Title: Leaking valve stem.
Post by: klaviator on April 27, 2017, 11:00:07 AM
My kymco's rear tire kept losing pressure.  I couldn't find any holes in the tire so I put some water around the valve stem and it made bubbles around the base of the valve stem.  Is there any way to fix that other than pulling off the tire and replacing the valve stem?

I assume it's tubeless.
You could just break the bead on one side and replace it . You might even be able to do it without removing the wheel from the scooter. But I have no idea how much room you have to work in.

It's tubeless.  I'll probably take the wheel to Midway Cycles and let them replace the Valve stem.  While I have replaced plenty of tube tires I have never tried messing with tubeless tires.

They are inserted from the inside.  So the bead has to be broken.  I do it with hand tools.

Second that motion....unless it's really stiff, low-profile tire.

Well I took off the wheel and took it to Midway Cycles.  They charged me a whopping $12.33 for parts, labor and tax to install a new valve stem :)
