4-10 MACHINE TUNING
FRONT FORK TUNING PROCEDURE
Test ride the motorcycle and find out how the front suspension reacts on various types of surface. According
to the symptom noticed, adjust the front fork to the best setting for rider and race track conditions. To adjust,
attempt changing fork oil capacity and compression and rebound damping force following the instructions
below.
NOTE:
When adjusting the front fork oil capacity, make sure that the oil capacity is within the specified range. Also,
the capacity should be increased or decreased by 1 ml (0.034/0.035 US/Imp oz).
When adjusting the damping
force
, attempt turning the adjuster 1 to 2 click stops at a time for each adjust-
ment.
