====Often forgotten: Checking the oil screen====

You should pull the oil screen, which is under the smaller round cover just behind the oil filter on the bottom of the motor. Once you take the 5 bolts and the cover off, the screen is held in by the rubber bushing around the edges - you can 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.

Once you take the 5 bolts and the cover off, the screen is held in by the rubber bushing around the edges - you can gently pull it out with your finger. If it's very stiff to remove (and most are), tap the cover gently sideways with a rubber mallet once the bolts are removed. Oil flows through it from the top, so you MUST remove the screen to clean the top side.

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.
