Fury won’t crank or start

Sounds like the new battery is flat and needs charging. If you have a jump starter try using that and see if the bike starts, if you don't have a jump starter use some jumper leads and jump start the bike using your car battery. If the bike starts there is something wrong with the new battery, if not check the battery connections and all the fuses to see if any have blown.

Thanks for the info, new battery was completely dead, on a slow charge now and I’ll let it charge for. While. I sure hope it’s nothing major. It was running great until I tried to install a cobra tuner.

This is new-battery-normal. From my experience, they most often need topped off before installation, and it is just a good rule of thumb to do it as a matter of course. Charging a low battery works the vehicle electrical system harder than maintaining a full battery.

That said, if it was completely discharged that might give me a moment of pause.

I was going to suggest the starter Solenoid but that’s if the battery was good. The one on my VTX did it once without warning
