Check the pressure plate for warpage and small cracks. I had a friend with a CRF that had some weird clutch issues and the pressure plate would warp when it heated up.

How 'bout we throw some punctuation in there, and make things easier to read?

One of the differences between the '07+ and the '06 is the number of plates; the '06 had more, and had fewer problems. To change this in yours, you might consider converting to the older 9 plate clutch. To do this, you would need:

  • The '06 pressure plate
  • The '06 springs
  • the full set of '06 plates (plain plates are a different thickness)
  • AND the '06 release arm (moves the plates farther to make up for the extra plate)

I did the 06 hinson setup on my 07 and love it...Definitely seems to work a little better, and seems to be way less "finicky"...It seemed like it was difficult to get the stock clutch dialed in, and once you did you'd have to adjust it again the next day...I don't seem to have that issue with the hinson, just dialed it in once, and it's been great since...

What exactly is the release arm?? I looked at the schematic on bikebandit.com for the 06 clutch and just wanted to make sure that I was gonna get all the right parts.

On Yamaha's fiche, it's #20, PN: 2S2-16380-00-00, and they refer to it there as "push lever assembly"

Last Question!! Now will the release arm/push lever assembly pull right out of the motor??? or do I have to get into the motor and get it out????

You will need to remove the longer, innermost clutch push rod.

Was the Hinson worth the money? Was it a noticeable difference?

I've got about 40 hours or so on the clutch, and it's been perfect every step of the way...Hasn't worn hardly AT ALL (I can prove it with pics of my hour meter and the interior of the clutch next time I open it up)...Adjusted the clutch only a few times after the first few rides, and have now tightened the allen bolt on the asv clutch adjustment nice and tight...Something I couldn't do with stock as it constantly needed adjusting...

So is it worth $1000? Depends on your wallet...It was a big improvement to the stock 07 setup, which I burned out very fast (it's believed because the fewer plates on the 07+ have less surface area to disperse heat and pressure), and the basket was pretty well grooved up, I'm pretty sure debris in the oil was even a concern...But the Hinson components must be a superior metal, because it shows no signs of wear, no grooves, still works the same after many hours (springs have not worn, plates are holding up great), and the new cable I installed with it has not stretched as did the other (even though it's the same cable, less resistance I guess)...So yeah, I believe over time the product will pay for itself as opposed to having to replace individual stock parts more often...And I've been incredibly pleased with it...
