Thanks for the clarification, although in my experience the battery on my EFI has always had enough juice for the push start to work.. but I've only had to push start the EFI once, had to push start my carb'd many times back in the day though..

Just a bit of advice, colorado; when you post, try to use some punctuation. It can make it difficult to pull the situation, problem, and question out of a multi-line post when the poster doesn't use periods or commas. Not a flame, just advice.

If the jump vehicle was running, there's a good chance you've damaged the bike's voltage regulator. The little ~35 amp, shunt type regulators the Sporty uses, don't fair very well when hit with a 100+ amp charging system in the jump vehicle. https://www.hdforums.com/forum/9887690-post91.html

I have heard from a handful of sources that say you should ALWAYS use the kill switch rather than the key/ignition. Something about leaving fuel in the carb which will cause a weird fire up next time and also how it can trash your ignition with voltage or something. Obviously the Carb one doesn't apply to you, but the ignition crapping out may. Lots of discussion on this though.

It isn't as bad as you think. The batteries provide roughly the same voltage therefore it doesn't really play too big of a part in the regulators. Older vehicles without voltage regulators could cause some serious issues. Remember when we were kids and we would "rev" our vehicles to make the other vehicle charge faster? That doesn't apply any longer.

Then they should change the owners manuals of my 97-06-07 and 08 Ford vehicles where it says to raise the rpms of the jumping vehicle.
