There are lots of gunks accumulated inside the cover due to chain lube and road dirt. Time to clean it up real good. I don't remember who said this: "A job worth doing is worth doing right". So I cleaned it all up with kerosene and WD40. That is the difference between a home mechanic and a professional mechanic. The pro doesn't clean it. I am better.
It's also time to pull out that clutch rod, clean it and put a light coat of synthetic grease on it. Just don't squeeze the clutch at this time while the cover is off, or you can pop out the clutch piston.
