Adjustment
Drive chain slack should be checked and adjusted,
if necessary, every 1,000 km. When operated at
sustained high speeds or under conditions of frequent
rapid acceleration, the chain may require more
frequent adjustments.
If the drive chain requires adjustment, follow the
procedures below:
1. Place the motorcycle on its side stand with the
transmission in neutral and the engine off.
2. Loosen the rear axle nut (1).
3. Loosen the lock nuts (2) on both adjusting nuts (3).
4. Turn right and left adjusting nuts an equal number of
turns until the correct drive chain slack is obtained.
Turn the adjusting nuts clockwise to tighten the
chain, or counterclockwise to provide more slack.
Drive chain slack should be 20 – 30 mm
(0.8 – 1.2 in) at a point midway between the drive
sprocket and the rear wheel sprocket. Rotate the
rear wheel and recheck the slack at other sections
of the chain.
5. Check that the rear axle alignment is correct. The
index mark (4) should be aligned with the rear edge
of adjusting slot (5).
6. If the rear axle is misaligned, turn the left or right
adjusting nut to align it correctly. After adjustment,
recheck chain slack.
