No, by the way you described it I do not think this is normal. With the little detail, it could be that your clutch just needs to be adjusted. Since it is the second day you had it (new??) I would just take it back to the dealer and have them adjust it under warranty and make sure everything in the tranny is tight. Also make sure your forward/reverse selector is fully engaged forward.
If it is not under warranty it is really easy to adjust. Just follow the clutch cable down and you will see an adjusting bolt (right where it goes by the crankcase vent tube). Specs call for .20-.39 inch free play in the clutch lever before it engages.
If this does not help give a little more detail about the sound and when it does it the worse.
