Jump Starting
I did a search, and learned that you attach to the starter. Which I did not know.
But, I have a different question.
Some of us have small jumper packs. Some brands, include a cigarette lighter male plug. With the idea, that you can jump start a car using the plug.
Although you probably have to let it sit on there for awhile.
So, my question. Is it possible to let this same type of jump pack, (after making an adapter) plug in thru the trickle charger pig tail ?

Don't ever jump start a Harley except in an emergency. And make sure battery is OK before you do it. If by chance battery is bad and you do jump start it, your Harley charging a bad or shorted $120-$200 battery just may take out a $1000 alternator and regulator by the time you replace it all in parts and service.
And absolutely do not try to jump through a number 10 wire with a 12 AMP fuse for a starter that take 100+ AMPS. And PS if you have not heard enough, that pigtail is backwards if you plug the plug with the alligator clips that came with the charger to the eye leads that are attached to the battery plug that normally plugs into the charger.

Yup, best to avoid "jump" starting an HD.
Hard to "bump" start the FI bikes too, unless the battery has enuf to energize the fuel pump/injection unit.
Otherwise, it's go to costco.com for "new battery" time!

Too cool. I did not know they had them. But sure enough. Highest one is 119...lowest is 47. Interstate brand

The answer to your question is no, it is not ok to jump start your bike using the pigtail harness for a battery tender.
If you try it, those little wires will tell you why...

I've jump started lots of things over the years. You can argue it is a strain on the stator, chraging a dead battery. But I have my doubt doing it once, will wear out the stator. It is built to charge. Also a low battery is differant than a battery that is shot. You should be able to tell the difference
Speaking from my bowels, I'd rather jump start a battery, than load test it. I don't like stressing batteries
I've never seen a jump pack for the cig lighter. Do the instructions address it? Though as you said it could take awhile. Putting it on 2 amp or 6 amp for awhile, might work. I've used 6 amp for a short time on my 4 wheeler, and had it started. Doing it when battery was low, but not dead, clicking or turning over low.
I could see building one with a a low setting that you left on for 10 minutes. But this would be for a battery that was just a little low.
Ive started many vehicles with a battery charger, on 6 or 10 amp setting, for a few minutes. Actually done this more than jump starting. Do it to my tractor, atv, and mower. I don't jump start as much, cause easier to just one an extension cord and wait 5-10 minutes. I the charge on while trying to start.

when it comes to jump start, it is all about voltage and lesser amps.
when a battery fails, usually the cells cannot produce the voltage but still have ampacity although reduce. the reason a start is slow and dragged out. the jump pack through the lighter is supposedly enough to raise the voltage on the battery but that can be very iffy, the direct to battery can add some ampacity as the battery used is capable of short burst. not all jump packs are equal.
a shorted battery is a lost cause and would not charge anyways.
the pmg is NOT field forced and produces a finite charge capability. the machine actually runs off the regulator with the battery providing short fall. the machine will run without a battery, used to do that on the track on a honda.

At lower RPMs you may not have enough capacity in the stator/alternator. On my 01 and 07, I can watch the current change direction when I rev up the motor. AC votlage output increases with RPM. With fuel pump and other electronics in modern vehicles it may not have enough capacity.
I do know, from forgetting to plug the stator back in, you can run for a long time, and have many starts, off just the battery, with a carbed bike

should be fine using a booster pack directly to starter or battery terminals.... little more dicey from another vehicle... avoid that if possible... some harley shops have you tube videos on this.... check them out
