82 Servicing Your Honda
Drive Chain
Refer to Safety Precautions on page 19.
The service life of the chain depends on proper
lubrication and adjustment. Poor maintenance
can cause premature wear or damage to the drive
chain or sprockets.
When the motorcycle is ridden on unusually
dusty or muddy tracks, more frequent
maintenance will be necessary.
Before servicing your drive chain, turn the
engine OFF, raise the rear wheel of f the ground
by placing the optional workstand or equivalent
support under the engine and check that your
transmission is in neutral.
Inspection
1. Turn the engine off, raise the rear wheel off
the ground by placing an optional workstand
or equivalent support under the engine and
shift the transmission into neutral.
2. Check the drive chain slack (1) in the upper
drive chain run midway between the drive (2)
and driven sprockets (3). Drive chain slack
should allow the following vertical movement
by hand:
1 3/8 – 1 3/4 in (35 – 45 mm)
(1) drive chain slack (3) driven sprocket
(2) drive sprocket
3. Check drive chain slack at several points
along the chain. The slack should remain
constant. If it isn’t, some links may be kinked
and binding. Lubricating the chain will often
eliminate binding and kinking.
Excessive chain slack may allow the drive chain
to damage the engine cases.
4. Inspect the drive chain for:
• damaged rollers
• loose pins
• dry or rusted links
• kinked or binding links
• excessive wear
Replace the drive chain (page 84) if it has
damaged rollers, loose pins, or kinks that cannot
be free. Lubricate the drive chain (page 83) if it
appears dry or shows signs of rust. Lubricate
any kinked or binding links and work them free.
Adjust chain slack if needed (page 83).
