Periodic Maintenance Procedures
When inserting the cotter pin, if the slots in the nut do
not align with the cotter pin hole in the axle shaft, tighten
the nut clockwise [A] up to next alignment.
It should be within 30 degree.
Loosen once and tighten again when the slot goes past
the nearest hole.
If the axle nut is not securely tightened, or the cotter
pin is not installed, an unsafe riding condition may
Check the rear brake.
In wet and muddy conditions, mud sticks to the chain
and sprockets resulting in an overly tight chain, and the
chain may break. To prevent this, adjust the chain to 58
68 mm (2.28
2.68 in.) of slack whenever necessary.

Drive Chain Wear Inspection

Rotate the rear wheel to inspect the drive chain for dam-
aged rollers, and loose pins and links.
If there is any irregularity, replace the drive chain.
Lubricate the drive chain if it appears dry.
[A] Bushing
[B] Roller
[C] Pin
[D] Pin Link
[E] Roller Link
Stretch the chain taut by hanging a 98 N (10 kgf, 20 lb)
weight [A] on the chain.
Measure the length of 20 links [B] on the straight part [C] of
the chain from the pin center of the 1st pin to the pin center
of the 21st pin. Since the chain may wear unevenly, take
measurements at several places.
Chain 20-link Length
317.5 ∼ 318.2 mm (12.50 ∼ 12.53 in.)
Service Limit: 323 mm (12.7 in.)
If any measurements exceed the service limit, replace the
chain. Also, replace the front and rear sprockets when the
drive chain is replaced.
