As it was said. Re-shimming the comp is a good way of firming up the front end. It's set deliberately soft so that road riding is nice and smooth.
On Paul's MC21 (Paul@TYGA, not Wrench!) I set up the front with twin stack compression, didn't touch the rebound stack (just the clickers), HRC option springs and 135mm oil height (no spring, fork compressed) with 10W Showa oil. Works a treat for doodling down the street, or fast, back lane scratching. Paul won't go on the track for fear of crashing, but it's more than adequate for what he wants. He's about 100kgs in his togs, ready to rock.
The twin stack offers supple damping at slow speeds, but firms up nicely when things speed up.
