Sounds like these old Indians are a bit of a mystery to just about everyone! I just found it interesting that the frame is stamped as a 64 Interceptor when the bike is registered as a 58.
I must say it has been an amazing adventure so far trying to figure just what exactly I have and the whole restoration process. I've learned so much these last couple months and I know that there is so much more to learn. I don't think my wife is quite as thrilled as I am though. Every time I put on my shop clothes she says "Oh. Going to the garage to work on the bike? See you at midnight." LOL
I'm pretty confident that once I can afford that electronic ignition conversion and get that installed, I'm going to have a great little gem of a bike that will be handfuls of fun! And I can't thank everyone on this forum enough for all the help you have been, so thanks again.
