BMW do sell them individually, mine are inbound as I found one missing last week. Ordered a couple and the clips for around £30 delivered. I couldn’t find anything online that matched. Sorry I don’t know the part numbers yet. The other one was missing its clip and was just about to disappear. I managed to make a temporary repair by cutting down a footrest pin that was close to the same diameter. As far as I can tell they start to bind up then work out as they twist each time you raise the screen. I have greased them and over the weekend the screen was nice and solid.
on my 2007 RT i had all four screen "arms" break and the screen almost came off when i was riding. i replaced them with steel ones as the original ones go brittle over time and break
I was washing the bike and lifted the screen to the highest position to clean the underside. Noticed that the lower left pivot pin was missing completely. The e-clip was missing from the lower right side pin, but the pin was still in position.
I can only assume that the e-clip has dropped off the left pin and allowed the pin to vibrate loose. Presumably, the right side pin would have followed if I hadn't spotted it and fitted a new e-clip.
Interestingly, both upper pins were still in position and both e-clips were present.
Replacement lower pin is on order, expected next week. I'll remove all 4 pins and clean/lubricate them on reassembly. According to the parts microfiche, the upper and lower pins are slightly different sizes. That's not a sensible engineering approach.
