CHAIN GUIDE
The drive chain must be checked, adjusted, and lubricated in
accordance with the Periodic Maintenance table in order to prevent
excessive wear. If the chain is worn or badly adjusted (to tight or
loose) then it may jump off the sprockets or break.
WARNING
A chain that breaks or jumps off the sprockets could snag on the
engine sprocket or lock the rear wheel, severely damaging the
motorcycle and causing it to go out of control.
Checking tension
The space between the chain and the swing arm at the rear of the
chain slider should be 30-50 mm. Rotate the rear wheel to find the
place where the chain is tightest. Adjust the drive chain if it has
too much or too little slack.
NOTE
In muddy or humid conditions, the mud gets inside the chain
increasing tension and may cause the chain to break. To prevent
this, adjust the chain to 30-50 mm of space between the chain
and rocker arm whenever necessary.
