Thank you all for the welcome and interest.
I am going to follow the advice of my neighbour in Dripping Springs and just take the thing down piece by piece to acquire familiarity with it, and to build basic confidence in my limited skills. I'll put it back together more or less intact just to ensure that I can get it running - at that point I'll have already taken it "down and back again" and should be able to do a better job of the custom plan I have in mind - at my leisure.
I will use this forum to obtain advice and guidance. Also, if I get stuck, I notice that several of you are within driving distance of Wimberley, so if you agree I might ask to draw more directly on your expertise.
I'm a 68 year old retiree doing this for the first time. I have a garage, basic tools, bike lift, air compressor, water hose, LOTS of cleaning stuff (I had a show-grade HD once upon a time, and you never get over that). I don't weld or do machining, but I have access to people who do.
My first question is where to take this as a follow-up thread from Intro. Do I start a thread under Build, or do I take the questions/pix/comments to the subject matter topics?
I'm ready to ask my first questions about wheels and tires (the front is now off), so tell me where to take them so that I'll be in line with forum conventions.
Also, are there on-line schematics and part number lists? Where would I find that? I have located the information on Biker.net, but it specifies that it covers bikes up to 1981. Naturally, mine is an '82, both according to the paperwork I have and according to the serial number on biker.net - it is for sure an XS650 SJ in New Yamaha Black.
I'm assuming that I could use most of the information available there, but if there are '82-specific docs, I'd like to get them. Unless otherwise advised, I'll use the torque settings from the biker.net information.
Tell me where (politely) to take the first round of questions: Build, or Wheels and Tires?
