Remove the 6mm bolts holding the reduction cover
and inspect them for damage as above. They are
less likely to be over-tightened or stretched, but they
should still be checked. Remove the output shaft oil
seal from the reduction cover.
Check the chain for excessive wear. If the chain comes
within 0.125” of touching the clutch case, the chain and
the sprockets should be replaced as a set.
Remove the 8mm bolt holding the weight holder and
outer pressure plate to the clutch assembly. Be sure to
closely inspect the 8mm bolt and washer as mentioned
above. Replace as needed.
With the clutch assembly completely removed,
check the clutch center and sprocket basket. The
clutch center should slide into the basket easily and
spin freely, but it should not have any side-to-side
movement. If the clutch center moves side-to-side, it’s
a sign of worn brass bushings in the basket or a worn
clutch center. Both parts should be replaced.
