How to Tighten Honda SP Shine Drop Chain Step by Step (No Noise After Fix)
Welcome to Rajesh Technical Blog. Today I will show you how to tighten Honda SP Shine bike chain step by step so that it doesn’t make noise later. Many Honda Shine riders face a common problem — a loose or dry chain that creates a “khad-khad” sound while riding. If you ignore it, this small noise can damage the sprocket, reduce mileage, and cause jerky movement. Let’s fix it easily at home.
🔍 Why Does the Chain Make Noise?
In most cases, the drop or knocking sound comes when the chain is either loose, dry, or unevenly adjusted. Continuous dust and lack of oil make the chain links stiff. Over time, the rear wheel also gets slightly misaligned, creating vibration and metal hitting noise. So, it’s not just about tightening — you must clean, lube and align it properly.
⚙️ Tools You Will Need
- 12mm and 14mm spanners or socket set
- Chain cleaner or kerosene
- Brush and dry cloth
- Good quality chain lubricant spray
- Measuring scale or small ruler
- Bike centre stand or paddock stand
🧰 Step-by-Step Process to Tighten Honda SP Shine Chain
- 1. Park your bike safely: Place the Shine on a centre stand on flat ground. Turn off the engine and keep the gear in neutral. The rear wheel must rotate freely.
- 2. Clean the chain first: Before tightening, clean your chain thoroughly. Spray chain cleaner or use kerosene with a brush. Rotate the rear wheel slowly and scrub every link. Wipe it with a dry cloth. A clean chain helps you see its condition better.
- 3. Inspect the sprockets: Look at the front and rear sprocket teeth. If they are pointed or broken, change the full chain set (chain + both sprockets). A damaged sprocket never runs smooth even after adjustment.
- 4. Measure current slack: Press the chain in the middle between front and rear sprockets. Standard free play for Honda Shine is about 25mm–30mm. If it moves more than that, you need to tighten it.
- 5. Loosen the rear axle nut: Use a 14mm spanner to slightly loosen the rear axle nut. Don’t remove it completely — just make it free enough to move the wheel back and forth.
- 6. Adjust the chain tension: On both sides of the swingarm, you’ll see small adjuster bolts. Turn them clockwise to tighten the chain. Turn both sides equally so the wheel stays straight. After every half-turn, check the chain slack again until you reach the right level.
- 7. Check wheel alignment: Look at the alignment marks on both sides of the swingarm. Both adjuster marks must be equal. If not, your rear wheel will sit crooked and create noise later. Use a measuring scale to double-check both sides are same distance from the front pivot.
- 8. Tighten the rear axle nut: Once you get the correct chain tension and alignment, tighten the rear axle nut properly. Use good force or a torque wrench if available. Loose axle nuts cause chain drop again.
- 9. Lubricate the chain: After tightening, spray good quality chain lube on the inner side of the chain while rotating the wheel. It reduces metal friction and prevents sound in the future.
- 10. Test ride: Take a short test ride around 2–3 km. Listen for sound while accelerating and decelerating. If you did everything correctly, the chain will run smooth and silent.
💡 Pro Tips for Long Life Chain
- Clean and lubricate your chain every 800–1000 km.
- After every long or rainy ride, wipe and re-oil the chain.
- Never over-tighten — a tight chain strains bearings and gearbox.
- Replace chain and sprocket together when you see sharp or broken teeth.
- Keep the chain guard in good condition; it reduces dust entry.
⚠️ Safety Precautions
- Never touch or adjust the chain when the engine is running.
- Always use a stand to avoid bike movement during repair.
- Wear gloves and keep fingers away from the sprocket area.
✅ Final Result
After following these steps, your Honda SP Shine chain will run smoothly without any noise. Regular maintenance keeps your chain strong, improves pickup, and enhances overall ride comfort. Remember — the secret to a smooth Honda Shine ride is proper cleaning, correct chain tension, and lubrication.2025/11/glamour-bs4-bike-drop-chain-sound.
🚩 Conclusion
A noisy chain is not a big problem if handled early. Tighten and align it properly once every 1000 km and you will never face a chain drop again. Take care of your bike like your best friend — it will always give you smooth performance and peace on the road.
