I should go to jail, I just stole this BMW!

Hey folks, I was perusing my local Craigslist and this '86 BMW K75 was posted just about an hour before for $500 w/title. Though I've been restoring old Honda/Ducatis for quite awhile, this sucker is all new to me. I'm still trying to figure out what model it is; I think it's a RT model. Seems I'm lucky and got the dual front disc brakes as well. In talking to the owner, it seems his brother bought it to ride down from Mass to here in Texas to visit him, decided to get a fresh paint job on it after arriving, then parked it and moved to Argentina seven years ago. So as far as he knows just a basic tune up and maintenance is all it needs - it's only got 43,xxx miles on it if that makes a difference. I know these K-bikes are known for their longevity though. So, for those BMW lovers in the crowd, what are the first things that I need to do to get this thing back on the road? I've been looking for a BMW bike for awhile to see what all the fuss was about - couldn't be happier with this one!







Can anyone tell me if parts are missing?


Are these pretty good panniers? They must be BMW stock as the key worked to unlock them. They were both full of riding gear!

I think what you have is a K75/RT and Yep , at $500 for a running bike you stole it. Those are BMW bags . They are pretty good but mine were not a 100% waterproof so I always picked my clothes in waterproof bags.

Might want to look into getting the splines lubed since you don't have history on the bike. Other than that and by doing normal maintenance those bikes are bullet-proof. Should be able to get another 75K miles out of it.


I bought a BMW R90/5 about 10 years ago for $300 and rode it home. I thought those deals were long gone but you have proved me wrong.

Yup, that's what I was going to say. It's either going to be expensive to have it professionally done, or very time consuming to do it yourself.

But, it only has to be done every 50K.

Those are great bikes. Probably the smoothest engine I've ever ridden.

And yeah, go turn yourself in. Thief! :)

I'll second that it looks like a K75RT. Also looks like it is missing the lower fairing pieces, but as a bonus you got an after market seat, probably a Corbin.

If it were me, I'd change all the fluids including flushing out all the old brake fluid and then ride it until it told me what it wants. If it has spent much time out in the weather the electrical could be the weak link. If that starts giving you any trouble I'd start by cleaning all the contacts and connections before replacing pieces.

I rescued a K100RT from a similar situation for about the same price a few years ago that was non running due to either a faulty ignition switch or kill switch. Once I cleaned them up it started every time. It now has 146,000 miles on it.

Nice find. Tires,oil/filter,battery,plugs,air filter and ride. Repeat if necessary. Too bad about the seat.

Nice pull!
If it was stored with gas in the tank, don't try to start it without checking the gas pump dampner. The rubber will have turned into goop and will mess everything up.

Score!
To my eye it does look like everything is there. Probably sometime quite soon most of the rubber bits and possibly gaskets may need to be replaced.
Also you might at some point think about head bearings- my old 88 K100 got pretty stiff.

Someone said to listen for funny clanking noises on start up in an older K?
Post it in the "Vintage K Bike Luv" thread here in Old's Cool and ask questions there.

Besides the lowers that has been mentioned the air box snorkel is missing.
May find a rats nest in place of the air filter too.

Go to IBMWR.org and you will find a treasure trove of information.
It is missing the fairing lowers. I had a K100 that I put 147,000 miles on, and it needed 3 valves adjusted in that time. The final drive splines will need greasing, follow the instructions on the forum I referred to. It is not difficult. You may need to replace external rubber bits as they age crack over time if exposed to the elements.
Good luck! They are great distance eaters!
