Sorry to say this mate but you're discovering what many others have before you and didn't realise. The more you change/bling up a bike from standard the less it's worth.
The biggest depreciation element is colour/paint to bodywork, tank, frame, wheels, coloured break lines etc, then comes anything that's non standard and isn't a direct replacement, screens, exhausts, end cans etc. Things that are good but don't add value like suspension up grades, yes it's an Ohlins shock or Ktech front revalve/cartridge but the bike must have suspension, the fact it's now fitted with 3k worth of AM won't add 3k to the bike. The other big blind hole is tuning, PC, Power plus etc, they don't add value.
The colour of yours appeals to you and possibly to some others, but not the masses, so it could potentially sit in their showroom for months even years!
I always tell my customers to keep all standard parts and avoid colour changes. If they really want to change the colour get a second set of body work/tank and change that, keeping the originals. Come sell on time put the bike back to standard and sell off the painted parts for crash repairs etc.
Racers have been doing just that for years
Put it back standard as far as you can, if you want a trade in. You'd be better off trying to find the other person via a private sale, who likes/wants the colour.
What you thinking of going on to?
