Hello from new member from Denmark. This spring i bought a '93 K75RT with 64.00 km's on the clock. It is allmost in excelent condition apart from the cosmetics. Have changed the forsk seal and all oils and lubes the FD splines with Guarddog moly. Next weekend me and a friend is going to try to get the tranny of to lube the transmission splines.
I have  previously had several SOHC Hondas that I have restored to running condition so I have experience in wrenching MC's - but my experience with BMW's are close to nonexisting.
I hope to get som advice from searching and posting to this forum over time.
/Jens

Welcome from Oz Jens. If you know your way around a spanner, you are in front of a lot of us when we first got our K's.
Lots of info and friendly chat comes from these guys.
And don't forget the pictures, we love photos and laughing at others mistakes.(quietly of course).
What colour is the KRT, not red I hope.

Welcome Jens good to have you along.
You will find that the BMW drive train has far more in common with a car than any of the Japaneese bikes.
Seeing its a K75 be very careful to pull the gearbox straight back till your friend can gt a hand in to the space and push the clutch actuating rod back away from the clutch. If you don't support it there is a possibility of bending the pushrod.
The K100 pushrod will remobe out the back of the gearbox where the K75 pushrod will not do that and will often stay in the clutch spigot bush and get bent if the box is allowed to get out of line.
Take the gearbox right off and inspect the clutch and rear main seal.

I was a bit aware that the BMW's where a bit different than the japs that i've had worked on the last 30 years. Then again i think the difference is not much bigger that the difference from my first bike a AJS macthless to the Hondas. The old English cycles had their special way of almost everything.
The reason i skipped my Hondas that i loved (i once had 4 of CB500's and CB550's in different states of rebuild) in favor of the K75 is that where i live now i do not have a permanent workshop/shed or garage. So i had to have a more reliable bike and only one at a time. Since ihad the experience in the jap way of doing things it could be funny to try the German way.
The choise of a K75 was based on the factors that I am not getting younger (i'm 58) so that I don't feel the need for the sense of riding a crouchrocket any more. And i would like to have a more touring like bike to take me the 100 km's from our home to the summer lodge or on a three day trip to friends in the other end of Denmark.
After testing different BMW's i fell in love with the smooth characteristic of the 750 triple engine. At the same time i think that on the K75 there is still some things to do for a pavement tinkerer like me - ei there is still mechanics to repair since not everything is electronic on the K75.
Thanks for the advice on the clutch pushrod. I will be carefull.

Thank you. Yes I know my way around the spanner. From what I read in this forum I can se that there are many skilled wrenchers in here. I hope to be able to participate in the sharing of god experiences as well as i'm certainly going to make my stupid mistakes (and maybe post the story). I think that i already have en good understanding of how this bike is put together although i spend most of my time in here to read about how to this and that. Much time as there are so many good postings.

My bike is metallic black  - most of it - as it is a bit cosmetically challenged on the paint - you can't se all the scratches on this picture:

Here's a picture of my latest CB550 in all its glory after my restoration - in the rrear you can se one of the others. They have all moved on to better homes now.

Those are nice photos, looks in pretty good condition. Good luck with it and welcome over here if you feel like travelling a little further.

Don't be afraid to ask any questions, no one will make fun of it.

Dai made another warning too, if you are doing this, make sure you support the rear wheel when you take off the shock, as in make sure you support the swing arm.

Don't let Dai or Comberjohn or me see those Honda Fours........As former owners we might have to come over and help you with the K75..... check them out. However I do get a regular fix as the local Honda dealership where I get my tyres fitted has a CB500-4 parked in the showroom, along with a CB175 and CB250.

I will certainsly ask a lot of questions along the way.

If you should happen to come passing Bagsværd you will be disapointed because all of my CB's are sold of to other owners as have no room for them in the new house. The new owners made a solid promises to be nice to them and keep them i good condition before i handed the license over.

Thanks for the advice regarding securing the monolever from falling down when i take of the rear shock. is there a way to check if the rubbers have already been split without removing the rear end completely?

I am not sure how different the K75 is but I was under my K100 at the weekend and checking out the clutch boot, all seems ok, it was replaced May 2014 but its done a lot of miles since. You can lie on the ground and feel around it but definitely easier with rear wheel off. I didn't go checking the drive shaft one as I will be at that next month-planning a clutch spline lube.

If 88KE is on he might tell you more as he did a lot to his K75 in May before we went to France.

Don't be tempted to take a power washer to the K....they don't like it, especially up the rear end as it will damage the clutch and drive shaft rubber seals.

Another welcome from Oz.  Very Happy  Good to have you along. 

And what's wrong with red?!!!
All my bikes have been red because they go faster!
Actually, only the first was a deliberate choice (new CB175 as a 16 year old.) The others just happened to be red, but shows the wise choice of the original purchaser.

You will find with the drive line rubber boot that when you let it drop 2 sharp edges jamb and cut the boot at the bottom. I have damaged a few and if you clean the surfaces with acetone they can be mended with super glue then I put the mended bit at one side. To be cynical that is so a new section gets damaged next time.
You cant see if they are damaged till you get them out. The clutch pushrod boot isn't damaged by the swingarm but by age and tightening the clamp too tight which cuts into the rubber.

And a welcome on behalf of K mavens here in the US of A!

I have mainly been restoring Yamaha RD's and purchased a K100 to go on longer rides and take my better half with.

Looking forward to seeing your posts!

The latest three bikes i have had was som variant of black. The new K75 i black as well. If I had bought a Guzzi LM3 it shurely should have been red  Smile

Thank you for all your welcomes. I will move over to the "normal" forums with all my questions.

Velkommen Jens,

Jeg så først dit indlæg nu, jeg har ikke været meget på nettet i den seneste tid.
Jeg tror du bliver glad for bimmeren, jeg har selv en K75Rt med en fortid ved det tyske politi, og den elsker jeg at køre på. Den er stadig i de orginale farver.

Mvh
Peter

Some greetings in Danish.

Hello from the U.S.  As you can see in my signature I also have a soft spot in my heart for Honda.  Won a lot of enduros on XL125's.  Wonderful little bikes.  A total of over 18,000 racing miles and never saw the inside of an engine.
