Can the noise from a motorcycle's small chain be adjusted?

Loosen the fixing screw by hand, turning it until the screw is halfway released. Use a flat-head screwdriver to rotate the tensioning shaft clockwise to loosen it, and rotate counterclockwise to lock it. At this point, start the vehicle for testing, and the chain noise will disappear.
Speaking of motorcycle chain noise, I've encountered this issue several times myself. The rattling sound is mostly caused by a loose or excessively worn chain. Adjustment is completely feasible—I've fixed it myself before. First, you need to lift the rear wheel of the motorcycle, then use a wrench to loosen the rear axle nut and locate the chain tensioner. Turn the tension screw to adjust the chain tension properly—the chain slack should be kept between 1 to 1.5 cm. Too loose, and it can fling around; too tight, and it accelerates wear. After adjustment, the noise usually disappears. However, if the chain is severely aged or the sprocket is damaged, you might need to replace the parts, or the problem will only worsen. Regular maintenance is also crucial. I spray chain lubricant every 1,000 km or so to prevent rust and keep it clean. Chain noise isn't just annoying—it's a hidden hazard. A broken chain can cause a crash, so safety comes first. In short, address the issue early to avoid major repairs.
