I was scratching my head to figure out how you guessed the repair cost so closely. DOH, then I zoomed into the photo of the plugs. I didn’t know my bill was in it.
I’m running Power-Tripp Jardine 3xK&NRU-2780a in that bike. It ran fine and I never got it tweaked as no one in my area knows how to tune a Rocket.
As mentioned, I did switch out the 2780’s for the RC-3680’s last month. I didn’t notice anything except more sweet engine racket.
I do think two of the coil wires were loose AND the battery wires were an issue.
It ran good the short distance before the plugs were replaced but maybe the hesitation would have come back.
I was actually very lucky the two plug sockets DID NOT work. If one had, I probably would have pulled two easy-to-get plugs and chances are they would not have been the oil rich black ones.
At that point I would not have replaced them and went down other dead ends or gotten frustrated and had the dealer in Pompano send a truck.
That means I wouldn’t have made Key West for my birthday sunset and taken these freaky pictures for all y’all:
