Check rear belt deflection: 

●

Inspect before every ride.

●

Adjust at the 500 mile (800 km) service interval.

●

Adjust at every 5000 mile (8000 km) service interval
thereafter.

The secondary drive belt should be checked for unusual
wear, cracking or loss of teeth. Check the belt sprocket for
unusual wear, broken teeth or damaged flange. When check-
ing deflection, have:

●

No rider or cargo weight on motorcycle.

●

Transmission in neutral.

●

Belt and sprockets at room temperature. 

●

Motorcycle upright (not on side stand).

1.

See 

 At the lower strand, position “A”, mid-

way between transmission sprocket and rear wheel
sprocket, apply 10 Ibs (4.5 kg) of upward force on lower
span of rear belt using 

2.

Measure belt deflection “B” several times, each time with
belt moved (by rotating rear wheel) to a different position
on sprockets. With sprockets rotated to tightest belt posi-
tion, belt deflection “B” (measured at position “A”) should
be 7/8-1 in. (22.2-25.4 mm).

1.

Adjust shock absorber spring preload. See 

.

2.

See 

 Loosen rear axle nut (metric), if not

already performed.

NOTE

After you loosen the axle nut, turn the axle and nut so the rear-
most flat on each side is parallel with the ends of the swingarm.

Check to be sure rear wheel axle is parallel with swingarm
pivot shaft.

3.

See 

 Measure each side from the flat to the

end of the swingarm, to be sure rear axle is correctly
located.

4.

Turn axle adjuster nuts (metric) on each side of swing-
arm to adjust belt deflection.

a. 

Turn clockwise to decrease deflection (increase ten-
sion). 

b.  Turn counterclockwise to increase belt deflection

(decrease tension). 

Turn each adjuster nut exactly the same number of turns
to maintain rear wheel alignment

5.

Tighten axle nut (metric) to 66-73 ft-lbs (89.5-98.9 Nm).

Keep dirt, grease, oil, and debris off the belt and sprockets.
Clean the belt with a rag which is slightly damp with light
cleaning agent.
