MAINTENANCE
ADJUSTMENT
Loosen the axle bearing holder pinch bolts.
Turn the bearing holder until the correct drive chain
slack is obtained, using the hex wrench in the tool
kit.
Tighten the axle bearing holder pinch bolts.
TORQUE: 21 N-m (2.1 kgfm, 15 Ibfft)
Recheck the drive chain slack and free wheel rota-
tion.
If the chain slack is excessive when the bearing
holder is turned fully rearward (the correct slack
cannot be obtained), replace the drive chain with a
new one.
To replace the drive chain, remove the drive
sprocket cover (page 10-7) and swingarm (page 18-
20).
CLEANING, LUBRICATION AND
INSPECTION
Clean the chain with a soft brush using a non-flam-
mable or high flash point solvent and wipe it dry.
Be sure the chain has dried completely before lubri-
cating.
Lubricate the drive chain with #80 - #90 gear oil or
equivalent chain lubricant designed for specifically
for use on O-ring chains.
Some commercially available chain lubricants may
contain solvents which could damage the O-rings
Wipe off the excess oil.
Inspect the drive chain for possible damage or wear.
Replace any chain that has damaged rollers, loose
fitting links, or otherwise appears unserviceable.
Inspect the drive and driven sprocket teeth for wear
or damage, and replace if necessary.
Never use a new drive chain on worn sprockets.
Both chain and sprockets must be in good condi-
tion, or the new replacement chain will wear rapidly
Check the attaching bolts and nut on the drive and
driven sprockets.
If any are loose, tighten them to the specified
torque.
