Inspecting the swingarm chain buffer
Measure the buffer thickness (a) at many points of
the upper and lower sides of the buffer. Wear may be
distributed unevenly across the buffer, so examine it
closely. Pay special attention to the area nearest the
pivot shaft. Replace if it is out of specification or
shows deep grooves or uneven wear.
1. To replace the buffer, place the vehicle on a work
stand so there is no danger of it falling over while
you work.
2. Remove the buffer mounting bolts.
3. Remove the and the old buffer. Make sure you
clean the buffer mounting screws with contact
cleaner and apply Loctite #242 agent before
installing the new buffer.
4. Install the new buffer and tighten screws to 7.0
lbf•in (2.0 N•m).
Inspecting the drive chain guide block
1. Measure the guide block thickness (a). Replace
with a new block if wear exceed service limits.
2. Inspect the drive chain guide and guide block for
cracks, wear, and/or any other damage. Replace
if any damage is found.
3. Check the drive chain guide bolts and tighten to
9.0 lbf•ft (12.2 N•m)
Inspecting the drive chain rollers
1. Rotate the upper and lower drive chain rollers.
The rollers should rotate smoothly.
2. Measure the outside diameter of the upper and
