It goes super lean at 12000rpm where the power dips off too, perhaps it is clutch slipping?

Power curve looks nice and smoothe though which should make it nice and ridable

The clutch slipping won't make it go lean. I would think that the dip in the curve is a result of the leanness. Perhaps going up one size on the mains...

But other than that the power and torque curves look nice.

that dip in the torque curve could well be clutch slip, it's right at the peak torque

here's mine on Kev's Dyno for comparison

I wouldn't feel bad, Steve (StephenRC45 blamed the clutch for the dip), he knows a thing of two about v4's.
I'm still waiting for someone to tell me where to get this Motul 9100 stuff from ;)
I couldn't wait for success, so I went ahead without it.
