I wouldn't just give him one price...I'd give him options.
The touring package is an incredible find (Wish mine had it) and while I'm not even finding any completed auctions on eBay for it, I'm sure there are people who would pay decent money for it.
However, if you hike the price to compensate for the open-market value of the F&S Touring Package, your market constrains itself to people who want a 23-year-old VN750, who recognize the F&S kit for what it is, who want it, and who are willing to pay that for it when it's connected to said 23-year-old VN750.
You would probably sell everything faster and for more money if you removed the touring package and sold it separately. That doesn't require someone who wants to buy your motorcycle to ante up for a touring package that they may or may not want, nor does it require someone who wants the touring package on a 2006 to buy an '87 motorcycle with it.
