Hey all, I've got a 2013 street glide w/103. Supposedly cammed, pipes and tuned. Must have been a flash tune because original ecm is in the bike. I have a constant misfire in rear cyl. It's not steady but is always there. Idle, steady throttle, accel, pops and spits. Swapped plugs, known good coil and wires, no go. Compression test showed no sign of an issue, pulled the head anyway. Valves, rockers, gaskets all looked good. New gaskets on everything coming out. No codes, I'm leaning toward injector or ecm issue. I've read that tuners can be a problem but if it's a flash tune, would it be likely the ecm is at fault?
Missing out on some good riding weather because I cant figure this out. Anyone have any ideas? Hopefully I can provide enough information to point me in the right direction.
Any help is appreciated.
