So the story begins with I have a 2013 Street Glide that I bought two years ago and never had a problem out of it until now. It all started when I went to Panama City Beach for bike week, I stopped and filled up with gas on the strip using the same pump my father used and all was well till the next morning I woke up to go riding and about 30min in the bike starting bucking and I could tell I had a misfire. We stopped to get some food and when pulling in the damn thing sounded like it was running off of one cylinder and I had a 20min ride back to the hotel in traffic. All the way back I was fighting with the bike cutting in and out really bad and once I got moving like 30-40 I could lay in the throttle hard and it would pull itself just fine but at a idle or slow steady speed back to bucking like a bronco. So I get back home from bike week thinking I got bad gas, I emptied the gas tank and mixed seafoam with 110 and 93 half and half and it seemed to help. I left the bike overnight at a buddy's house who rode it the next day and it started running better just a lil sputter or misfire every once and a while. So I rode it to bike night twice and to work three times and now my problem has showed back up again. I thought it was because of the EMITS but I have that disabled and I have never had it on, I have also changed the engine temp sensor with no luck. I'm lost guys I see so many post on here about a problem like mine but 90% never come back with the solution. The plugs, rocker box gaskets, and oil were changed two weeks before we left for bike week and it ran great. Does this sound like it could be my ignition coil or what other problems are people having with 2013 model 103's. Any help would be greatly appreciated guys!!!!!!!!!!!!!!!

 

I'd check for loose injector wire or plug wire rubbing against tank, Make sure the plug wires are clear. Wiggle the wires on the injects while idling. Also pull plug caps make sure they are clean and plug tops tight. You can try and dump codes. See if there are any.

 

 

Any exhaust leak on the rear cylinder? Exhaust tight at the head?
Is the O2 sensor tight in the rear exhaust?

Both of those will allow air into the exhaust leading to lean O2 sensor reading.
That will cause the rear cylinder to run rich. What does the rear plug look like?

 

Rear head pipe don't look very long. It wouldn't surprise me that the rear cylinder sensor reads lean.. How long have you had the pipes on the bike and how many miles. I would have expected that whomever tuned the bike disabled o2 sensing.

 

 

 

Was the 110 a leaded racing gasoline?

 

 

read up on how to reset your throttle. there is a sequence for turning the bike on and off, but i don't remember it exactly off the top of my head. it will reset the throttle position sensor so that the bike knows what is idle and what is not, i've heard of similar complaints as yours and this was what it actually was. some people shut the bike off with their hand still on the throttle, keeping it partially open, and some have it partially open at start up, this kinda whacks the ecm and throttle module out so it doesn't know where to start from.
also might remove and clean and grease the harness connector at the throttle module.
