I took off my DL-650 hand guards, removed the clutch and brake levers, cleaned the hinges greased em up, performed the 'clutch mantra'. Pulled the front calipers, cleaned EVERYTHING with soapy water and a toothbrush, pulled the caliper slides off, cleaned, polished, and re-greased. Put it all back together, and ended it with a brake bleed.
adjusted pre-load up because I've gained a little weight...
Been at least 2 years since I did that and man I didn't realize how stiff my clutch was getting!
