Drive Chain
3. Inspect the drive chain for:
• damaged rollers
• loose pins
• dry or rusted links
• kinked or binding links
• excessive wear
Replace the drive chain if it has damaged rollers, loose pins, or kinks that
cannot be freed. Lubricate the drive chain if it appears dry or shows signs
of rust. Lubricate any kinked or binding links and work them free. Adjust
chain slack if needed.
4. Check the chain slider for wear. If the ridge in the center of the slider
is worn, have your Certified Motorcycle Mechanic replace the chain
slider.
5. Replace the drive chain if chain slack is excessive when the rear axle
is moved to the farthest limit of adjustment. Excessive slack indicates
the chain is worn beyond its service limit. To check the chain’s service
limit, remove the drive chain . Then measure the distance between a
span of 86 pins, from pin center to pin center. If the distance exceeds
the service limit, the drive chain is worn out and should be replaced.
6. Inspect the front and rear sprocket teeth for excessive wear or damage.
If necessary, have your
Certified Motorcycle Mechanic
replace a worn
sprocket.
NOTICE:
Use of a new chain with worn sprockets will cause rapid chain wear.
Standard Chain 428x114 recommend using heavy duty type. (HD)
