Does your CD70 make a terrible “kat-kat-kat” grinding noise every time you accelerate? Or worse, has your chain ever fallen off in the middle of a busy road?
These terrifying situations happen every single day in Faisalabad. Most riders blame the quality of the parts. However, 80% of riders ruin their brand-new chain sets within two months simply because they were installed crooked.
Aligning a chain sprocket set on a CD70 is the most important maintenance task for your motorcycle. If the rear wheel is even slightly tilted, the chain will aggressively grind against the metal teeth.
Today, as your master mechanic, I will reveal the exact method to get your wheel 100% straight. By properly aligning a chain sprocket set on a CD70, you will completely eliminate terrible bike chain noise, stop dangerous snapping, and restore your engine’s lost fuel average.
Why Chain Alignment Matters (More Than You Think)
The physics of your motorcycle drive system are very simple. The front sprocket (attached to the engine) and the rear sprocket (attached to the wheel) must be perfectly parallel.
When you ignore this rule, disaster strikes. Here are the extreme dangers of riding with a misaligned chain:
- Sprocket Wear: A crooked chain rubs heavily against one side of the metal teeth. Within weeks, it shaves the thick teeth down into sharp “ninja stars.” When this happens, you must replace CD70 sprocket components immediately.
- Severe Power Loss: A crooked chain creates massive friction. This friction steals your engine’s pulling power. You twist the throttle, but the bike moves slowly, heavily dropping your daily fuel average.
- The Deadly Snap: A misaligned chain heats up rapidly and stretches unevenly. This leads to sudden CD70 chain slipping. Eventually, the chain snaps. When it whips forward, it acts like a steel whip, often cracking the expensive left engine magnetic cover (magnet tapa) into pieces.
To prevent this, you must always start with a Genuine Atlas Honda chain set and install it with perfect precision.
Signs Your CD70 Chain is Misaligned or Dead
How do you know if your mechanic made a mistake during installation? Your motorcycle will always give you clear warning signs.
Look and listen for these symptoms:
- You have to tighten the chain every single week because it stretches too fast.
- You constantly hear a loud bike chain noise that speeds up as you ride faster.
- The chain sits completely flush against the left or right side of the sprocket teeth, instead of riding smoothly in the middle.
- You experience terrifying CD70 chain slipping when you try to overtake another vehicle.
- The bike feels unstable or pulls slightly to one side when you let go of the handlebars.

Proper alignment is the difference between your chain lasting for years or breaking down in a few months.
Step-by-Step Guide: How to Perfectly Align Your CD70 Chain
You do not need to visit a workshop for this. You just need a 10mm, 12mm, 17mm, and 19mm spanner.
Here is the master method for aligning a chain sprocket set on a CD70.
Chain Adjustment blueprint
Technical Logic Path for Precision Alignment
Follow this simple workflow every time you adjust your chain to guarantee a perfectly straight rear wheel.
1. Loosen the Main Axle Nut
Grab your heavy spanners. You do not need to remove the main rear wheel axle completely. Just loosen the large 17mm and 19mm nuts on both sides. The wheel needs to be loose enough to slide forward and backward smoothly.
2. Set the Tension
Look at the very back of your swingarm. You will see small 10mm and 12mm adjuster nuts on long bolts. Turn these nuts clockwise to pull the wheel backward and tighten the chain.
You must establish the correct motorcycle chain tension. Push the chain up and down with your finger. It should have exactly 1 inch of free vertical play. If it is tighter than 1 inch, it will break your wheel bearings.
3. The Secret Markings
This is the most critical step. Look closely at the metal swingarm near the axle bolt. You will see small lines stamped into the metal on both the left and right sides.
Your axle adjuster has a small notch on it. If the notch on the left side is sitting exactly on the 3rd line, then the notch on the right side MUST be exactly on the 3rd line. This guarantees the wheel is straight.
If your old adjusters have stripped threads or bent plates, they will never align properly.
4. The Final Spin Test
Once the marks match perfectly, tighten the main axle nut firmly.
Now, spin the rear wheel hard with your hand. Listen closely. A perfectly aligned chain makes a smooth, quiet whirring sound. There should be no binding, clicking, or grinding noises.
Genuine Honda vs. Premium Mitsuboshi: Which to Choose?
When it is time to replace CD70 sprocket parts, you have two incredible options at BikeSaman. Which one is right for your daily commute?
Genuine Atlas Honda: This is the legendary factory standard. A Genuine Atlas Honda chain set is perfect for the standard daily commuter. It provides exact factory specifications, quiet operation, and absolute reliability. If you ride solo and want original perfection, this is your choice.
Mitsuboshi: This is a premium Japanese brand known for extreme durability. A Mitsuboshi chain CD70 kit uses a harder metal compound that resists stretching under high stress. If you frequently carry heavy cargo, ride double-sawaari, or drive on rough village roads, the Mitsuboshi chain CD70 is the ultimate heavy-duty upgrade.
3 Rules to Double Your Chain’s Life
After you finish aligning a chain sprocket set on a CD70, you must protect your investment. Follow these three Ustad rules:
- Never use acid or harsh detergents: Washing your chain with wheel cleaner or acid destroys the rubber O-rings (if equipped) and rusts the raw metal instantly.
- Stop using burnt engine oil: Local mechanics love pouring black, burnt engine oil on chains. This is a huge mistake. Burnt oil acts like a magnet for Faisalabad dust, turning into a thick grinding paste that destroys metal. Always use proper gear oil or dedicated chain lube.
- Check tension frequently: Inspect your motorcycle chain tension every 1,000 kilometers. A loose chain causes sudden jerks that damage your engine gears.
Protect your new chain from day one.
FAQ – CD70 Chain and Sprocket Answered
Q1: How often should I replace my CD70 chain sprocket set? If you maintain proper tension, lubrication, and alignment, a high-quality set should easily last between 15,000 to 20,000 kilometers.
Q2: Can I just change the chain and keep the old sprockets? Never. An old, worn sprocket has altered teeth shapes. It will instantly stretch and destroy a brand-new chain within a few days. You must always replace them together as a complete set of 3 pieces.
Q3: Why is my chain tight in one spot and loose in another? This means the chain has stretched unevenly due to heavy heat or poor quality. This causes terrible CD70 chain slipping. You cannot fix an unevenly stretched chain; it must be replaced immediately before it snaps.
Q4: Is it normal for the chain cover to rub against the chain? No, absolutely not. If you hear metal scraping against the silver chain cover, it means your chain is either far too loose, or the cover itself is bent and needs to be straightened.
Q5: Do you deliver original chain sets to my city? Yes. Whether you want a Genuine Atlas Honda chain set or a heavy-duty Mitsuboshi chain CD70 kit, bikesaman.com delivers securely and quickly nationwide across Pakistan.
