Centring the rim
Put a quadrant gauge next to the rim and rotate the wheel to measure
the axial centring.
Put the dial on the inside of the rim circumference, rotate the wheel
and the difference between the largest and smallest measurement
is the centring measurement.
If the wheel is slightly off-centre then this can be corrected by
loosening certain spokes and tightening others in order to change
the rim position. If the rim is bent or crooked then it must be replaced.
NOTE
A soldered area on the rim may give an excessive reading.
Ignore this while measuring the centring.

WARNING
Improper removal of the spring from the rear shock absorber body
may cause the spring and associated parts to be ejected at high
velocity. Always wear eye and face protection. Removal and installation
of spring should be performed by an official distributor.
WHEELS
Tyre
. Tyre pressure affects traction, handling, and tyre life.
. Adjust the tire pressure to suit track conditions and rider preference,
but do not deviate excessively from the recommended pressure.
NOTE
Tyre pressure should be tested when the tyre is cold before
driving.
Track conditions
- When the track is wet, muddy, sandy or slippery, reduce the tyre
pressure.
- When the track is stony or hard, increase the tyre pressure.
Spokes and rims
The spokes on both wheels must all be tightened securely and
evenly and not be allowed to loosen, Unevenly tightened or loose
spokes will cause the rim to warp, hasten nipple and overall spoke
fatigue, and may result in spoke breakage.
