Was thinking about adjusting handlebars just not sure what to expect from adjustments? I imagine there is not adjustment for the seat or foot pegs without an investment of money?
The bike is all original mint with 29k. I really don't want to do anything which cannont be easily undone.
Thanks in advance
Bryan

I have an 85 k100.Attached is an image of the bike in your first post.

Brian's 1985 K100.jpg (88.07 kB . 600x450 - viewed 410 times)If it is the one you're discussing in this post, it has the standard height seat—no adjustment. The handlebar looks like an RT touring bar. It might even be attached to a riser. You can move the dash out of the way by removing two screws then loosen the bar clamp screws and rotate the bar to find a more comfortable position. BMW bars are 22mm, not 7/8" if you're contemplating a different bar. Flanders American Side Road cycles is a good site to visit to select handlebars for BMW bikes. Rise and pull back are two terms that relate to handlebars. The Flanders site has an illustrated explanation of the terms.
Here is a useful site (http://cycle-ergo.com/)

According to the regristration it is an RSIt has been modified to be a half-naked touring bike. Google 1985 K100RS and you'll be seeing bikes with fairings, lower bars, and streamlined windscreens.

the handlebars on the thing are very high... i would rotate them down to where your banjo bolt clears the tank... try that out... and slowly raise them up a little at a time until all is good...
need better photos of how those bars connect to the tree... grip angle is all freaky and just wrong... it looks like bar back whack...

AT: I did a quick search, must have chosen the wrong keywords. I am guilty of not spending much time on that.
Johnny: I rolled the bars back about 1,1/2 inches. Still seem to be putting a lot of weight on my palms. Much further back and I will be touching the tank. Tried to take some pictures but apparently, I have to resize the image's. I Don't want to spend much money but I imagine I can find a used seat that places the business part of the saddle a little further back. Not sure what keyword or kind of seat to look for though.

I am 6.1 bout 212 lbs. In the most comfortable (for my legs) position I am sitting on the halfway hump (rider/passenger) part of the seat. I also seem to be leaning heavy on the handlebars making the fingers on my throttle hand numb.Is the "leaning" you describe a leaning rearward from wind pressure that pains your hands and arms? I'm around 6'2" with a 35" sleeve length and 34" inseam. My bike has no windshield. My bike's handlebar is both lower and also more forward than yours but I hardly put any weight on my hands and arms at city and highway speeds because when I ride, I use wind pressure as a cushion to support me as I lean forward. That relieves pressure from my hands and arms until I'm exceeding the speed limit.I Don't want to spend much money but I imagine I can find a used seat that places the business part of the saddle a little further back. Not sure what keyword or kind of seat to look for though.
I wonder how much an original fairing cost?
You'll need to have your seat modified by an upholsterer to get the feeling and position you think you want. The aftermarket has no bolt-on options for the K75 except for products from custom seat builders who use your bike's seat pan as a base. There are aftermarket cushions that might level the surface so you can slide further rearward. If Jack Riepe adapted to this bike and has had adventure after adventure, there's hope for most of us.
The original fairing wasn't exactly a bolt-on option; it was a design system. It and its associated parts could be installed on a naked bike at considerable expense but they are rarely found now.
A side profile photo of you seated on the bike would help clarify your situation. Resizing a photo should be much less effort than changing the handlebar.

The upper body position is also more forward lean, with airflow helping support.
Core body strength is a factor.
I am 6ft and ride stock setup k75s and k13s. Zero issue with pressure on hands, in fact there is almost no pressure at highway speed.

I do have some subtle body quirks. I ran over myself with a riding mower when I was a kid (another story). Because of my age and how long I was off of one foot and leg. My right foot is smaller (9) than my left (12.5) my right leg is also shorter which skews my back. I don't think that would have any effect riding other than using the rear brake pedal (I am missing my big toe and part of my foot). Nobody could tell from watching me. It just has a subtle way of sneaking up on my when doing certain things. Like golfing, (nothing to pivot on) or when I swim, (I tend to swim in big right-hand circles.)
Soo I will read, I will learn,,

Read his stuff. Retrained my brain and muscle memory. Been taking a 15 to 30 mile ride each day.
No more numbness in hands, back is great and I am looking foward to getting on the bike 100 times more.
Thanks
