Honda Activa 6G BS6 Not Starting
Technical Garage Team
3 February 2026
Is your Honda Activa 6G BS6 giving you trouble?
You press the self-start, the engine cranks, but it just won't start. Or maybe it starts, but the mileage has dropped drastically, and the scooter feels "heavy" or jerks while accelerating.
If you have already checked the battery and spark plug, the problem is likely hidden inside your fuel system: the fuel injector.
Symptoms of a Bad Fuel Injector in Activa 6G
- Hard Starting (Morning Trouble): You have to press the self-start multiple times.
- Missing / Jerking: The scooter feels like it is "coughing" or missing beats when you throttle up.
- Sudden Stalling: The engine dies suddenly at traffic signals or when you slow down.
- Low Mileage: A massive drop in fuel efficiency (from 45 kmpl down to 30 kmpl).
- Black Smoke: If you see black smoke from the exhaust, your injector is leaking fuel.
The Solution: Cleaning vs. Replacing
Many mechanics try to clean the injector using petrol or air pressure. The Truth: Cleaning only works for minor dust. If the internal coil is weak or the nozzle is damaged by water, cleaning will NOT work. You will face the same starting problem again in 2 days.
The Permanent Fix? Replace it. Installing a new, original quality fuel injector restores the perfect fuel spray pattern. Your Activa 6G will start in one touch, and your mileage will return to normal immediately.
