Back for more tech help

So I am replacing the 16 year old tires on the bike today and man, that old rubber does not want to leave the rim.

Anyway, finally got the front tire off and encountered the TPMS, which is something totally new to me. My question is in regards to changing the valve stem. I want to put a 90° stem in for easier checking and airing when necessary.
Can I just take out enough slack in the hose clamp looking device as long as the TPMS doesn't get moved so I can remove the old stem and replace it?
If there is anything I need to be extra careful about, please pass it on to me.


Thanks in advance.

I am not sure what TPMS that bike might have. I doubt it was OEM. A photo might help.

100 per cent agree with this statement. This 1st pic shows the display unit.

I'm tempted to just remove the entire mess as I have never in my nearly 45 years of riding have needed such a luxury.

Assuming it still works that is about the best TPMS money could buy. But it has to be 10 years old by now and battery live in the wheel sensors is finite. I had that system on my R1150R and loved it, and the alarm function saved me a lot of grief on a couple of occasions.

As for the 90 degree stem extensions they can be an issue with rubber valve stems - causing too much flexing from centrifugal force.

But to your question, mark where the sensor is; loosen the clamp, change the stems, and retighten the clamp with the sensor back where it was.
