I am facing "Misfire". But this occurs at a specific case as follows
Rev the engine to >5K RPM, and now leave the throttle. At this stage I am hearing a "POP" sound from silencer.
However this issue is not occuring at lower Rev Ranges (<5K).
Recently I have changed the spark plug/air filter too. I have given the bike to authorized service center too.
But they told like, "Lets try by adjusting the air/fuel mixture." But that is also a failure.
My biggest question is, If the misfire is occurring, it should occur irrespective of the case right? But why it is occurring at a specific place.?
If the ignition coil is problem, then it will raise the problem irrespective of the case right?
Could someone help me, to identify/solve this issue?
