Not really, you may have a seal leak.

How does the bike run? With a seal leak, it will tend to run lean...be careful.

Yes, you have a seal leak...replace it with a new one....your seller will help you with ordering a new one, or someone here will give you a part number shortly.

That's a crank case gasket... not a oil seal.
