How to Solve the Chain Noise Issue on GW250?
3 Answers
This situation is often caused by the motorcycle being left outside in the rain, leading to chain rust. Applying lubricating oil to the chain and rotating it several times should resolve the issue. Check if the chain case has any dents or warping. If so, it is necessary to completely remove the case and restore the dents or warping.
Chain noise is quite common on the GW250. To address it, first check the chain tension—typically maintaining a 20-30mm gap is ideal. If it's too loose, tighten it using the chain adjuster. Next, clean the chain by scrubbing off grease and dirt with an old toothbrush, then apply chain lubricant (avoid engine oil, as chain-specific lubricant offers longer-lasting rust protection). If the chain is significantly worn or stretched, replace it promptly to avoid the risk of detachment, which is dangerous while riding. I always inspect mine before long trips, ensuring proper wheel alignment, as misalignment can also cause noise. Additionally, clean and lubricate the chain immediately after rainy rides, as moisture accelerates rust and wear. Regular maintenance saves significant repair costs.
To fix chain noise, I usually ride a GW250. If the chain is too loose or too dirty, it starts making noise. The simplest way is to pull the chain to check its tightness; the standard gap should be about the width of two fingers. If you want to DIY, just spray some chain wax—avoid using regular lubricant as it won’t work well. If you’re not into DIY, take it to a repair shop for adjustment; spending a little money is safer. Make it a habit to quickly check the chain before each ride, and clean it if it’s dirty. After riding in the rain, don’t leave it unattended—clean off mud and water promptly to prevent noise buildup. Ignoring this small issue can make the chain worse over time, even affecting transmission efficiency, making your ride less smooth and more fuel-consuming. So, address it early, and learning some basic maintenance is very practical.
