IMFUO, someone "screwed", OR would that be "UNscrewed", with ya.

I've broken stems off (mud trucks and tractors) and had 'em come loose, but never just "blow out" like yours.

an o ring gasket in a cap got dislocated on me once and held the valve core open enough for the tire to leak slowly. there aren't many threads on the valve core itself so if it's not tight it "might" blow out. i have seen threads in the stem be damaged and not be able to tighten the core.

Legend has it Evil Road Spirits have been latching themselves on to motorcycles for as long as there have been bikes on the road.

I would think the schrader valve would begin leaking when it is less than one turn from being tight. For you to experience the leak over 500 miles and at least a day since the last time you checked the tire is kind off extra ordinary. You may have forgotten to replace the cap when you checked the air. If you had slightly loosened the valve when checking the air pressure, it could have been doing a slow leak during your ride. For the valve to fall completely out is a bit troubling though.

When I installed a new schrader valve it screwed right in no problem and seemed to tighten down right.

I agree with you on the slow leak if it wasn't tightened but the valve was installed back in August and never leaked. I'm pretty sure I had the cap on but anythings possible. I had a chase car behind me when the tire went flat and the guy driving it told me the tire went flat so rapidly he thought I hit something in the road. I believe the tire was completely aired up when the schrader blew out I just dont know what caused it

Not sure how someone could of pulled the valve, aired it up and replaced the cap without losing all the air again....doesnt seem likely.

That's a possibility considering it was Halloween

They couldn't pull the valve without losing air, if someone messed with it they probably just loosened the valve enough that it eventually failed. I don't know if that's what happened or if the valve stem was just defective but that's why I posted here to find out if anyone else had a similar experience. So far noone here has had anything similar happen and the general consensus is the valve was tampered with. I tend to agree with the consnesus but I'll never know for sure.
