Results:

 

2007 YZ ex cam, 2008 OEM WR in cam, Ported head, YZ carb specs (+ NCVS needle / 3rd):

 

- Flatter powerband, no flat spots, roll on power is much more consistent, lugs great, revs not quite as great, but I dont' care. Now the powe delivery is more consistent across the rpm range.

- Thottle repsponse is back to normal WITHOUT THE STUPID CRAPPY POORLY TIMED  HOT CAMS. They are full of crap and can't disparage them enough......

- Grinding the ex decomp pin was a PITA. The 1.0mm grind was not enough. Took several attempts. Paul finally got it to 65 psi, and it starts immediately everytime.

- "Swiss-Cheese" mod to the clutch helped a GREAT deal. Better feel, more consistent engagment, lighter feel, and less throw. Motion pro cable is proabaly 20% of that.

- Stock wheels and triples: much better look, much more precise feel to the ride and steering.

-  Trans polishing made the clunky shifting feel dissapear. Feels like a Honda now.

-  Suspension is too non-compliant. I think I am oversprung for sure in the front (.56). 

 

 

Well, it's still has the 'old school' chunky vibratey feel to the motor, and the whole bike feels more 'crude' after a few months on the KTM, but man are the ergos and handling GOOD on this bike.

Very easy to ride slow or fast.
