I have some odds and ends off my 1985 K100 that I no longer need, maybe one of them will be useful to you.
Pics on request, any reasonable offer will most likely be accepted. Paypal OK, or postal money order. ACTUAL COST OF POSTAGE ADDITIONAL, or better yet come pick up your parts in Rockland County, NY.
SOLD
1. OEM rear shock. Low miles (if you believe the odo on my bike), no leaks or problems whatsoever. $402. OEM seat. This is the old (1985 and earlier) style, with grab handles part of the seat. Upholstery is torn and there is some rust on the pan, but could be useful for a project. No mounting hardware. $30
3. Dust cap for bearing on bottom tree p/n 31 42 1 234 509 Brand new nothing wrong with it, I bought two when I only needed one. $2
4. Left side integral case. Cosmetically not great but it got my stuff from NY to Arizona and back. Has the new style locks (not the flat kind). $50
5. A pair of RT style handlebars. $45
