It seemed like time to stop being "visitor" and join the ranks. My current driver is a 1988 K75S showing 51K. It's had a color change, from faded red to metallic blue, had the rear drive swapped for taller gears, and is now waiting for its (sorta) new engine fairing to be painted while it does its level best to reject a Rostra cruise control installation.

Welcome!  Is "Dakota" the Sioux word for "white pickup truck with duals"?  I was out there a couple years ago and they were as plentiful as the bison used to be.

It's permissible to have a silver truck, but they're normally not brought into town.

How did you go about changing the read drive for taller gears. I to have an 88 K75s in red and always felt the need for higher gears.

What is the ratio you installed?

I took the easy way out and replaced the entire rear drive. I think the one I got was from a K100RS. It's a 31/11 ratio (2.82:1), but they came in others - 2.91 and 3:1 that I can remember. I had planned on the 3:1, but this became available and has worked out well for me, as I rarely have a passenger. I believe all the K100/K75 drives - except for the K100RS 4-valve unit - are interchangeable, and since the speedo counts rear wheel revolutions there is no induced error. As I remember from running the numbers at the time, my 4th gear now is the same as 5th was with the 3.20 gears. It made a noticeable but tolerable hit to the acceleration, and it's more relaxed on the road.
