My KLR has been running like new and killing its quota of mosquitos every day on the way to work and everywhere else. But I didn't ride it, and left it in my hot garage from Sunday until today, Thursday. This morning it wouldn't start. Tonight, when I got home, it still wouldn't start. Strong battery, turning over fine, kill switch on, half tank of fuel. Just wouldn't hit. Then it started for a couple of seconds and died. Tried some more. After a bit, it started right up and has run fine ever since. What the heck? Vapor lock somehow due to our super-hot temps of late?
