Just thought I would share this everybody. I recently replaced my levers and clutch cable with a parts unlimited power lever set(12 bucks) and a motion pro ultra smooth clutch cable(30 bucks). Before the swap my clutch was pretty stiff despite having a new clutch kit and constantly lubing the cable. When installing the new motion pro i removed the clutch arm and coated it with a thin layer of waterproof bearing grease and also the little notch where the cable goes into the arm.
While installing the lever I also coated the pivot bolt and the holes in the lever. This may all seem like common sense but I'm tellin ya the difference is night and day. I think I reduced my clutch pull by about 50%. I have my buddys 03 kx250 in my garage right now and mine is easier to pull than his. Hope this helps somebody
P.S. For 12 bucks the levers are an awesome buy. They are black and look good on my bike. Already survived a crash and a couple of tip overs
