I am liquidating a large collection of these bikes from the 60's for a relative. Some are quite rough and others have been restored. There are thousands of OEM new and used parts available. I do not have titles for all the frames and have had some trouble getting the DMV to title these bikes because I cannot verify the year of manufacture. I have been told I either need information form Honda or an expert opinion. I need help in determining year of manufacture. Additionally, I have a substantial project in front of me regarding sale of the parts. I am hoping for some advice regarding how I can match an OEM part with number to a particular model of motorcycle. I am looking at selling these parts online through various forums and eBay. I have had considerable success with an S90 project over the last month or two. Thanks.
