-
move calibration screw otherwise
internal washers will fall off. Al-
ways adjust all 3 calibration screws
and make sure they are all set to the
same position.

WARNING
NEVER disassemble or modify the
drive pulley.
Improper assembly or modifica-
tions could cause the pulley to ex-
plode violently under the stress
generated by the high rotational
speed.
See your Lynx dealer to maintain
or service the drive pulley. Im-
proper servicing or maintenance
may affect performance and re-
duce belt life.
Always respect
maintenance schedules.
