2-28 PERIODIC MAINTENANCE
Insert a new cotter pin [A].
When inserting the cotter pin, if the slots in the nut do
not align with the cotter pin hole in the axle, tighten the
nut clockwise [B] up to next alignment.
It should be within 30 degree.
Loosen once and tighten again when the slot goes past
the nearest hole.
Bend the cotter pin [A] over the nut [B].
Wheel Alignment Inspection
Check that the notch [A] on the left alignment indicator [B]
aligns with the same swingarm mark or position [C] that
the right alignment indicator notch aligns with.
If they do not, adjust the chain slack and align the wheel
alignment (see Drive Chain Slack Adjustment).
Wheel alignment can be also checked using the
straightedge or string method.
Misalignment of the wheel will result in abnormal
wear, and may result in an unsafe riding condition.
Drive Chain Wear Inspection
Rotate the rear wheel to inspect the drive chain for dam-
aged rollers, and loose pins and links.
If there is any irregularity, replace the drive chain.
Lubricate the drive chain if it appears dry.
Stretch the chain taut by hanging a 98 N (10 kg, 20 lb)
weight [A] on the chain.
Measure the length of 20 links [B] on the straight part [C] of
the chain from the pin center of the 1st pin to the pin center
of the 21st pin. Since the chain may wear unevenly, take
measurements at several places.
If any measurements exceed the service limit, replace the
chain. Also, replace the front and rear sprockets when the
drive chain is replaced.
