I have a 200cc motorcycle which i use for daily ride to my work for just around 20 minutes only. I always had this problem of having low power after I decelerate using engine brake. Here is the scenario.

When I decelerate using engine break especially in downhill terrain and rev the throttle, there is a change in the acceleration power and the sound of the exhaust. For example, i use only 1/8 of the throttle power usually to attain 60kph. But after the problem, it takes 2/4 to 3/4 of the throttle to attain 60kph on the same gear. Another thing is the exhaust sounds not the usual like it has a lot of air and there are popping sound everytime i use engine brake when it has low power and the normal will come back after some minutes. I dont know whats happening and i already took my bike to the mechanic and explained what happened but he also cant diagnose the problem since everytime i took the bike to the mech, the problem is not present lol. Btw, my bike is just 6 months old. What seems to be the problem of my bike? Thanks in advance !!

Lot's of popping on decel often means the bike is running lean. Is your bike carburated? If so, I would start out by cleaning the carb and checking the jetting.
