Starting issues HELP

Bought a 2012 Dyna fxdc about 3 weeks ago. Have a starting problem when I first hit the start button there's about a 2 second pause before it turns over and it's slow. It's almost to the point that I think it's not going to start. I've had the battery checked by 3 different people. They all load tested it all say the battery is OK. I've cleaned all battery connections and grounds. I rebuilt the starter solenoid which the old contacts looked good. I even unhooked the headlight to see if that would give the starter a little more boost. I find no error codes. I've had people on other forums say if it starts ride it and don't worry about it. Maybe I'm overreacting but I don't want for us to get out and get stranded. I out of ideas other than maybe a timing issue but acts like just can't get started on the compression stroke. Hope someone will have some other ideas. As far as I know it's stock. Thanks for any help and would be appreciated.

It does it every time you attempt to start it?

Start by checking the battery connections.
In particular the ground it it`s starting point.
Clean and tighten.

You could try replacing the Starter Relay it will be under the seat of under one of the side covers if there is another one in close proximity try switching them out and See if that Helps or the button on the right handle bar might be bad and need replacing check you wiring coming from the start button all the way to the Starter solenoid if possible a wire might be internally Broken and a moving point If you see one of the wires positive or negative swelled replace the wire it is corroded in between the Strands and won't let the power go to were it needs to

How was the battery tested with a actual load test or with a DMM Meter it makes a difference take to a auto parts they generally don't charge to test it

Relay should look something like this

Good luck let us know what you find

I have even purchased and installed one of those push buttons that attaches to the back of the starter solenoid that bypass all the wiring and directly engages the starter. Still same thing. Have cleaned all the battery connections and grounds, battery was checked on a regular battery load tester. 315 cold cranking amps.

If you have done all that it probably is the Starter then I have a remote starter button installed on my bike . I love having the back up . You might still have a solenoid issue or its the Starter a New solenoid isn't expense I bought a new one off Ebay for mine when I was having issues their not the easiest thing to change . Is there a ground running to the starter and has that been cleaned really well .

big john@do, the starter solenoid is like new after rebuild, the negative ground goes directly to the transmission gear case. I haven't tried moving it to one of the starter bolts, might be an idea.

I would not move it. But that`s just me.

You say the connections were cleaned. Did you remove and clean them. Or just on the outside surfaces?

In particular the ground on the trans case.
Two dissimilar metals with current passing through them and exposed to the elements.
A prime spot for electrolysis to happen.

Connections were taken apart cleaned and put a lite coat of grease added to connectors.

Earlier Dynas had two negative battery cables. Battery to a lug welded on left side of frame, then another cable from lug to starter (because of rubber mounted engine). My Dyna had symptoms like yours, and I found the lug was very rusty. I cleaned it and cable and starting was better. I now have a cable running directly from - battery to starter mounting bolt. I don't know if 2012 is like older models.

No matter what you call it, a turd still stinks.

Sometimes the cable gets corroded inside the lug and inside the copper strands too. That will cause the same problem. In that case new cables are the cure. If you see any black on the exposed copper strands its a good indication that you have interior corrosion.
