If you want big bucks you could strip the entire bike down to parts. eBay post them all and cut the cost by 30% what everyone else is selling them at and still make $10k on parting out perfectly good working parts.
The trans alone is about $600. Tank, $700, fenders $900. Engine block assembly with the heads verified good for $2500. Frame 300, front end $1200. So on and so forth. You can always double or triple the worth of it by parting it out.
But if time and storage is a value to you. Sell it for $4800. Done
