Thanks for the info, from the time I acquired the bike, the adjustment on the clutch arm was pretty much bottomed out, as in the threaded adjuster was almost flush with the lock nut, and I would say that there is approximately 12mm of clutch arm rotation before it engages the push rod, the angles are ok, yes the clutch arm pivot is easily bent, everything lines up well for proper slave to clutch arm function, my thoughts were that if the adjustment was maxed that there is wear that could be addressed and rectified, as I'm sure from the factory they wouldn't have been "cranked" in so far? I will look into the older yz parts to see if I cam locate one or at least the o.e. specs on it, cheers!
