Drive Chain
Chain Tensioner
NOTE: The drive chain should be inspected
monthly. New chain has a tendency to
stretch.
Figure 14
Remove the chain case top cover. Check
tensioner spring (Item 1) and chain (Item 2)
[Figure 14] for proper tension. Replace the
tensioner spring if it becomes too loose to
maintain proper chain tension.
NOTE: Chain tension is preset with the tensioner
spring. If the chain becomes excessively
loose, it may be necessary to remove one
link (two pitches). If unable to reassemble,
add an offset link to lengthen the chain.
