I have had cranking problems in the past but I think all my problems came from a bad (burnt) negative rectifier plug that @DEcosse found and fixed for me with a new harness. But the touring will give you fits on startup if battery isn’t up to snuff so that’s why I went to dual batteries, I have indeed doubled up or more on ground and power cables
Just my .02 cents , but I’d add a hd ground cable before you try cranking. Here’s why, the cranking is going to be harder now. The Ecu will see the voltage drop and shut the starter circuit down. At least it does on the Roadster. I ended up with an additional ground and the Toyota starter.

The weak link is the ground cable.....

I posted this to show you guys what's out there. I'm of the same mind as @1olbull. Usually carry an AntiGravity jump start battery whenever I travel any distance. Haven't needed it for the Rocket. Still running my original 2012 Yuasa battery. Plan to replace it this summer with a YTX20HL-BS battery from Yuasa again.

Those LI batteries are crazy expensive.

YTX20HL-BS is the same one I run - except, mine (regardless of brand) only last 2 to 3 years). :thumbsdown:
Because of this, I reckon not to experiment with a $400 battery!

I'll stick with my Duracell battery bought at battery's plus. Works. Have gone out with no common sense and rode off in temps of 10 degrees. No need for fancy stuff. Then again bike very seldom sits for long before i get the itch to ride. I get up in the morning and ride. Ex Marine so if it is raining and plan on going to work I do not ride. Got a thing about wet feet. Knowing it will rain on the ride home don't bother me much. Boy that is about a mouth full.

500 with that charger:D, some like the Walmart battery and just change it every couple years, for me it was about the 3lbs, I was running 2 batteries @ 26lbs, lean and mean, 23lbs in batteries, 38lbs in exhaust, some other poundages here and there and walla, fit and trim.
I took bags and mounts, hitch, windshield and passenger floorboards and rack off mine, 106 lbs, and no more high speed wobble to boot.
