So I was installing my new throttle tube. Finished the install and fired her up. Weird exhaust sound right away. Ran for around 10 seconds. That's when I realized I had left the rain muffler plug on. Now the bike sounds kinda off. A tapping sound of sorts. I have a video but it's hard to hear the sound right. What could I have messed up in the engine by blocking off the exhaust with that plug. God I hope I didnt screw this motor up.
