I've just experienced this with my 2014 non-ES.
I purchased this bike from an owner in Texas at the end of September, with 7900 miles on it...........It now has 9200 miles on it.
Since September, and any time I've taken it out, I've never had a problem starting the bike normally.
I always use the kill-switch to shut the engine down, then turn the bike electrics off with the key (always habit for me, and good practice to do so)
To start the bike I always turn the key on, wait for the gauges to come on, then start the engine with the kill-switch. I never touch the throttle while cranking the engine.
There have been a few occasions where the bike sat for a few weeks, or even a month without starting it. Never had a problem.
I've rode it to work a couple times when the morning temps have been in the high-30s. Never had a problem.
I think there have been a few instances of me releasing the start switch prematurely before the engine caught. Always fired right up when I made a second attempt.
I have even started a cold engine, let it run for 20-30 seconds, then shut it off. Always started right up the next time with no issue.
The last time I had the bike out was last Saturday. Took my son Logan out for a ride. Got fuel close to the house, then rode for about an hour and a half, then stopped for lunch. Just as we were about to leave, a couple guys in a pickup truck were admiring the bike. They asked me a bunch of questions about it, and said one of them was interested in getting one. He asked me if I would start it up for him so he could hear it, so I did. Revved it a couple times, and then shut it off. They left, and we hopped on the bike and fired it right up, and headed for home. (about 45-minute ride)
Fast-forward to yesterday....................It was a relatively nice day, with temps in the mid-50s. I drove my Jeep home on my lunch-break with the intention of riding the Super-Ten back to work, and then going for a ride after work............I get home, back the bike out of the garage, put all my gear on, close the garage door and attempt to start the bike.......
Use my normal starting procedure, and it just cranks and cranks and cranks.............I turned the switch off, the key off, and wait a minute.
Attempt number two...........Same result.
Next attempt I do the same procedure except hold the throttle wide-open...............This time it popped a couple times but never fired over. Still just cranks and cranks.
I tried different combinations of this for about 10 minutes, until the battery was starting to not want to turn the engine over very fast anymore, and the gauge cluster was turning off and on.
I pushed the bike back into the garage, plugged in my battery maintainer, and drove my dejected self back to work in the Jeep.
A few hours later, after arriving home from my work-day, I unplugged the battery maintainer and tried again......................No luck! Same result.
Plugged the maintainer back in and left it for a full day, until today.
Got home from work and unplugged the maintainer (it was reading that the battery was fully charged)
I took the side cover off so I could measure battery voltage. Was reading 12.8 volts before I started.
I first tried to crank the engine without touching the throttle. I cranked it for about 3-4 seconds while watching the voltmeter. The bike did not fire up, and the voltage was around 10.8 while cranking.............Battery is still good.
Next I tried holding the throttle WFO, and after about 3 seconds of cranking it roared to life! Belched a ton of black smoke out of the exhaust!
Was definitely flooded..................
I let it run until the fan came on............twice. Revved it a bunch of times, and it sounds healthy and normal.
Voltage at idle is around 14.10 with no accessories on, and 14.04 with the heated grips on High.
When the cooling fan comes on, the charging voltage at idle is around 13.8...................Charging system functioning perfectly.
I ran it until the fan came on again and immediately hit the kill-switch. (the fan runs for a long time because you are no longer circulating coolant) Battery voltage stabilizes around 11.6 with the engine off, and the fan and lights still on. I let it sit like this for around a minute, then hit the start button with everything still on. It cranks and fires right up with no issue!
I'm going to chalk this up to a rare (hopefully very rare) instance of the dreaded "Cold Flooding" no-start issue that many people seem to be having. It is definitely not just limited to the "Gen-1" bikes.
I have a new battery on my radar, but there doesn't seem to be anything wrong with this one? As far as I can tell, it is the original one that came with the bike (Yuasa YTZ12S) so its 5 years old now..................Not much more life could be expected from it I suppose.
