Looks like you're using Ducatis spec's and yes your readings look good.

Opening Rocker

Inlet, mm/in. 0.10-0.12
Exhaust, mm/in. 0.12-0.15

Closing Rocker

Inlet and exhaust, mm/in. 0.03-0.05

But it does depend whose spec's you take to measure by. I did put a post up that covers a few peoples different spec's: http://www.ukmonster.co.uk/monster/s...ad.php?t=56856

What I also found was that when the new shims turned up they were anything up to 0.16mm out from the size that they said they were and I ended up spending a lot of time with wet and dry paper on a glass board sanding them back into spec'!!
