To answer some earlier posts, I am in Thousand Oaks, California.I have restored several bikes in the past. Here is the last one I did, a '71 Norton Commando:
http://hubpages.com/hub/Norton-Commando-RestorationThe other barn find bike is a Yamaha dirtbike @'74. A buddy told me he thinks it is a 360 that has had a lot of race mods done to it. The VIN is DT1-XXXX but I don't think it is a DT1. Wrong tank for sure. It does turn over, so this may be a runner.
As far as the seized engine goes, I have sprayed carb clearner and WD-40 in the plug holes. No help there. It is definitely in neutral.I have been trying to turn it over using the alternator bolt on the left side of the engine.
I have no Idea who the previous owner was. I am going through the process to get the title. Basically, it is called a lean sale. You apply to DMV for names of previous owners and then DMV requires that you send them a certified letter. They have to come up with the cost for my hauling and storage if they want the bike back. It hasn't been registered for thirty years, so the chances are that whatever address DMV has on record, if there records go back that far, is wrong. After 31 days, if I can show DMV that there was no response, the bike is mine.
