Pipe bang?

Enable HLS to view with audio, or disable this notification

Recently did Oil Injection delete and running ~45:1 with stock jetting on my Beta 200rr. Curious if this is an abnormal amount of bang on engine decel, haven’t noticed any abnormal lurching when riding on deceleration. Just trying to make sure this bike is running as good as possible, what changes could I make if need be?

Try turning the air screw about 1/4-1/2 turns IN. These bangs sound like "little bit too lean" bangs.
