You should pull the oil screen, which is under the smaller round cover just behind the oil filter on the bottom of the motor. Remove the 5 bolts holding the cover on (8mm socket), and remove it. If the cover is very stiff to remove (and most are), tap it gently sideways with a rubber or plastic mallet once the bolts are removed. The screen is held in by the rubber bushing around the edges - you should be able to gently pull it out with your finger. Oil flows through it from the top, so you MUST remove the screen to clean the top side. Be aware that you may get "some" to "a good amount" of oil dripping out when the cover comes off.

As usual, try to keep your parts organized while you take them off, but if you get confused, just remember that the longer two bolts correspond to the two circled in blue in the photo.

It's not completely necessary to pull the screen, but you'd be surprised how many big chunks of stuff are in there. On Duke's ~~Rally~~ bike there was some trash in the engine before it was rebuilt. So, to be sure he got it all out, the screen was checked at every oil change after the rebuild. There was less trash in it with each oil change~~.. If~~ it hadn't been cleaned, the screen would probably be 60-80% clogged. At the ~~20k~~ oil change there were only a couple small pieces in the screen, so it probably won't need to be checked again for a while.

The composite picture on the left shows a bike that had 8800 miles on it. The goop is most likely gasket sealant from when the two halves of the engine case were assembled. The excess has to go somewhere. The stuff that goes to the inside of the engine sometimes falls off into the oil.
