I know my Valve on my rear tire has been leaking and I have a new one on the way....but I had way less in it than should be when I last checked.... so a quick check with detergent & water had the leak found....Nail. So out with the Stop & go repair kit (I have used it on the car and a year later both leaks are holding)
A few pics

tire cleaned where the bubbles were and hey presto a nail is visible

Stop & go puncture repair kit. Drill to ream the hole, sharp tool to push in the sleeve guide, and tool to wind in the plug, blade to trim the excess....after you pump up the tire

Guide with handle removed

tool to push the bung in installed (bung pushed up in it completely clear of the thread)

Tool removed (backing out the thread first)

Bung trimmed after pumping it up first!

Spray with soapy water again to check for leaks..... no leaks, good to go until I change my valve and I will do a better patch
