What is your current configuration and fuel map? Completely stock, or have you replaced mufflers or removed the SAI?
Tor map if it exists of the 2014 would be a first choice. But I think TTP does have a basic map that may help you out.
Have you had the throttle bodies balanced at a previous service?
Bike motor is completely stock. At the 600 mile service they balanced the throttle bodies. That helped the low speed fueling. But in hot weather it will still stumble.
I pulled the O2 sensors on my wife's 2012 Speedy and the problem went away. The SAI had already been removed as well. Using TuneECU I disabled the O2 sensor setting in the ECU.
No more stumble as the ECU goes from Closed Loop to Open Loop operatation.
