I just changed the clutch on my 06 YZ450 and thought I would post the pics from it. 1. I drained the oil and removed the rear brake pedal. 2. I loosened the clutch cable adjuster and removed the clutch cover. 3. I removed the 6 bolts holding the pressure plate on. 4. When removing the pressure plate be sure not to loose the little steel ball 5. Remove all the clutch friction plates and inspect the clutch boss for marks in the fingers. If there happens to be scars in the fingers remove the boss and replace it or you can simply prolong the replacement by taking a file to the fingers(not recommended) and knocking down the scars as a temporary fix. 6. Here is the specs for the clutch friction and steel plates 7. I know a safe measure is to soak the new friction plates in oil before you install them. Some clutch plates dont need to be soaked in oil before install but these specific ones do. 8. Install the new clutch starting with a friction plate and you should end with a friction plate. 9. reinstall the pressure plate and new springs but if you are going to use the same springs then here is the spec sheet 10. The pressure plate and clutch cover should be torqued to 7.2ft-lbs 11. install the clutch cover, install the rear brake, adjust your clutch cable as needed and add oil. Once the bike is warm the manual tells you to slip the clutch a few times to seat the clutch plates. The clutch job took 45mins. to complete from start to finish. I hope this helps and keeps you roostin!
