Default Help
Okay so about a month ago my bike started to develop a hiccup when taking off from a stop. It started to get worse so I thought I would do some maintenance. I changed the plugs, plug wires, ignition coil, front and rear O2 sensors, and twist grip sensor. It now does it less but still does it and continues to throw these codes. P1510, P2122, and P2138. I'm not sure what to do, I had it at the dealership and they can't get codes to come up and think a dyno tune would fix it. The bike is a 2011 Electra Glide with 67000 miles.

A dyno tune will not fix it. There is an issue with the throttle actuator or twist grip sensor. There was a service bulletin addressing corrosion of the electrical pins at the throttle body. That's where I would start.

I just upgraded the throttle body to a 58mm SE.

The problem addressed in the bulletin is with the wiring harness connector more so than the throttle body itself. Check for loose pins and corrosion in the connectors.
