An air leak could make it over fuel, faulty O2 sensor, and a De-cat can make it smell like that.

What colour are your spark plugs?

If it's got no cat, it will be like a older car which always smell a bit of petrol. Have a look at your plugs, if they look black then you've got a problem. But otherwise it sholud be fine.

They will kick a bit of smoke out anyway at high revs.
