Like an idiot I left the key in and on...came back and she showed no signs of life. I have tried jumping it, the electrical works but no reaction from the ignition. I tried a bump start with two in back pushing while popping clutch in 3rd gear, no luck (got close though). Any thoughts short of towing it to the dealership? I'm might try another bump start while being pulled by rope behind a car... seems like too much hastle tho...

I would not do the rope method! I watched videos of that method failing and the guys bike got trashed! Short answer, purchase a trickle charger and charge it or purchase a new battery.

I'm surprised the bike didn't fire up when you were being pushed. Try it in 2nd gear instead or 3rd

I am not sure but I don't think you can bump start them because of the PGM FI, (can't do it with other FI Hondas ) put a trickle charger on it or (the best thing to do ) take the battery to a dealer and have them recharge it the gel battery needs a deep charge to really charge it back up, takes an hour to do it on a fast charge or 10 hours on slow.

thanks for advice. i just got her going tho! i unplugged and replugged the engine stop relay which seemed to get the ignition to work on my next jump attempt. just in time too...any more than 24 hours without a ride and a little piece of me dies...

I would still get it on a charger/tender, just riding it will not charge it very well from dead like that

I'm sure you cant push start a bike with fuel injection as there is no fuel delivery until the motor starts-thus the buzzing noise when the key is turned on.no power-no fuel

Electronic ignition with an electric fuel pump doesn't lend itself to catching the bike in gear like the old style carbueated bikes.

Not completly true... If the battery has enough power to run the lights, you can bump start it. The battery in my VFR died once to the point that it wouldn't turn over the engine, but had enough power to boot the ecu and presurize the FI, and I was able to bump start it rolling down a slight grade.

Put it on a battery tender. They are about $45 and work very well. I keep mine plugged in and never have a problem.

The above is very true. Battery tenders sure do extend the life of your battery. Good for very cold winter months when the bike sits idle for long periods of time.

I bumped started it yesterday! It worked! I left the lights on and after two hrs, the lights worked, but not enough juice to start. I tried several different methods, but nothing worked. I had my wife pickup my trickle charger. The only one I have, and I plugged it into the cars power inverter and still after two hours, not enough juice to start it.
I couldn't leave it, so I started pushing again and vroom....second gear did it! I had enough power to get fuel into the injectors when I turned the key, so the bump start was perfect.
I learned that you can still bumpstart, if you have enough juice to make that buzzing noise when you first turn the key, before you start it. It is putting fuel into the injectors.

Pick a different color buddy, that’s my blue. I’ve been letting it slide. All the other colors are still up for grabs, except the Pink. WildBill likes to post in Pink occasionally.

SECUREST;

Sounds like it's time for a new battery! Leaving it sit in a discharged state for too long will cause it to sulphate and it will no longer hold an adequate charge.

Be careful with the jump-start routines; you could end up inadvertently frying a diode and/or a regulator.

Cheers
