Backfiring and detonation problem
Hello all! Sorry for my grammar(
I have a 2008 Boulevard c50, and for almoust half a year I have a problem with detonation and backfiring. It starts only when the bike is hot, when you try to accelerate fast from low RPMs, you can hear detonation sound from the engine, also sometimes you can hear a pop from the exaust pipe when you ride on middle RPM with no trottle. My pipes and tail light are covered with black soot. I tryed to change the petrol, changed the sparks, air filter, TPS sensor, 3 times I cleaned the injectors, cleaned fuel filters and everything inside my tank. I've tryed octane boosters and fuel injector cleaners, but nothing seems to help. I live in Vietnam, we dont have any qualified mechanics here, so I do it by myself, learning step by step. May be someone can help me? Where to look? What else to check?
