I just installed FOBO tire pressure sensors on my 17 RGU. I have not ridden it yet but it does send the pressure to the app on my phone so I’m satisfied with that. They came with locknuts that you are supposed to install prior to installing the sensor and then tighten the nut against the sensor. I have aftermarket 90° metal valve stems. The lock-nuts kept the sensors from contacting the valve stem core, thus no reading. I removed the nuts and installed the sensors and everything set up fine. Has anyone else run into this problem? I know the lock nuts are furnished for a reason. I hope the sensors stay put.
