Checking chain and sprockets for wear (Aprilia RS125/3)

0

Visually inspect chain, front and rear sprockets looking for:

• Damaged chain rollers.
• Loose chain link pins.
• Dry, rusty, warped or seized links.
• Exceeding wear.
• Missing O-rings.
• Exceedingly worn or damaged sprocket teeth.

Warning!

• If chain rollers are damaged, chain link pins are loose, renew the drive chain and the front and rear sprockets as a set.
• The chain should be lubricated frequently, especially after finding any dry or rusty components.
• Lubricate and repair any warped or seized chain links.

Check the chain tensioner roller (1) for wear.

Lastly, check the slider that protects the swinging arm for wear.
