I’ve been lurking and learning while idly scanning Craigslist for a possible K bike. Given the kind of riding I tend to have time for these days (freeway commuting), a brick seemed like a great choice. I finally found my project and picked it up today. A cosmetically rough 87 K75s.

yeah, that looks a little ruff. Lots of body panels for an S on ebay, except the battery covers. But cosmetics are only skin deep, hope it runs good!

After a quick oil change and a change of gas in the tank (the pump and hoses all look to be in good shape) I used a car battery to jump the dead battery and after a few minutes of huffing and puffing, it started! Blew a horrendous cloud of smoke, but started and idled.
The brakes are not working, there’s an oil leak (or 2), the rear brake fluid reservoir is cracked and leaking, and fork seals are suspect. Also the tires are old and hard, and most of the critical rubber components on the outside are shot (vacuum port plugs, crankcase breather, etc...) but I’m putting together a wish list from a few places and really excited to get it back on the road.

Oh, and it was only $500.

Welcome from another new member/new K75S owner.
We will probably meet again online, stabbing each other in the back over parts :)

Bargain welcome to the asylum from the land of OZ. With the K75s be aware that failure to install the "C" clips that secure the rear of the fuel tank can result in the side covers making a bid for freedom. Depending on a few variables, like how tight the "C" clip grommets are and how much fuel you are carrying hitting a large bump can allow the tank to jump. The result is the covers making a bid for freedom, these covers are getting hard to find. :dunno
Regards Martin.

Thanks Martin! I guess the PO was aware of that because the side covers are in a box with the extras that came with the bike. There are no c-clips however.
I spent all day tearing it down and cleaning as I went.
I thought the front master cylinder was toast, but a few hours in the ultrasonic cleaner and it’s making good pressure.
The tank has pinholes however, and I’m torn between getting them welded and using the permatex putty sealant. I’ll probably go with the putty and look for a decent tank on eBay.
The mount for the gauges and headlight has broken mounting tabs, and I started looking at turning it into a naked bike, but apparently the bracket is only ~$40 from the dealer so it may stay as a proper ‘S’ for now.
The inside of the air box/plenum has a lot of oily residue, I figure from blow by, so the motor may not be as healthy as I was hoping. Or it’s just the residue of nearly 100k miles.

The k75s is the pick of the litter in my opinion and getting rare in OZ. Keep it's appearance stock. Had mine 20 years and will never sell it.
Regards Martin.

dittto, except I've had mine 31+ years. Way too many getting chopped up and parted out.

Well if I did go with a standard headlight, nothing would be irreversible. No cutting, no drilling. But I’d like to ride again, I haven’t had bike for the last year, and that was the first time in 27 years I’ve been without one. The bodywork needs repair, and it’s going to be a while before I can afford a decent respray.

Welcome! Your K75S is indeed the pick of the brick litter. It's light, nimble, has a good riding position and will be super reliable once the neglected items have been addressed. If it has any weak points at all, it is the windshield that throws turbulance right up at your helmet. My solution was to find a cheap windshield and shorten it by about 5" which allows my head to be in the clean air above the turbulance.
eBay is your friend for parts. There seems to be nearly everything you need. It's the first place I go whenever I need something. I just crashed my K100RS, totalling the fairing, frame and almost everything but the engine and drive train. So far, there are only three parts I haven't been able to get on eBay that will cost me a total of $25 from Max BMW.
Speaking of Max BMW, their parts fiches are an excellent resource for finding part numbers, cross references, and dealer prices. If you haven't already, I would suggest that you bookmark this link:

Good luck with your new bike. You got a great deal on it.

Thanks! I’ve got a parts order out, so now I wait and keep cleaning. The block is a grotty mess, I assume because the PO didn’t have his tank vent lines hooked up.

Can I snip the steel bands on the air box and replace them with hose clamps? I’d really like to clean the oil residue out.

No hose clamps are too wide. OEM ones will cost you an arm and a leg. There are Suzuki ones that fit. And you can find them in various sizes on line they are called Oetiker clamps and require a special tool to crimp them. Although I believe some have modified end cutting plier or nail pullers successfully. There are heaps of posts on the subject.
Regards Martin.

Yes. You can follow Martin's suggestion or you can get them from BMW. Here are photos from MAX BMW'S online parts fiche.

Thanks. Great info! I suppose I should’ve searched first. :)

48mm Suzuki band clamps part number 09402-48208 will also work and may be readily available from multiple sources. They come in black as well.

Geez Rob your eyes must be really good to type that small. I going to see if I can borrow a seeing eye dog that can read. :hehehe

There Martin, fixed it for the rest of humanity without "Micro-Vision" (Copyright RBM 2017) :hehehe
[rant] The Motobrick forum software really bugs me when it mangles text like that without notice or warning. I have no idea how to stop it from mangling text either.[/rant]

Drats Rob just ordered a Labrador now I'll have to cancel it.
Happy New Year regards Martin.

That's not fair Chaos what's the Honourable Minister for Finance and Recreation going to say?? Maybe she won't notice it. :dunno

That's tempting, but outside my budget at the moment. I think I'll plastic-weld the cracks and replace the missing mounting hardware and ride it for a while.

Beware the majority of the K75's fairing is made out of compressed fibreglass.

Good philosophy. After a deer hit destroyed my fairing I rode sans bodywork for a couple years until I found a deal from beemerboneyard.com on a nearly complete S fairing.

Howdy and welcome.
I drive the same year and model. "totalled" it past August...miraculously walked away. In 40 years and dozens of rides there's none Ive enjoyed more. The fairings are worth the effort. In my opinion they give mine a timelessly beautiful look. Feel free to contackt me for whatever insights. Cheers and happy new year...
