I could see this being true on the non bolt-in type. I know people have had issues with this on FOBO motorcycle tire pressure sensors when using a rubber valve stem instead of metal.
Please elaborate on this, since you know so much about tire inhalers, I'd like to see what you build. (Be sure to send your design to BMW, so they can sell it for $200 )
BTW, I don't spend crazy money on tire gauges. I have a cheap $26 bikemaster one that works fine.

BTW, comparing anything with MotoGP is like oranges and unicycles. You want a decent backlit tire gauge with a hose? The motion pro ain't bad. It's $90 on Revzilla, so I would assume RD is even lower than that. Some people also think paying for expensive gear or motorcycles is crazy, to each their own i guess..
