CHECKING THE PARTS

Rod
The sliding surface must not be lined and/or scratched.
If the lines are deep, replace the rod.
Use a dial gauge to check that any curving in the rod is
less than the limit value.
If above the limit value, replace the rod.
Curve limit: 0.007 in (0.2 mm).
WARNING
NEVER straighten a curved rod; this will weaken
the structure of the vehicle, making it dangerous to
use.
Wheel support
Make sure there is no damage and/or cracking and
replace if necessary.
Spring
Make sure that the spring is in perfect working order.
Pumping element
Make sure it is in perfect working order and replace if
there are any signs of damage.

ADJUSTING THE REAR SUSPENSION

The rear suspension is comprised of a pair of dual-
effect shock absorbers (braking in compression/
extension), fixed to the engine by means of a silent
1
block.
The standard factory setting is for a rider weighing
approximately 154.3 lbs (70 kg). For different weights
and requirements, use the pin wrench (supplied) on
the ring nut (1) to define ideal use conditions (see
chart).
Calibrate both shock absorbers to the same
position.
