Rocket running poorly, suggestions welcomed

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:

I mean I get it...but I don’t get it.
To each his own, I got bigger things to worry about than what floats somebody else’s boat.
But this is their default setting, what they think about doing in their free time? lololololol Those are some sick puppies....
I don’t get it.
 
Glad you're back moving and made it in time!

Regarding 1 cylinder having bad plugs and the other 2 ok, ignore it for now. Get copper plugs in the bike and check again in 10k miles. Cylinder temps are not the same in our engines.

The important thing here is plugs...

Copper set costs $18.
Iridium set costs $60.

Just change your copper plugs every 10k and you're ahead financially and still reliable. For some that's every oil change, for others is every 2nd or 3rd change.

Not to hijack, but while we're on the subject, I'm puzzled that when I had my coil issue, one cylinder cutting out completely at times, missing like crazy, I had my mechanic change out my plugs while he was under the tank "supposedly" recrimping coil leads ( redid it myself, didn't appear anyone recrimped anything), he said my plugs, with 35,000 miles, looked ok, and showed them to me, the old ones. Would the engine burn off the soot every time it started running right again?
 
plugs with 35000 miles look ok ?:rolleyes: not fouled out does not mean they look ok
like your buddy has a blind date that looks ok:laugh::laugh:
my best guess would be that it could miss a few times and not look like it is fouled out.
 
Really. Iridium spark plugs in a Rocket? I change out my plugs every 20,000 miles with no issues. All burn the same. No issues even at 60,000 plus. Basic recommended plug nothing fancy. I do change my oil every 5,000 but realize that is not really necessary. Creature of habit i guess. May not be the smartest guy out there but i do ride a bit. For some reason can't remember the last time bike was trailered somewhere. Oh **** never been on a trailer. Guess i'm missing out on life. Tribal i can understand. He rides. Glad to hear you got it running.
 
I went to the shop and the tech said the two plugs that looked rich were the center cylinder. The fronts were so-so and the back ones were normal.

I forgot which Rocket website pushed the Iridiums for years and still does.

they put the standard NGKs in yesterday.

I almost bought the farm tonight.

I hit horrible blinding rain on Rt75. The radar showed it clearing but they lied.

I had to go 57 miles to meet an old friend at his club and should have bailed and gotten a room after it got dark and had trouble just seeing the road.

idiot me just put my high beam on and tucked safely behind a semi and followed his tail lights. We were in the slow lane doing 45mph.

Out of nowhere another semi passed me ON THE RIGHT doing at least 65 about one foot away. He never slowed down, went by, cut between me and the other truck and passed him.

Wow, I am still in disbelief. I checked and my taillight works but it was raining so bad he probably didn’t see it until he was about to run me over. Jerk!!
