I need to change the oil in my bike but i cant find the oil filter. Can anyone tell me where it is located?

I have an 81 honda CM400 it has been sitting for a few years and i just decided to get it back out. I put in new plugs fresh fuel and battery. I run it for a few miles but it still runs pretty rough even with a quality fuel treatment. Im not sure what the plug gap is supposed to be so maybe that is ...
