Putting miles on my new test bikes lately (when repair jobs & weather permit) and one quit on me today. Was pulling up a hill fairly aggressively when it started missing a bit & loosing power, then quit about 100 feet farther up the hill. Looked it over well, saw nothing, checked wiring, unplugged kill wires. Pushed it to top of hill and came down, and it started again. Ran a bit crappy with intermittent missing back to shop. Drained carb into glass jar to look for water as I had added fuel before starting out, but didn't see anything - checked all and reconnected wires. Rode around for a couple miles with no problems. Now, if I never figure out what happened, will I trust it on a long ride? Troubleshooting after the fact just kills me.
