How to troubleshoot a Honda Monkey 2021 when the starter motor works but the engine won't start?

  Jo HarrisonJul 28, 2025
  If the starter motor operates but the Honda Motorcycle engine does not start, begin by checking the correct engine starting sequence. Ensure there is petrol in the fuel tank and verify that the engine stop switch is in the correct position. Also, check for a loose battery connection or battery terminal corrosion. If the PGM-FI malfunction indicator lamp (MIL) is on, contact your dealer as soon as possible. If the problem persists, have your vehicle inspected by your dealer.

What to do if the PGM-FI malfunction indicator lamp (MIL) is on in my Honda Motorcycle?

  Sarah AndrewsAug 3, 2025
  If the PGM-FI malfunction indicator lamp (MIL) comes on, it indicates a potential issue with the engine emissions control system or engine misfiring. To prevent damage, avoid high speeds and immediately have your Honda Motorcycle inspected at a dealer. In case of engine misfiring, park the vehicle in a safe place, away from flammable items, and allow the engine to cool for at least 10 minutes. If the malfunction indicator lamp blinks again when restarting, drive to the nearest dealer at 50 km/h (31 mph) or less for inspection. Driving with the malfunction indicator lamp on can damage the emissions control system and the engine.

  If the ABS indicator stays on, your Honda Motorcycle brakes will function as a conventional system, but the anti-lock function will be disabled. Reduce your speed and have your vehicle inspected by your dealer as soon as possible. If the ABS indicator does not turn off at speeds above 10 km/h (6 mph), also have your vehicle inspected.
