Makes sense...I can tell you that this bike is not rare in any way shape or form...just not as common as other bikes...but still not rare.
I've done a few projects over the years, it's not for the feint of heart.
First, I've never met a project that wasn't a mess to start, that's why it was disassembled. Next, parts will be missing and unless you know they bike intimately you won't know till it's time to reassemble -- then finding/buying a pile of odd parts on ebay gets expensive fast. Finally, be prepared to spend more than a good used runner, it rarely ends up any other way.
I still do the odd project, I just do it differently. I always buy a parts bike to match the project, that gives me most of the missing parts, some spares, and a reference sample for reassembly.
Here's an example of a beauty I'm doing right now. It's a one owner garage queen 75 GL1000 Goldwing. I bought it for a friend, it certified as it was. The bike was a bit fugly with it's Windjammer, tail rack, Calfina hard bags, heel/toe and floor board setup. Taking it back to stock looked simple, doff the fairing, bags, and put back the front pegs and shifter so I didn't buy a parts bike.
1) Internals and chrome ring for nacelle $100 (needed after removing Vetter fairing)
2) Footpegs $110
3) Shifter $90
4) Right control $140
5) Stems for returning signals to original location $70
6) Shoulder bolts for rear grab rail, $30
7) Rear grab rail $200 (needed to return signals after removing bags).
I'm at $750 already because I didn't think I needed a parts bike for this one - my bad, I could have picked up a parts bike for $750. Id have one more of everything AND I could polish and paint parts with minimal down time on the running unit.
