If you're going to do some modification to make it yours, I would recommend keeping it minimal. In all of the bikes I've had, I've come to the conclusion that the magic formula for making a stylish but ridable bike is as follows:
1. Tires and brakes. Get the best sport touring rubber you can afford and fit the best quality brakes you are able to finagle. This can run the gamut from just rebuilding the stock system with fresh seals, piston and lines, a higher quality rotor and new pads, to something as ambitious as swapping forks so you can run dual rotors with dual piston calipers. Not only do fancy brakes look sick, but they will keep you out of the hospital if you know how to use them.
2. Update air intake with foam filter element, replace and retain stock design (Air horns are wild, and if you take the stock airbox apart, you see that the factory intake boots are horns encased in a plastic shell)
3. High quality 4-into-1 or 4-into-2 exhaust from a name brand. Retain full baffles to minimize rejetting. It will actually sound better with the baffles too. Good sounds are better loud, but loud alone does not make a sound good.
4. High quality factory type seat with a similar size and thickness. Minor ride position changes for a more contemporary seating position can be very beneficial, especially combined with other *minor* ride position geometry changes.
5. Buy a new set of bars that are SLIGHTLY lower, wider, and less raked back. This will create a ride position that makes it more comfortable to go into an aero tuck on than the stock semi-buckhorn style bars these things come with, but way more comfortable to sit upright on in traffic to save your back.
Other than that it's mostly just refreshing stuff.
You've got a very strikingly beautiful bike in unusually good condition from the look of it. I believe it's your right to do whatever you wish with your own personal property, but if what you want is a flat-tracker/brat, it would just make more financial sense to clean yours up a little bit more, flip it next spring when prices are at peak, then spend your winnings on a ratty "project bike" in the fall. SOmething that's obviously been in a slide so parts like the bars, side covers, tank, seat and lights are all torn up to diminish the value so you can gobble it up.
