Hi guys, I have a 2006 dyna super glide 1450, which has developed an intermittent stutter after around 15km or so of riding. I can accelerate out of it and it disappears for a while however returns.

sounds heat related maybe.  coil or ign pickup?

Good point, will investigate further 👍

How many ks on it mate?

It’s only done 27,000km

Right, it's not a lot, it had 02's you say, 06 dynas in Oz didn't have them from the factory, I know, I brought an 06 wide glide when they came out, so that tells me someone fitted them as the wiring was there just not the sensors, so it's been tuned to some degree as you have to flash a calibration with closed loop in it to make use of the 02's, you get anything with the bike?

It has a Dyna Fuelpack fitted under the seat, the bike has run great since I bought it in 2016.

Ok, sounds like it's not the tune side then, funny you should mention injectors, mine developed an intermittent stutter, not always there but sometimes mostly there, no codes, checked everything I could think of, I changed the fuel filter, you done that yet? Just on years it would probably be filthy, anyway I digress, turned out it was a broken wire in the injector harness right up near the plug, I had to pull on the wires to find it, years on cat trucks taught me that, you pull sort of gentle firm and if it keeps coming she broken, a pic of the culprit.

I changed the fuel filter when the petcock was leaking and renewed.

No wuckas, one more thing, the 06 came out with 8° injectors, they gave issues, the fix was the 25° injectors, same part number but the 25° number ends in 06A instead of 06, have a gander, maybe?

i used to have this similar issue on an 07 dyna,a little stutter [ just once ,then fine for many km's ],not temperature or time dependant,but was more likely when warm.fitted new injectors last may and apart from a broken lead to the rear injector a few weeks later,it has run fine ever since [ i believe the lead broke from poor alignment when i reconnected after repairs,interesting roadside repair in the dark ]

same as mine did Hilly...green wire as well.....coincedence i feel.i had a code come up for broken/loose lead to rear injector.

My experience of 2006 Dyna.

Where are you in Oz mate ?

Hi, I removed the tank this arvo, checked the wires into the connectors for the injectors and they were firm.

Forgot to mention I am in Adelaide SA

No worries. If you were in Perth WA or close I would have been able to help reflash the bike with O2 sensors connected and a correct calibration for 25 degree injectors.

You could do what Retro described yourself as well if you are so inclined, there are dollar's involved either way, buy a reprogrammed SE dongle, they are available, source a copy of the old Screamin Eagle Pro Super Tuner software, still doable, a laptop and cable, there are other options, one is a Maximus, it is current and supported in software and sales, I don't know what mapping options are available for the gizmo you currently have, anyway it would be good to hear how it all works out, even if you do take the solutions to PM.

This is the service bulletin. My 2006 Roadking had the 8 degree injectors . all bikes manufactured after January 2006 had 25 degrees from factory. Mine were changed under the service bulletin. Along with a new tune . I have the software and the dongle matched to my bike. Mine runs great with the harley map for 25 degree. Do you still have the original ecu?

Hi Mate,
