2015 Harley-Davidson XG500 Vehicle speed control Problems

“Motorcycle will bog down and then surge without warning if there is about 1/3 of a tank left. Low fuel indicator never comes on before it happens and it's worse when driving on hills or while banking in turns. Last night was the third time this has happened to me as I was coming up the hill and turning in to my driveway the motorcycle bogged down, and before I could completely roll off the throttle it accelerated and pushed the rear wheel out causing me to lay my bike down.”

“July 3, 2015 - it stalled twice while sitting completely stopped at stop signs with the clutch fully pulled in. It idled low and then completely died. Restarting the bike, I was able to get it moving with quite a bit of leaping and lagging and the engine sputtering. Once up and through 1st and 2nd gear (sputtering like if was missing fuel) it seemed to suddenly engage and was ok. I compensated for the lagging, but it kept jumping as if suddenly catching without pressure on the throttle increasing. …”

“First accident was at a traffic light intersection, with low fuel, but no fuel light yet. Accelerating on slight uphill left turn, from stop at light. Went from 1st to 2nd, was leaving the curve when I hit a pot hole. The bike lagged slightly, then accelerated suddenly I was unable to avoid hitting the curb and crashed. Being a new rider I assumed that the pot hole had caused me to roll on the throttle, which is very responsive, and put this incident down to rider error. It was a sanctioned club ride, so reports were filed with the dealership. …”

“Vehicle lurches forward uncontrollably. Throttle response is extremely erratic. This caused inexperienced rider to lose control at a low speed and was thrown from vehicle as it went out of control onto the sidewalk. Fuel tank was nearly full. Continued riding exhibited extremely erratic throttle control. Vehicle is very unpredictable.”

“Like many others, since day 1 my harley street 500 has been experiencing a lag and leap issue. The first day I had my bike I experienced an issue where when starting from a stop, or making a turn at low speeds, the bike would stall like it was out of gas, and then suddenly accelerate again, almost throwing me off the back of the bike. I brought my bike to the dealer, they told me I was low on gas, filled me up and sent me along my way. …”
