Ok guys, I don't think I've missed anything,.......BUT....

going by more than 1 parts fiche listings, the fill plug gasket is part# 07119963130 12mm x 15mm

That's what I ordered and that's what I got. No problems with supplier, they sent what I asked for.

What I took off of the bike appears to be 14mm x 18mm and the fill plug is also 14mm. Kind of bigger than the listed 12mm plug.

Anyone else ran into this problem?

Hi, Scott,
It's been a couple of years since I did anything to a K1100, so I don't remember the size of the gasket. The "130" part number does sound familiar, though. I will confess, I have changed fork oil on the K1100 and reused the fill plug gaskets. There isn't too much torque on them, and after reusing them, I never had any leaks.
Ride Safe,

That's my problem now they won't seal anymore, and I don't want to tighten the plug to the point that it strips out. I probably will try some type of pipe dope on the gasket and see if that helps seal it.

They have been tightend somewhere along the line to the point that they are not round anymore, and I think that is part of the problem why they won't seal.

Hi Scott, I highly recommend just replacing parts 1 thru 4 on Max BMW fisch Model: K1100LT Diagram #31_0323 (or 7,8,9,& 4 depending on how you look at it.

screw plug x 2
gasket ring x2
spring retainer x2
and large o-ring x2

$100 later and money well spent vs the head ache of leaking forks.

Just sayin' Cool

I think I understand what may have happened in the past with these things.

It's possible that someone sripped one or both, and instead of replacing them like I probably would have, or as Shog's suggested, they tapped them out to larger 14mm and used the 14mm size plug(the same plug used for the final drive fill) and seal ring(14mm x 18mm).
As these seem to be the size that I pulled out it only made sense to me.

ORRRRR....... Bmw mfg'd these spring retainer caps with the 14mm size plug & seal ring, and didn't bother to change the parts fisch data........after all BOTH my '96 and '97 have the larger plugs in the fork caps.

I'm going to buy some of the larger seal rings, now that I know what part # to order, and I should be a-ok.
