You should see a fairly intact perforated pipe going all the way through. It usually starts to rust and burn near the weld seam that connects it to the front end piece. As said give it a tap and see if stuff drops out or if you hear rattling from the inside. There always is some soot buildup in the pipe but if it looks excessive or there is lumps of it in there your air/fuel mix is way too rich or some other reason why all is not burning (oil leak)

Left side outside of the motor? I meant more in the way of valve stem seals or piston rings, an external oil leak will not affect the insides of the exhaust. But if the sooting is minor then it's perfectly within normal spec.
Nevertheless SOMETHING is burning that shouldn't but I'm still leaning towards soot that has come loose or a leaking seal between the pipe and the muffler that causes the change in the running sound.

Black soot is okay. If nothing that looked like rusted metal came out then the pipe might be okay. The baffle is a tube with holes in it that you should see when you look in the pipe.
Explain the oil leak issue a little more. How much oil is coming out? This is not normal with a Honda engine they are usually pretty tight and don't leak. How many miles on this bike?
Pull the plugs one at a time and look at them. I say to do it one at a time so you don't get confused about which wire goes where. Assuming that you are just learning so this is the easiest way to keep track. You are looking for a difference in the plugs. Report back with what you see. If there is a difference take pictures and post them. This can tell a lot about how the engine is running and if there is a problem.

Shut the fuel petcock off and take the fuel line off. Remove the gas tank. Then you should be able to get to the plugs. You can loosen the bolts on the radiator to get more access but not necessary. Don't take the radiator off...way more work than you need to do.
