This noise is normal and I think most people experience it. There was a thread on this previously but it may have been deleted in the system crash.
Mine does exactly the same thing except it does it every time I take off while the clutch is slipped, just for a very short time. I also can hear it with ear plugs. In the earlier posts many people said they had it also.
I first noticed it at around 1700km (I bought the bike with 1600km on the clock). My bike is now up to 8000km and it is still there. I don't think it is any problem.
The smell you noticed is probably the hot exhaust, in my opinion. I have smelt it a lot, often just after turning the engine off. Because of the catalitic converter the exhaust is extremely hot and stays hot for a long time after shutting down, unlike other older bikes I have owned. It smells like something burning or a slipping clutch or similar, but there is nothing wrong. It is worse if it has just been raining and some road grime and water has touched the exhaust.
Others may have a different opinion but I am sure it is nothing to worry about.
You probably also notice a bit of vibration and rattling noises when in neutral and also a fair bit of noise and vibration from the transmission on overrun, to the point of being annoying. You soon forget about these things and just enjoy the ride. The bike is fantastic so don't worry too much and ride!
