Since "the financial manager" allowed me to buy a parts bike, to put my 88 parts bike back together, I had to agree to put the 87 up for sale... So $10,000, and I can tell her I posted it! JUST KIDDING. 
I would sell it for $3200 OBO, and am interested in trading it for a different K bike. A running, or almost running K1100RS, a K100RS or a K75RT. Partial trades OK; if trading up, it cant be by much... or I'd be sleeping in the garage. 
The bike is a 1987 K75S I just recently bought, before discovering I am old enough that the S faring is not big enough for me to hide behind. I can't believe I got old enough to admit that!
I did add the Areoflow smoke tint windshield, but if you prefer the stock height Gustafson screen. I have not even ridden it with the new windscreen yet!
It has a progressive suspension 412 shock on the rear, so I assume it has their springs in front as well. Fairly new Pilot Activ shoes on 'er as well. All the bikes cosmetics are in good  shape... no road rash or damage, although not owned by someone that enjoys polishing all the shiny bits - either be or the PO. Had LED taillight conversion that goes through a flashing sequence before going solid. Truthfully, I have not done much with this bike except ride it to work several times. Seems to be running fine to me, for the short time I had it, and same for the PO. He had it longer, but has a stable of 4 other bikes as well, so didn't ride it a ton either.
Some minor paint problems, leading me to believe it is a respray in the stock color. Did not hold up well around gas cap. But looks great from ten feet back. Headlight high beam switch frozen, but that should be fixed in next few days. Either cleaned up, or swapped with 88 parts bike.
I have also swapped out the seat with a dual corbin, or I have a stock seat that needs a recover. negotiability exists!

Hey, all.
I found a K75C with a Pichler Faring I’m very interested in, but he’s getting out of bikes completely, so not interested in a trade. If I can get $2500 for my 87 S, that will leave me enough to get new shoes on the C, and find out if I like that faring. So...
PRICE Drop to $2500. Ya still only get one of the three seats, but you can pic the one ya like the best. I’ll even throw in the stock seat off the C, if it works out!

And a brand new smoke areoflow

Hi Dan. Where are you located. I’m in NSW Australia. 
I have a K1200R. Registered that I’m willing to talk about as a swap.

Hey, Jimmy D!
  Glad to hear from ya. Seems like a LOT of the active members here are from OZ. While the 1200 would be a trade I'd love to look at, (I've never ridden one) the shipping to / from Alabama would prolly get a mite expensive! 
  Sadly, I'm in the US, 
  Sounds like I'd fit in over there, better than I do 'round here, but y'alls gub'ment wont let us bring the furry kids with us, so my wife says no way
         D. J .P.

Hi Dan - I was wondering if your k75 was still up for grabs. Thanks!

I had not had the chance to update any info. , and it is still for sale. Has a new front tire mounted now… one of the folks that looked at it did a better tire inspection than me, and found the good looking tire on the front had some scary sidewall cracking going on! Also ordered a new rear tire, but am getting more of the tread worn off the rear before mounting the new one!
So still priced at 2500, but with new tires.

Just saw you are out in TX. If you have your heart set on your first K being a Mystic Red K75S, mine would be an excellent choice! And there is (or was) an RT out there that caught my interest, so…
I found I got old and want more faring. Since I look a lot, I can offer you advice on some ads out there ( but red is faster!)
My wife says I’m the worst salesman ever. But I like helping folks. Course I’d be glad to help talk ya into mine as well!
