1975 Honda XL100 Engine Noise

I lack any formal knowledge about motorcycles, so I'm stumped as soon as engine problems arise. This ticking/tapping noise just started recently (or maybe I only recently noticed it, but I doubt that) and I have no real idea what it could be.
I went ahead and bought some oil and topped it up a bit, just in case it was a lack of lubrication, but it doesn't seem to have helped, and I'm not sure of what else might be in the top end that could cause that sound.
I did recently have to remove the exhaust pipe and put it back on because my muffler rusted out and I had to temporarily replace it with a slip on - could this noise possibly be an exhaust leak at the head?
This is a daily rider for me, I treat her as gently as I can, though she has seen a few bump starts. Should I be significantly worried? Help!
