Anyone know of a good "tune up" mechanic in So Cal? Got my son an 02-WR426 and want to get the mods done, new exhaust and re-jet. A couple of years ago I had local dealers do my 03-WR450 but the 2 dealers I went to couldn't tune it correctly. Finally had is done by a guy in Vegas and it screams! Unfortunately he moved to Nor-Cal.
