In addition to checking the slack, rotate the rear wheel to inspect
the drive chain and sprockets for damaged rollers, loose pin and
links, unevenly or excessively worn teet, and damaged teeth.
Slack Adjustment
- Loosen the rear axle nut and both chain adjuster locknuts.
- Turn the nuts on the chain adjusting bolts evenly until the drive
chain has 30-50 mm. of space between the chain and the swing
arm. To keep the chain and wheel aligned, the notch on the left chain
adjuster should align with the same swing arm mark that the on the
right chain adjuster aligns with.
(B) (C)
Wheel alignment can also be checked using the straightedge
or string metod.
Misalignment of the wheel will result in abnormal wear and may
result in an unsafe riding condition.
- Tighten the axle nut to 98 N-m. (70ft-lbs).
- Tighten both chain adjuster locknuts.
- Rotate the wheel, measure the chain slack again at the tightest
position, and readjust if necessary.
If the axle nut is not securely tightened an unsafe riding
condition may result.
Drive Chain, Chain Guide, Chain Slidder, and Sprockets Wear
Inspection.
(A)
When the chain has worn so much that it is more than 2% longer
than when new, it is no longer safe for use and should be replaced.
Whenever the chain is replaced, inspect both the engine and rear
sprockets, and replace them if necessary. Worn sprockets will cause
a new chain to wear quickly.
