I did mine about two weeks ago. It was pretty easy. This is just a quick guide to go by. I got my clutch from rocky mountain ATV. Or you can get it from the site sponsors or honda. I went with a better set of springs.
SOAK NEW CLUTCH PARTS BEFORE INSTALL.
take off break pedal and rear plasic piece neer foot peg,
take off cover,
take long rod and two washers off,
take plates out,
Check basket to make sure all is looking good,
install new plates (alternate pads and spacers make sure pads on on the outsides of the baskets)
put rod back in making sure to adjust where the clutch cable goes in to make sure it pushes the rod out when pressing the clutch lever,
reinstall two washers that were on the tip of the rod
TQ the springs down to 9 pounds,
install clutch cover, install brake pedal back and rear plastic.
Fill with new clutch fluid (Your choice) remove overfill screw fill till it runs out put screw back in
make sure clutch cable is adjusted right.
Crank it up. (I let mine idle for a bit before i got on it. Then did not ride it hard for a few min. then raped it like it should be driven.
Keep in mind you may not use all the discs that came with your clutch kit.
Refer to your honda manual before during and after install for any questions or ask somebody here.
