Was this an escort or marsheling bike? there's strobes on the side?
Looks like you have a very soild deal, even if it ends up costing you more then $2500,
I'd suggest getting it running and stopping first, then once that's done, starting fixing the cosmetic (and expensive issues)
that will have a better chance of making the wife more happy, or less mad. Unless she's like mine and she know's motorcycles then you can't pull a stunt like that...
But really make sure it goes and stops, then ride it for a while, while cleaning it up. I'd even wait on the shocks unless they are totally gone and are just now springs.
Watch the wiring it could be a mess depending on how the PO wired up all those lights. He might have also wired in a radio as well. Make sure you have a good wiring diagram of the stock bike.
I make copies and add the things I find to to the copy just so I can figure out what's going on.
