Valve stem leaking. Went down to the local service station to pump a bit of air in and the air was leaking from the stem core. Run flat got me home. I have a spare valve stem so my next move is to get a stem removal tool and change it out.

Coldwing, did you hit it with a shot of air a couple of times? Might be a dynabead blocking the core and not letting it close and seal.

I would pull the valve core and check it first!

valve stems

Advance or AutoZone sell both pkgs of cores and the removal tool. Don't leave home without both of them on board.

Follow up fellows. I caged it down to Advanced Auto and bought a $2.00 valve core tool. I gave the core a few tightening turns and I can't swear to it ..........but it " felt " like something settled in as the valve pin popped out and stopped the flow of escaping air. It was actually only down to 28 psi by the time I got it in my driveway. Could not count that as running on flat! Oh well. Since the pressure was stabilized I rode up to my Goodyear Dealer and we checked the torque on the valve stem core with a professional tool set at 4 in. lbs torque and filled it to 36 psi. at a warm tire temp. After four hours of sitting still the psi. was holding at 34.5. Was it a Dyna bead or a valve core issue ? One never knows do one. :shrug: Thanks Richard for being there when I called.

I discovered one thing: My $9 digital tire pressure gauge from Pep Boys is not to be relied on. I have been getting psi reading from 30 to 34 for the last couple of days as I have been monitoring the pressure as the bike has sat on the center stand. I took it over to Don's house today with the intent of changing out the stem core. I left my house with a reading of 30.5 psi., drove a mile to his house, used two different gauges of his and got readings about 36 psi. That's the pressure I had it filled at the Goodyear Station on Sunday. That settles that. Goodbye pressure gauge.

I thought about that Murgie. I'm getting an AccuTire gauge tomorrow to put this discrepancy to rest either way. Love the tire though.Best thing I put on the Wing besides the grip puppies.

I thought car tires WERE grip puppies.
