Customer Question

Bike is 2013 Dyna Wideglide. When engine is WARM/HOT and idling, the rpms climb to almost 1400 and would go back to 1000 on their own after several seconds. Now when the idle picks up it stays up. Bie also coughs, sputters and tries to die when throttle is applied during times of increased rpms at idle. Also, now sometimes dies when rolling to a stop with clutch handle pulled in. Can be difficult to restart when it dies. Cold starts are still easy. Problems start when engine has warmed up. Have cleaned the IAC sensor and throttle body.

Level/amount of fuel in tank seems to not matter

When bie is running at speed say 35mph or more, does not exhibit any problems. Sometimes when changing gears and accelerating, there is a slight stall when applying throttle in each sequential higher gear.

Everything on engine is stock except muffler tips

the engine sensor that has the greatest affect due to changing engine temperature is the engine temperature sensor.when it begins to fail, symptoms such as yours are common.this can be checked by a dealership to see if the sensor reading is within desired and/or expected range after the engine warms up.check the wiring to ensure it's not grounding out or shorting to another circuit.if the wiring shows no problems, the sensor is the most likely cause. let me know if you need more help.Steve
