For **** and giggles when you have a helper put it in second or third gear and get it rolling with the clutch in then drop the clutch to see if the engine will turn.
Did some work on my bike and no start now …

Well I have the charger on it for over night and it set at 2amps/hr
Don’t think I’ll have any luck with it as such but we will see, I’ll try to get a video of it when it hooked up to the car as well or I can and post it
Relax

If the bike can't even crank over with a car battery boosting it, then something is wrong. Unless your car battery is also weak, but that would be a bad coincidence.
Firstly, the bike battery dropping to 6v is an indication it's either gone bad or you have some engine problem like high compression or seizure that the starter motor is struggling to overcome.
I've seen cases where the vehicle can't be boosted while the bad battery is still connected because it prevents the full current from reaching the starter. If you disconnect the bike battery and attach the jumper cables directly to the bike's battery leads, the bike should start. and you know the issue was the bad battery. If the same thing that you describe happens where the car battery is also struggling to crank the engine, then you have some type of engine problem. Pull the spark plugs out and see if anything changes - that prevents any conpression from building up and the motor should crank freely.
Another issue could be your starter motor is dying, but you didn't say you have a Ducati or Aprilia...

I assume it’s an xv1100. Check the positive and the ground on the starter - the starter ground can be a gremlin on 750 and up Viragos.
As a quick check, attach a jumper cable between the starter case and your bikes battery ground. If it cranks better, remove it and clean up the starter case on areas where it bolts to the engine.

OP says it's a 2001, so not a Virago. Most likely a V-Star.
Don't hook up the battery charger to this setup.
Just attach the jump start cables between the car battery and the motorcycle battery, try starting the bike and video the results.
Need to understand why the car battery isn't starting your bike, so audio and video might give more clues.

Ya I just tried starting the bike after being on a slow charge for the light and nothing.
So then I disconnected the bike battery and put the jumpers from the car right on the bikes leads and still nothing.
Then I tried to put a wire from battery ground to the starter like suggested and nothing
When I say nothing I mean all it does is click once under the seat - assuming it’s starter relay

Take the positive lead from the booster right to the starter and see how it cranks.

Just tried that and nothing different just a click under the seat
Is there a way to bypass the starter solenoid? I wonder if it is bad …
If it is, this might have been a self-inflicted issue. You said that it did crank yesterday:
Now it just clicks? Sounds like something in the starter system got blown. Perhaps when you introduced a battery charger to the mix, especially a float/intelligent one like the Nautilus which tests the voltage and tries to compensate by varying the amperage output.

Yes it did crank yesterday a couple times before it would click
That does bypass the solenoid if you went right to the starter with the positive booster cable , nothing under the seat should click.

Battery test with multimeter at 12.86 resting and off, once you turn the key the loads pulls it down to 6-8.
But if it was battery the bike should have started once the battery leads were hooked up the car battery correct ?

Oh boy. I think you should have clarified that he needs to attach it to the nut on the starter. Hopefully that clicking sound isn't arcing if he touched the body.

Yes it was attached to the nut/wired connection there
When you say you turn the key, you don't mean pushing the starter button, correct?
So just turning on the headlight and dash lights pull your battery from 12.86 to 6-8?
Sounds like multiple issues. Your battery is definitely toast, but your starter system is also fried.

So when the bike is off it’s 12.86 and then when turning the key it slowly trickles down as the dash and headlight is on. When hit the start button that’s when it goes down to 6-8
You need to be more specific. The above is very different from this:

When i say load i meant that when you hit start button
OP can help by providing more info, as per below link.
