Swingarm Bearing, Sleeve Inspection
NOTICE
Do not remove the bearings for inspection. Removal
may damage them.
Inspect the needle bearings [A] and ball bearing installed
in the swingarm.
The rollers and ball in a bearing normally wear very little,
and wear is difficult to measure. Instead of measuring,

Coupling Bearing Inspection
Since the coupling bearing is made to extremely close
tolerances, the clearance can not normally be measured.
NOTE
It is not necessary to remove the coupling bearing for
inspection. If the bearing is removed, it will need to be
replaced with a new one.
Turn the bearing in the coupling b ...

partly open; which lowers performance,
burns the valves and
valve seats, and may cause serious
engine damage.
