Here's what I found after getting it in my garage.
This 91 has a few issues before it's a rider, but I think they can be sorted out without too much difficulty. The first thing the seller told me was, the left case lid is missing. Could be a challenge to find another, but I'm sure one will appear sometime. He also said the fuel gauge didn't work. Okay... neither does the rest of the cluster, save for the speedometer...oh and none of the lights work either...

The engine starts and runs fine, a bit clattery on cold start... I did sneak it around the block before making the buy. Checking the coolant, well it was really low... I poured in almost half a gallon of Peak long life premix. But the system looked clean, no scale, and there was no puddle on the ground after a good warmup and an overnight sit. The fuel tank was clean on the inside, I added about a gallon of fresh fuel, some B-12 and some TCW3 oil. I also added some MMO to the crankcase, the trans and clutch on my other two Kawi's shift a lot better with it. Oil change with Rotella T6 is in the near future.
The bike had obviously been down on its left side at some time, possibly a lowside, there are scuffs on the crash bars and the center stand pedal is ground down on one side... it looks like there should be another lever for the first stage of the center stand, but it's not there. Other damage to the left side includes a missing fairing extension, the inner fairing on the left is broken below the speaker all the way across...and a scuff on the 'point' of the left upper fairing. There is also what appears to be battery acid damage on the left side of the engine and upper frame tube, nothing some cleaning and painting can't solve. The existing battery is one year old according to its label.
The radio looks like it's mounted funny in its opening, but it works! Looks like two screws that hold it in place are missing. Its 'frame' needs to be reinstalled...The rear speakers are bungeed down, that should be a fairly straightforward repair. Looks like the handlebar switches need cleaning, most started working after some cycling. Also, the bike still has its intercom cable, and it came with two matching Shoei 3/4 helmets both equipped with the 5 pin intercom system! Haven't tried them yet, but seeing them made me think of some couple in the past sharing good times on this bike, now in need of some TLC... somebody cared for this bike enough to equip it with Markland footboards, backrest and hitch.
The choke cable is in need of lube or replacement, very high effort to operate... also, the bike will crank with the kickstand down in gear and the clutch out, and there is a place for a kickstand switch but no switch.... a dangerous thing, I'm thinking the clutch and kickstand switches have been bypassed. Need to sort that out.
The headlamp aim control is stuck.
The suspension still has air in it... 8 psi front, 32 psi rear. The rear shock on the left has slipped its bushing on the final drive, a nut and washer should solve that. Tires aren't in terrible shape, but that Harley front tire has gotta go

Needs a rear brake rotor, somebody used a lot of rear brake. But none of the calipers are leaking. The frame tube along the exhaust that has the hitch attached to it is rusty, need to treat rust and paint. Also, missing an exhaust tip on the right side.
Other body bits so far: one of the quick release pins for the false tank is missing, and both of the bright chrome covers have broken tabs where they insert into grommets, maybe some ABS primer and glue will solve that.
So, my short list after one night is: Lights and cluster issue, center stand, switch cleaning, choke cable, rear rotor, safety switches, case lid, speaker mounts, left side bits damaged in crash, right side exhaust, fix shock bushing, fluid maintenances, etc.
And a lot of LUBING CLEANING and POLISHING along the way
