I'm assuming when it turns over it starts. Does it? Hopefully you mean clicking noise because clunking noise could mean something way more serious. I don't think your bike has compression releases which do click at startup. If indeed it is a clicking noise get a stethoscope and try to locate the sound . Could be the starter solenoid.
Regardless, get your battery load tested before panic sets in. Even though it's new. Double check your battery connections and grounds. Loosen them , clean them, apply dielectric grease and reinstall.
You probably have an AGM battery. Make sure your using a smart charger if your going to leave it connected all the time.
AGM batteries benefit from regular charging, and while trickle charging can be used, it should be done with the right equipment to avoid damage. Always monitor the battery's state of charge to ensure optimal performance.

THE NOISE IS COMING FROM THE COMPUTER BOARD UNDER THE TANK DASH. ALL CABLES ARE CLEAN AND TIGHT.
BATTERY IS FULLY CHARGED. AND YES IT STARTS.

Post a picture of what you’re talking about. I’m assuming you talking about the Thunderheart ECM between the tanks? Sure wish I could hear it. Clunking noise…. Scratching my head on that one. Is this what you’re referring to?
