Depends on what the smell actually is. I know it's not helpful but that's the best diagnosis that can be given.

It shouldn't be a problem. If you've broken it in property then it should be fine.

It could be the clutch if you were beating on it, launching, agressive shifting, etc.

To be honest, I don't think it should be an issue unless the smell is happening all the time. Then it is reason to be concerned.
