Stem pulled out

Anybody ever see anything like this before? I felt the back tire getting wobbly (going flat) so I headed home about 1.5 miles away, but had to stop about .5 from home because it was getting worse. Pulled the rear tire and this is what I found. Stem had pulled out of inner tube. I'm not sure if this was the original problem or happened when I drove on it the mile or so.

It's a DRZ400s with new tire Cont. TWC80 and a new tube both with less than 300 miles. My thoughts were:

1. Need rim lock(which I'm going to do)
2. Valve stem lock nut too tight
3. Valve stem lock nut too loose
4. Punctured tube and pulled stem loose drving on flat tire.

That's a match stick where the valve stem should be.

Did you check for a puncture? If you have a compressor and a blow gun attachment you can inflate it and check for a hole, or look at your tire to see if there is still something stuck in it. My guess is the tire slipped while it was flat.

It went flat then spun on the rim thus ripping the stem off. That's why there are rim locks on dirt bikes. Before you put a new tube in the tire check for what caused the puncture.

I had a stem pull out a couple/few weeks ago during a CDR ride. Clean tube, but with without the stem.
For whatever reason, I'd installed the tube a few days before inside a new tire without a nut on the inside. Bad on me.

I think this is what I did. I'm also going to install a rim lock.

Thanks for all the help, I knew I could count on this group.

If you can stand it, take the nut off or at least run it up the stem under the cap. Some have chamfered the hole on the rim to allow the stem to pull through or move around without yankin' it off the tube. Absolutly run a rim lock.
