OK, so I noticed when I first purchased my 95 K1100rs that the little "BMW 4-Valve" logo spark plug cover panel was not on my bike. So I've been looking for one for some time and finally ran into one at a decent price.
When I went to put it on, I noticed that a 5mm screw wouldn't start, so I figured it was a 4mm. When I appropriated the screws, to my surprise, they slid right into the hole. $%#@$, too small! So what the heck?! 5mm too big and 4mm too small. Thinking 4.5mm now.
But WAIT.... I checked the holes in the valve cover and to my surprise, they had never been tapped for bolts....
So now I'm wondering, did the 1100rs even have the cover installed in the FIRST place? I mean the belly pan covers everything for all intents and purposes. Did they not put that panel on the RS? Anyone know?
