Exclamation Quickshifter working intermittently. Bike dies. DTC light always flashing. Help

For starters... My QS is working intermittently. When I shift from 3rd to 4th the bike dies like its out of fuel. Sit for a minute and it starts. Then it repeats itself. The DTC light will not turn off. It blinks but then never stops as I pull out. Any ideas?

Have you done any work on the bike recently, like rearsets, new tires, new levers, ? Trying to understand if there's more to the story. Right now it sounds like a trip to the dealer is in order.

Changed front wheel. The DTC light it working now but bike still dies when shifting into 4th. Came in... changed rear wheel. Same result.

I also replaced the shift assist yesterday with one from a 2013 because of the QS issues. I just disconnected it.

Sounds like you're getting somewhere. I'd check the clearance between the sensors and the ABS wheels or whatever they are called. If the gap is too large the DTC and the ABS will throw a fit. The quickshifter thing sounds like something is sticking or not returning as you shift. Damned hard to diagnose from this far away.

try taking a look at the main wiring harness to ECU plug. mine lacked the white locking tab from the factory. so it fit into the socket, but there was no lock to keep the contacts secured. this caused similar symptoms with stuttering and quick shifter intermittent working. took 4 trips to the dealer and a tow to figure that one out. bad plug from the plug manufacturer.

Also the ignition start switch on the right clip on is notorious for going out and causing the exact same problems, especially with the 2010 and 2011's.

Well... I unplugged the QS and the stalling stopped. It's at the dealer now.
