You should be well under 11 seconds in the 1/4 mile if you ran it that far. Bike looks good, it has 'one of everything.' Do you know if the engine has had internal work? The radials should be able to make it handle much-better in the curves, and more stable at triple-digit speeds.
You might consider putting another light in-place of the rear grab bar red reflector, which apparently has been removed. It looks like there might be something there now, since it's all flat black, it's hard to see if there is a light fixture there now. Anything you can do to make your bike more-visible from any point is worth the effort/expense. While the replacement rear taillight oval is 'cool,' adding additional lumens to your view presented to others on the roadway just might make an inattentive, texting/talking on their cell driver, realize that you're in-front of them, and they're about to run you over, if they don't get on the brakes

I have a license plate light which has a horizontal row of red LED's above and below the license plate, and amber vertical columns on either side of the license plate, the latter are functional as turn signals, and the former are both running lights and brake lights. It makes a considerable difference in my 'light signature.'
You might take a look at your front calipers and see what composition pads you have. The single opposed calipers/pads used from '85-'92 need help. The cheapest way to do that is to use HH pad composition. Honestly, I'd swap over the front end to a 1993+ 43 mm from your 40 mm. Your rotors will go from 282 mm to 298 mm if you do that, and you also get 4-piston opposed calipers. Don't forget the HH caliper pads. Add stainless steel brake lines, and you have made a significant upgrade in your bike's handling. Leave the OEM early model stored for if/when you sell the bike. The RICOR or Progressive Suspension (PS) cartridge emulators assume damping duties in-place of the OEM slider damping rods, and are adjustable. Then you have the PS front fork springs, another supplier is Race Tech, theirs are sized according to your weight and use. The PS is more of a 'one size fits all,' but many riders use 'em and like 'em.
Sean Morley offers a single side large disc/triple opposed piston caliper for the '85-'92 front end.
Given the $$$$ accessories on the bike now, it's very possible some of that front end work has already been installed.
