Won't start, at my wits end.
Alright, Sunday I rode the KLR.
Monday, I was planning on riding her to work. She started up and while I was suiting up, she just died. Sounded like somebody turned the key off. Figured I was out of fuel (later found out I'm not), so switch to reserve and thumb the starter again. Lots of spinning not much actual running. It will catch a time or two, turn over on it's own power for a revolution or two, then die.
I've checked the spark plug, it looked good, but I replaced it with a new one anyway. Checked spark while I had it out, looked like a nice clean blue spark. Tried starting with new plug, fired up, ran for maybe 5 seconds, then died.
Sprayed carb cleaner down the throat of the carb while trying to start, got nothing.
Checked valve clearances, one intake is towards the tight end, but still well within spec, all other valves are dead square in the middle of spec. Checked cam timing while I was in there, looked to be spot on, Cam chain still plenty tight.
Pulled carb apart, went over everything, pulled main and pilot jets, both sparkling clean, as was everything else on the top and the bottom of the carb. Float bowl is filling as it should.
Bypassed all safety switches, nothing.
Charged battery fully.
Turns over like a champ, just doesn't fire. Might get a cough or two and it try to fire for a revolution or two, but never an idle.
I have only two ideas left for what it could be... KACR failed engaged, keeping it from getting full compression. Or bad coil. Anybody have any other ideas before I order a $100 coil? So tired, just want my bike to run!
Oh, other notes incase they may be relevant...
Just started using oil in the last couple weeks.
While on the trail slowly crawling my way out of a rock hole the weekend before last, it was doing some dying. Idle steady, then died, but restarted like it was nothing. Did that a few times.
While it was running immediately prior to not running, it was making NO unusual noises, sounds, or vibrations. It was running just perfectly, no hints at all that I would have the strong urge to take her out back and put her down like a lame horse.
