I discovered my rear tire was just about flat, with a nail sticking out of it. I tried adding air with my onboard compressor, but I could hear air hissing out around the nail, so I knew I couldn't tackle 300 km of mountain roads & passes without fixing it. Of course, the nearest town with a motorcycle shop was over 100 km away and, being a Sunday, was closed anyway.
I figured the only thing I could do was to try the emergency tire plug repair kit I've been carrying for years (the kind with a T-handled plug insertion tool, rectangular strips of rubber, and a tiny tube of glue). After pulling out the nail & letting the last of the air out, on the first attempt at inserting a plug, 1) the new, sealed tube of glue contained only air & one drop of glue, and 2) trying to push the plug in resulted in the entire end of the tool breaking off in the hole in the tire.

One of the other guys had a kit, too, although his used knobby cylindrical worms of some kind of rubberized orange putty instead of strips of rubber. It also included a reamer to open up the hole in the tire. No glue, or anything. We were finally successful in getting one of those plugs into the hole & extracting the tool (we did spread the end of it enough that I need to replace it for him), leaving about 1/2" sticking out. I trimmed off most of it, pressurized the tire, and checked for leaks with soapy water. It seemed to be holding properly, so we did the ride home without issues (speeds up to 120 km/h).
The instructions in his kit say to ride the bike, very slowly, directly to a tire repair place which, of course, was impossible. At this point, the repair is still holding fine, but I will have to effect some kind of permanent fix or replacement of the tire (figures - it still has 80% left, and I can't get a tire locally in less than a few weeks - by which time riding season will have ended).
Anyway, has anyone here had experience with using these kits? Any recommendations for a particularly good one? I know I won't be going on any long rides without one in the future, but I want to get a decent set.
Or...other ideas for emergency flat repairs (something small enough to tuck away in a corner of a saddlebag, etc.)?
