I was very surprised when I recently bought my first ST1100, with 96K on the clock, that it was still running the
factory original valve stems. I would have thought that at some time during one of its many new tyre swaps, the
owner may have opted to fit 90degree stems to help with checking pressures. I bloody hate tyre valves on bikes
that just make it so difficult to check and adjust tyre pressures when it is such a critical part of motorcycling.
What have you got ? I previously used on another bike, the screw on 90 degree extensions which remained on all
the time. I read somewhere that the screw on one's should only be used to check pressures +/- and then unscrew
them. I can understand this but I never had a problem.
What works for you?
cheers and happy travels
