How to Adjust a Noisy Motorcycle Small Chain?
2 Answers
Motorcycle small chain noise adjustment requires operating the tensioner adjuster to achieve chain tension. The specific steps are: 1. Loosen the fixing screw; 2. Rotate by hand to loosen the screw halfway; 3. Use a flat-head screwdriver to rotate the tension shaft clockwise to loosen it; 4. Rotate counterclockwise to lock it. Precautions for using motorcycle chains include: 1. Regularly clean the motorcycle chain during normal riding, and apply special lubricating oil after cleaning; 2. Ensure quality when purchasing motorcycle chains, preferably choosing original factory parts.
I've been riding motorcycles for over ten years and have encountered the chain noise issue several times. I remember my old Yamaha would rattle loudly whenever I accelerated. First, find a flat surface, put the bike on its main stand or side stand, and check the chain tension: use a ruler or your finger to measure the up-and-down movement at the midpoint. If it exceeds 20-30mm, it needs adjustment. Then, locate the chain adjustment nuts on the rear axle, loosen them slightly, and turn the adjusters symmetrically on both sides to gradually tighten the chain. Don't overdo it at once, as it might damage the bike. After adjusting, spray some dedicated chain lubricant to reduce friction noise. When washing your bike after riding, remember to clean the chain mud—accumulated dirt can also cause noise. For safety, test ride after adjustment. If the noise persists, visit a repair shop to replace the chain. A severely worn chain might slip, which is dangerous at high speeds. In short, it's not difficult to do it yourself—a basic toolset costs just a few dozen bucks.
