Why is my GAS GAS 125 TXT GP 2019 Motorcycle exhaust backfiring?

  Nicholas HansenAug 15, 2025
  Your GAS GAS Motorcycle exhaust might be backfiring due to: * The presence of carbon in the combustion chamber, which requires cleaning. * Poor quality petrol or the wrong octane rating, necessitating draining the old petrol and refilling with new petrol with a higher octane rating. * A spark plug in poor condition or with wrong specifications, which should be replaced with a new or more appropriate one. * Damaged exhaust system gaskets; check the exhaust system and replace the gaskets if they are not in perfect condition.

  If your GAS GAS Motorcycle engine won't run, there are several potential causes: * If the motorcycle has been inactive for a long time, drain the old fuel and refill with new fuel. * A dirty or wet spark plug can be dried or replaced. * If the engine is flooded, vent it by accelerating to maximum and operating the kick-start pedal 5 to 10 times, then try starting it again. If it still doesn't start, unscrew and dry the spark plug. * For an incorrect air/petrol mixture, clean the fuel tank ventilation and adjust the air filter duct. * For seized components like the crankshaft, cylinder, piston, crank pin bearing, or transmission assembly, it's best to go to a specialized workshop.
