Introducing "Claudia" a 1986 K75c
« on: July 11, 2017, 12:01:54 AM »
A couple of weeks ago I traded a cranky old British bike for Claudia.
Since then I have been lurking on this forum picking up all the information I needed to refresh this 30k mi former German beauty queen.
So time to introduce myself: I am a motorcycle hoarder. This is my first Sport Tourer, everything else I own goes from uncomfortable to "chiropractor needed". On the plus side I enjoy doing all my own wrenching and this has given me the opportunity the refresh my L-Jetronic knowledge. So far:

Changed all the fluids, including the forks that got a Belray 7wt oil. (It now glides without sinking every time I hit the brakes). This bike ranks just above my Guzzi in oil filter removal pleasure as it requires 7 less bolts to reach the filter.

Tightened the head bearings to remove some very slight head shake.

New fuel filter and proper submersible lines.All new external fuel & vacuum lines (how many SAE standards do you really need? And CARB too?!?). These were 30 years old and only showing minimal signs of cracking!

Replaced the rusted out center stand with a very nice used one of slightly different design. Question: excellent quality everywhere except here, was this a very early attempt at sourcing from China?

Removed mouse nest from under the air box, along with 1/2 lbs of gravel bits. This took longer than changing the fuel lines. Does all the gravel end up here every time you go off roading?

New air filter replaced something that shriveled solid from age.

Checked valves, two need adjusting and the removal tool is on the way.

Rear splines were done by the previous owner less than 1000mi ago and I plan to check them soon when I get a chance. Once I have the valves adjusted, I will dial in the throttle bodies for balance at idle.

I put in a 400mi day Saturday on sometimes winding roads.. we are talking SE Minnesota here.


The bike is a silky smooth ride. Handling is brisk in a 1980's sort of way, breaking more than adequate and overall experience a pleasure. I have started to think that travel on a larger scale in quite possible....it came with very nice gen 3 hard cases.

If nothing else....I have kept Claudia from becoming an old cafe racer or even worse... a scrambler!

Welcome to the asylum from the land of OZ. Treat her with care and respect and she will serve you well. You might want to go over all her electrical connectors with Deoxit especially the temperature sensor. I also smear a bit of heavy silicone grease around the connectors stops the ingress of air and water which leads to corrosion and bad connections. You need to keep all the rocks and gravel, after a few years you should be able to redo your driveway.

Is that an exhaust bra or a foot cozy?

Are you implying Claudia needs a bra? Claudia is naturally supported!

What you are seeing is heat reflective material on the exhaust shield to protect the luggage. Looks stockish to me.

A friend had one of these in the late eighties, at the time I stepped off my Ducati 900ss and on to his k100rs and my first thought was boredom and car like why would you want one? A motorcycle that you can just get on and feel confident with immediately? ....well 30 years later I see the world very differently!

I'm disappointed then. I thought exciting new ground had been broken for the aftermarket but I'm accustomed to being disappointed when I put on my glasses.

Welcome! May you and Claudia have a long and cordial relationship.

Welcome to the forum Marco, nice looking C, which I'm glad to see you've saved in more or less stock form. :2thumbup:   I'm just north of you in Little Canada, which is kind of like Canada only smaller. :hehehe
