Adjusting the Drive Chain Slack
Adjusting the chain requires special tools.
Have the drive chain slack adjusted by your dealer.
1. Shift the transmission to Neutral. Stop the engine.
2. Place your motorcycle on its side stand on a firm,
level surface.
3. Loosen the rear axle nut.
4. Loosen the lock nuts on both sides of the swingarm.

5. Turn both adjusting nuts an equal number of turns
until the correct drive chain slack is obtained. Turn
the adjusting nuts clockwise to tighten the chain.
Turn the adjusting nuts counterclockwise to provide
more slack. Adjust the slack at a point midway
between the drive sprocket and the driven sprocket.
Check the drive chain slack (page 46).
6. Check rear axle alignment by making sure the
chain adjuster index marks align with the rear
edge of the adjusting slots. Both marks should
correspond. If the axle is misaligned, turn the right
or left adjusting nuts until the marks are aligned
and recheck chain slack.
