I also was in the process to register my recent acquired motorcycle as a salvage vehicle with the DMV and so I had to get the CHP to inspect it (VIN # verification) and a brake and light inspection/certificate from a DMV certified service center.
I called the SF CHP to schedule an appointment, but the soonest they can fit me is about 4 weeks out (because CHP does VIN verifications ONLY on Weds). So I decided to call Redwood City and Marin since they are the next closest to SF. Marin CHP told me their schedule was wide open today and thus I booked and appointment.
While I was there for the VIN check, I mentioned to Officer Silva that I also needed a brake and light inspection/certification but I had a lot of trouble finding a certified service center. I called the DMV and Auto Repair Consumer Affairs, and all they did was, they gave me a list of service centers for cars but were unable to confirm if they are certified to do motorcycles. After some digging on BARF I found this tread and the mention of a 76 Gas station in Castro Valley. I told Officer Silva it was a bit far to ride all the way from SF and asked him if he knew of any other licensed shop nearby. He gave the info for two places:
Fernando's Auto Repair
35 Medway Rd.
San Rafael, CA 94901
(415) 460-1708
I called them and spoke with Elva. She said they are licensed to do motos and so I went there. It took about 20 mins and I was done and on my to SF DMV with $75 less in my pocket.
The other place I didnt call, but if it is closer to some of you, then you may want to look into it.
Excelsior Auto Clinic
86 Suite F Hamilton Drive
Ignacio, CA
(415) 883-2347
Good luck!!
