Looking at a few different options on a tpms with the cap that goes on the valve stem. External style like the Hawks Head . http://www.tpms.ca/MOTORCYCLE.html. All of them say to use a metal valve stem only but as you know our Tenere has a rubber stem. Anyone ran one of these on a rubber stem with success or is this a no go? I've done some reading on here and it seems with our style of wheel there isn't really another metal valve stem that works? Or is there one that works that I'm missing?
