Periodic Maintenance Procedures
Drive Chain Slack Adjustment
Remove the cotter pin [A], and loosen the rear axle nut
Loosen the both chain adjuster locknuts [C].
If the chain is too loose, turn out the left and right chain
adjusters [D] evenly.
If the chain is too tight, turn in the left and right chain
adjusters evenly, and kick the wheel forward.
Turn both chain adjusters evenly until the drive chain has
the correct amount of slack. To keep the chain and wheel
properly aligned, the notch [E] on the left wheel alignment
indicator [F] should align with the same swingarm mark or
position [G] that the right indicator notch aligns with.
Misalignment of the wheel will result in abnormal
wear and may result in an unsafe riding condition.
Be sure the wheel is properly aligned.
Tighten the both chain adjuster locknuts securely.
Tighten the rear axle nut.
Torque - Rear Axle Nut: 130 N·m (13.3 kgf·m, 95.9 ft·lb)
Turn the wheel, measure the chain slack again at the tight-
est position, and readjust if necessary.
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 degrees.
Loosen once and tighten again when the slot goes past
the nearest hole.
Bend the cotter pin [A] along the nut [B].
A loose axle nut can lead to an accident resulting in
serious injury or death. Tighten the axle nut to the
proper torque and install a new cotter pin.
