Hello, I have a motorcycle for a year and it has been doing it every time since I bought it. I want to ask if this sound is OK during a cold start. First the loud sound of the cylinder and then the engine speed stabilizes. I don't have a problem with the engine, I just wanted to ask if it's normal?

And my second question is about the exhaust. I have a damaged exhaust and every time I drive in the rain, I feel a burnt rubber. An odor flowed from the exhaust. This condition is always only wet. What could cause it?

Cold start > video <

Thanks guys (y)
