Fair bit of hoop jumping with BAT. Lots of picture uploading. About a hundred listing fee. But must admit, those images (and pundit banter) can inspire some buyers to stop 'sitting on their hands.' If detailed and running well, 10k not unreasonable. Just a waiting game. Ever shrinking pool of potential individuals who could cope with these beautiful but brutal machines, plus repair and maintenance options becoming limited.
I spent well over 10 for my "excellent condition" example and a ton of time and money putting it in rideable shape.
CDI 2/3rds operational. Rust with rusty fuel in tank. Leaking calipers (repainted by 'restorer' but corroded internally), Leaking engine oil seals right side. Wires on connector block hanging by a thread. Loose fork pinch bolts. You name it.
Lots of guys can make them look pretty...Mine just happened to be the color I was after and not ridden much, mostly due to lack of expertise, even many years ago. But it was clean....
