Back in AZ, Eastside Performance was a shop like this. Owners are KZ fanatics, TJ and his awesome wife Pam (I'm sure many here know them better than I) but they helped me out with my LM III and the since repealed AZ motorcycle emissions test standard

. Great folks.
Here in California there are so many good bike shops like MGC, RTL Moto and others that I feel lucky. Real knowledge, in person. Mark at MGC and Sean Fader (has his own place now - RTL) have helped me out so many times and given advice that comes only with experience, cant even count the times.
Can't put a price on shops like that.
