Squish Clearance?

[Anonymous]

As a point of interest, does anybody know what sort of squish clearances the 16V 1100 motors typically have from the factory? This makes a big difference to how hard a motor will run and how hot it gets, which is a significant point for our air-cooled motors.

Hmm, now that I am thinking of it, maybe I will need to stick some solder in and measure mine directly... :?

Second question - can a head be milled with the valves still in place or do valves have to come out? Cams are a piece of cake, but the valves are a PITA to pull for a simple thing like decking.
