I know you can remove the valve core on a Schrader, but is the passage wide enough for the Stans to not gunk up in there? Every attachment I've seen to dump the Stans in the tire threads onto a Presta.
edit: Apparently Stans makes a combo tool that removes both cores. I guess there is enough space.
