The next time you swap in a new tire it is probably a good idea to replace the old rubber valve stem with a new metal one. I use BikeMaster 151402s on my 3-spokes.

Good idea, Duck. Also, for those contemplating 90 stems for easier access, they do not work on the front wheel because of interference with the brake calipers. I have a 90 stem mounted on my rear wheel but found that it no less accessible than a straight valve.

I have 90 stems on both wheels and have had no problems and dealing with the 305mm discs on a K1100 is much easier and on the rear wheel I have angled the stem back about 45 which makes a access a bit easier.

Rick, I'll be putting new rubber on My K100RS this year and I am seriously thinking about 90 degree stems. Do you have a link to the ones you are using?

This is the guy I got them from in Brisbane. I bought 8 of them a few years ago and progressivly fitted them to all the bikes. I cant imagine they were anything special, they look to be the same as the stems I bought but 2mm could make the difference. You could fit them so they are angled a bit for clearance.

I didn't get a repair kit but it was the only link I could find.

Rick, I see the stems that you referenced above have much shorter shanks than the ones I had fitted. That must make all the difference. My tire specialist was unable to find much selection in 90 stems so I was stuck with what I could get.
