Just installed the clutch kit on my 2009 KLX 110. The kit itself is easy to install, the directions in "Tech Data" tell you exactly what to do. It says to actaully remove both clutches from the bike but all you really have to do it take the shoe from the primary clutch. The bike now has more power than before and really hooks out of the turns. From just buying the bike and finding this site I've spent alot of money here and haven't been disapointed yet. I reccomend one of the billet clutch covers to give it some extra pop in the cosmetics. LOVE THE PRODUCT, FIVE STARS!!
