How to Adjust a Motorcycle Chain?
2 Answers
Correct methods for adjusting a motorcycle chain are as follows: 1. Timely adjustment is necessary to maintain the chain's tightness between 15mm and 20mm. Regularly inspect the cushion bearing and apply grease as scheduled. Given the harsh working conditions of this bearing, lack of lubrication can lead to significant damage. If the bearing fails, it may cause the rear sprocket to tilt, leading to side wear of the sprocket and chain in mild cases, or chain derailment in severe cases. 2. When adjusting the chain, besides aligning with the chain adjustment marks on the frame, visually check if the front and rear sprockets are in a straight line with the chain. This is crucial because if the frame or rear wheel fork has been damaged, relying solely on the adjustment marks can be misleading, as the actual alignment may already be compromised. Therefore, this inspection is vital (it's best to remove the chain cover during adjustment). If any issues are detected, immediate correction is necessary to prevent future problems and ensure safety. 3. When replacing the sprocket and chain, ensure to use high-quality products with good materials and precise craftsmanship (usually available at authorized service stations). This helps extend their service life. 4. Regularly check the fit between the rear wheel fork cushion rubber sleeve and the fork and fork shaft. The lateral clearance between the rear wheel fork and the frame should be tight, with smooth vertical movement. This ensures the rear wheel fork and frame function as a unit without compromising the rear suspension's damping effect.
As a seasoned motorcyclist with over a decade of experience, chain adjustment has become second nature to me. I always remember to check for chain slack before and after each ride—the standard is about 1 to 2 centimeters of vertical play. If it's too loose, I address it immediately. I can handle it at home: first, turn off the engine and wear gloves for safety, then use a wrench to loosen the rear axle nut and adjust the chain tensioner gradually until the slack is just right. After adjustment, it's crucial to ensure the chain is properly aligned on both sprockets; misalignment can wear out parts and even cause unstable riding. Finally, tighten the nut and take a short test ride to confirm smooth operation. Don’t forget to apply some chain lubricant—it can extend the chain's lifespan by two to three years. I make it a habit to check every 500 kilometers, and with this routine, the chain lasts longer, and I ride with peace of mind, free from worries about sudden breakage. By the way, investing in a good wrench and quality chain lubricant costs little but saves a lot of hassle.
