How to Fix a Motorcycle Chain That Jumps, Skips, or Slaps
Understanding the Causes
A jumping motorcycle chain can be a nuisance or a safety hazard. Here are some common causes:
Worn Out Chain or Sprockets
A worn chain or sprockets can cause the chain to slip over the teeth, leading to jumping. Check for excessive wear on the chain links, sprockets, and guides.
Stiff Joints in the Chain
A stiff joint in the chain can disrupt the smooth transfer of power, causing the chain to jump.
Loose Chain
A loose chain can slap against the sprockets, which can eventually lead to jumping.
Chain Too Tight
An overly tight chain can restrict power transfer and cause the chain to bind, increasing the risk of jumping.
Symptoms of a Problem
* Chain lash (slapping) * Chain jumping or skipping sprocket teeth * Premature wear of chain and sprockets * Chain breakage * Difficulty shifting gears
How to Adjust Chain Tension
1. Loosen the rear axle nut. 2. Turn the adjuster bolts on both sides of the swingarm to adjust chain tension. Adjust evenly to maintain wheel alignment. 3. Check chain slack and adjust as needed until it meets the recommended range.
Tips for Maintaining Chain Health
* Clean and lube the chain regularly. * Adjust chain tension as needed. * Inspect chain, sprockets, and guides for wear. * Replace worn components when necessary. * Avoid riding with a loose or overly tight chain.
