Hello friends, welcome to Rajesh Technical Blog. Today I will tell you about BS6 Splendor Plus Bike Injector Changing Process – Step by Step Guide
Riding a bike smoothly depends a lot on the fuel injection system, and on your BS6 Splendor Plus, the injector plays a crucial role. Over time, injectors can get clogged or malfunction, causing poor performance, misfiring, or lower mileage. If you’re facing such issues, changing the injector yourself can save time and money. Here’s a complete DIY guide to change the injector step by step.
1. Why Injector Replacement is Important
The fuel injector ensures the right amount of fuel is sprayed into the combustion chamber at the correct time. A faulty injector can cause:
- Engine misfiring
- Rough idling
- Reduced mileage
- Hard starting
- Black smoke from exhaust
Replacing a damaged injector ensures optimal engine performance and smooth rides.
2. Tools and Materials Needed
- Before starting, make sure you have these tools ready:
- Screwdrivers (flathead and Phillips)
- Socket set with ratchet
- Wrenches (10mm, 12mm)
- Injector cleaner (optional)
- Replacement injector compatible with BS6 Splendor Plus
- Clean cloths/rags
- Gloves for safety
- Fuel line clamps
> Tip: Keep a small container to catch any fuel spills to avoid accidents.
3. Safety First
Working on the fuel system involves petrol, which is flammable. Follow these precautions:
- Work in a well-ventilated area
- Keep fire or sparks away
- Wear gloves to protect your hands
- Turn off the ignition and remove the key
- Disconnect the battery negative terminal for safety
4. Step 1 – Preparing the Bike
1. Place the bike on its main stand on a flat surface.
2. Ensure the fuel tank is half-empty to minimize spillage.
3. Remove the seat and side panels to access the fuel system.
> Pro Tip: Take pictures of all connections before removing anything — it helps during reassembly.
5. Step 2 – Disconnecting Fuel Lines
1. Locate the fuel injector near the intake manifold.
2. Use fuel line clamps to prevent fuel leakage.
3. Carefully disconnect the fuel line connected to the injector.
> Safety Note: Keep a rag under the fuel line connection to catch any petrol drips.
6. Step 3 – Removing Electrical Connector
1. Identify the injector’s electrical connector.
2. Press the tab and gently pull the connector off.
3. Avoid pulling the wires; only pull the connector body.
> Tip: If stuck, a small flathead screwdriver can help, but do it gently.
7. Step 4 – Removing the Injector
1. Remove the mounting bolts or clips securing the injector in place.
2. Carefully pull the injector out from the intake manifold.
3. Check the O-ring on the injector for damage — replace it if needed.
> Important: Do not use excessive force; a stuck injector can be gently twisted to remove.
8. Step 5 – Installing the New Injector
1. Compare the old injector with the new one to ensure correct type.
2. Lightly apply engine oil on the O-ring of the new injector to ease installation.
3. Insert the injector into the intake manifold carefully.
4. Secure it with the mounting bolts or clips.
> Tip: Ensure the injector sits fully and snugly — loose fit may cause leaks.
9. Step 6 – Reconnecting Electrical Connector
1. Push the electrical connector back onto the new injector until it clicks.
2. Make sure the connection is firm and there’s no loose wire.
10. Step 7 – Reconnecting Fuel Line
1. Remove the fuel line clamps.
2. Attach the fuel line to the new injector securely.
3. Ensure there are no kinks in the fuel hose.
4. Double-check for tight fit to avoid leaks.
11. Step 8 – Reassembling Bike Panels
1. Reattach side panels and seat.
2. Ensure all screws/bolts are properly tightened.
3. Check that wires are routed correctly and no pinch points exist.
12. Step 9 – Testing the Injector
1. Reconnect the battery negative terminal.
2. Turn the ignition ON (do not start) and check for fuel leaks.
3. Start the engine and let it idle for 2–3 minutes.
4. Listen for smooth idling and check throttle response.
> Tip: If engine runs rough, double-check all connections and O-ring seating.
13. Step 10 – Post-Installation Tips
Ride gently for first 50 km to let the injector settle.
Use high-quality petrol to prevent clogging.
Periodically clean injectors with approved injector cleaner.
Keep an eye on mileage and engine performance.
14. Common Problems & Solutions
Problem Possible Cause Solution
Engine misfires Loose injector connector Check and reconnect
Fuel leak O-ring damaged Replace O-ring
Rough idle Injector clogged Clean or replace
Poor mileage Incorrect fuel Use recommended petrol
15. Advantages of DIY Injector Replacement
- Cost-effective: Save service charges
- Quick turnaround: Do it at home
- Skill development: Learn more about your bike’s fuel system
- Custom care: Can inspect and clean surrounding components
16. Conclusion
Changing the injector on a BS6 Splendor Plus is not very difficult if you follow the steps carefully. Safety precautions and proper tool usage are key to a smooth DIY process. Once installed, your bike will run more efficiently, mileage may improve, and you’ll experience smoother acceleration and better throttle response.mahindra-bolero-hfap-ingen-fitting.
