So, I went riding Saturday, noticed before I left the rear looked and felt low, about 7 lbs down. Hmm, not good. inspected carefully, nothing,
Aired up, got ready, took an hour, and the tire checked out ok.
High speed run to off road area, down about 4 lbs. Hmm again.
3 hours off road, average speeds around 20 - 30 mph. tire at pressure, no problem.
High speed run home, felt funny halfway, down about 9 lbs. Ok, this is weird.
Aired up, got home, down about 5 lbs. Aired up at home, next morn, pressure ok. Weird again.
At work, (high speed run to work) down again. Now I'm perplexed.
Got home, removed wheel, tire and tube, inspected inside of tire, nothing. Aired up tube, no leaks heard. overinflated tube, put in tub of water, rotating to find leak. NOTHING!!!!
I inspected and tested everything, including valve, nothing.
I spent 45 minutes looking for a slow leak, absolutely nothing. I have had MANY flats in my career in riding, this ain't my first rodeo, and have never encountered this.
This morn the tube was just as full as last night, as though there is no leak.
Is it possible that the valve stem spring is weak, and allowing centrifugal force to depress it and cause this issue?? because I cannot explain this one.
New tube today, but **** if I am not frustrated at what SHOULD be a simple issue.
One cool & froody dude who knows where his towel is!
