I and others have complained about some clutch fade with the 07. I do not abuse the clutch at all 2 stroke different story. I admit the clutch fade has gotten better with time put on it. If you look at the basket with the whole clutch pak installed there is enough room for one more plate. Take off the first fiber and look at the clutch hub there is plenty of room for a steel plate. I am going to run another steel plate back to back in the center about the 8th position. I was looking at part#s the 07 YZ250 HAS THE SAME PLATES (2 STROKE) If you go back to 06 with the 450 and 250 (2stroke) it is a different part# They are just thinner but will work. A KX OR RM OR CR MAY EVEN WORK. If you have a extra plate from a different model it may work,just see how it mounts on the clutch hub. I am going to run a steel plate off of a YZ 250 2004 IT SHOULD FIT different thinkness but it will work. My buddy has extra plates off his YZ ,If I am lucky they are steel that year. Hopefully running one more steel plate will take some of the heat away and improve on the clutch fade. Remember since the pak is going to be thicker it will push the pressure plate away from the push rod.You will just need to pick up some slack in your adjustment . I will get back If there is a improvement or if it does nothing,but I would think we have something here.
