NOTE
Wheel alignment can also be checked using the straightedge
or string metod.
WARNING
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.
WARNING
If the axle nut is not securely tightened an unsafe riding condition
may result.
Drive chain, chain guide, chain slidder, and sprockets wear
inspection.
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.
NOTE
For maximum strech resistance and safety, a genuine part must
be used for replacement.
To minimize any chance of the master link coming apart, the
master link clip must be installed with the closed end of the
«U» points in the direction of chain rotation.
Chain Guide Wear
Visually inspect the drive chain guide. If the guide is worn excessively
or damaged, replace it.
