Drive Chain
82 Servicing Your Honda
Drive Chain
Refer to Safety Precautions on page19.
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 off the ground by placing
the optional workstand or equivalent support under
the engine and check that your transmission is in
neutral.
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)
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.
NOTICE
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).
1. Check the chain slider (1) for wear.
If the wear is 0.2 in (5 mm) or more, replace it.
2. Check the chain guide slider (2) for wear.
Replace the chain guide slider if the chain is
visible through the wear inspection window
(3).
