Thank you for this information. You're right, no use hypothesizing if I haven't done the basic tests like checking for spark yet. Any and all information is valuable to me, as I'm brand new to this bike and not very experienced in small motors otherwise. Are spark plugs known to suddenly and catastrophically give out? The bike didn't sputter or choke up or otherwise show any signs of it's impending doom. It was working great one second and then completely gone the next second. I've experienced what happens to small motors when it's a mechanical issue, I've ran a couple sticks of hot glue through my 200cc 2-stroke Blaster engine, it ran like a champ for a couple weeks after but gradually died off. The issue with the KLR came on as sudden as possible and was very final. No amount of kicking was going to get that thing going again. It's something else.
