Has anyone found a replacement tire valve stem for the front wheel of a 2003 K1200GT? The brake disks make checking and adding air pressure more difficult than it should be, especially on the road. A 90 degree or even an angled stem would be better. I have tried the 90 degree screw-on extension but it is also too close to the disks. All the aftermarket 90 degree one I have found are too small for the hole in the rim.
