Drive Chain
Replace the drive chain (page 115 ) if it
has damaged rollers, loose pins, or
kinks that cannot be freed. Lubricate the
drive chain (page 114 ) if it appears dry
or shows signs of rust. Lubricate any
kinked or binding links and work them
free. Adjust chain slack if needed.
. Inspect the front and rear wheel
sprocket teeth for excessive wear or
damage. If necessary, have your Honda
dealer replace a worn sprocket.
