Does this sound normal? If not what's wrong?

Sounds like it's bogging to me (rich). Other wise seems ok.

Seems A OK to me. Its the nature of a 2 smoker with a slight ping in the top end, if it was piston slap you would know it.

Well the bogging is due to that I took this video while it was warming up. But now that I know the sound is normal I can stop worrying that I'm going to blow it up. Thanks guys
