Question Valve adjustment

Im adjusting the valves on an Africa Twin does anyone know if the spec for exhaust valve clearance is measured between the valve and adjuster or between the cam and rocker arm.

Thanks for the info thats a big help. If you have the manual can u confirm the clearance specs? I have
Intake 0.16 + or - 0.02mm
Exhaust 0.23 + or - 0.02mm
Are these correct?
Thanks

Exhaust 0.23 +/- 0.02 mm (0.009 +/- 0.001 in)

Valve Shim Size

Any one know what size valve shims the ATwin takes. Hoping they are standard 9.48mm size...

I'm trying to find definitive size information as well...I'm 99% sure the shims for AT are 9.48mm same as the ones for several other bikes including their 450 motocrosser. My Suzuki DR-Z400S used that same size, so I already have a full set. I'd sure like to see it in an official Honda document, but I haven't seen that yet.
