Best San Francisco bay area shop for machine work?

Ok, so I lost the base gasket on my 2001 YZ426 and it's time for a top end. I have it all apart and need a suggestion on who to send the cylinder to that will do a good job on fitting up a new piston.

Anyone got a favorite shop?




I don't know about the Bay Area (in more ways than one), but down at this end of the state, boring and replating costs as much or more than a new cylinder. If it doesn't need boring, run a ball hone through it and slap in a new standard piston. Otherwise, but a new jug and slap in a new standard piston.

Or go big bore.
