2015 Harley-Davidson XG750 Engine Problems

“I experienced a lag and leap issue. I was riding my bike with about 83 miles on the tank of gas and out of nowhere it would pretend to stall and then take off. Would continually do this in the lower gears. Added a new tank of gas and it went away. Got to the same mileage and happened all over again. Harley replaced my fuel pump but it was very scary and I am worried it may happen again.”

“On my very first tank of gas the bike died at around 120 miles on the trip odometer while accelerating away from a stop light. It was a die and lurch that I have recently read others have experienced. I was changing gears from 1st to 2nd and the bike did a wheelie just high enough for my child to slide off the seat and onto the rear fender. I checked the gas and there was plenty to slosh around and no low fuel light. Filling up the tank stopped the problem. …”

“I purchased this vehicle less than a week ago, it also has less than 100 miles. The vehicle ran fine with no problems until it reached around 75-80 miles. At this point the vehicle would accelerate then decelerate and stall out after starting from a complete stop. This would happen in forward motion and also on turns. The problem occurred about 20(twenty) times leaving me (vehicle stalled out) in the middle of intersections and also in city traffic. The problem occurred in 1st, 2nd, and 3rd gear. …”

“While accelerating from a stoplight, the motorcycle engine lagged, surged, and then stalled completely. The motorcycle would not restart while straight and level. I was able to coast through a right turn to down a small decline where I was able to start the engine and carefully proceed to a nearby gas station (<1/4 mi.). The trip indicator showed ~144mi. The fuel tank took 2.87gal to fill. The stated capacity of the stock fuel tank is 3.5gal, leaving ~0.6gal in the tank at the time of incident or ~20mi worth of fuel before empty. …”

“This vehicle will hesitate when accelerating from a full stop and then feel as if it is about to stall then surge. The pattern may repeat several times over several seconds before there is consistent full power. It happenes when there is about 85-90 miles driven on a full tank. I was almost rear-ended several times recently since the driver behind me reasonably expected that I would be able to maintain acceleration away from the stop. Furthermore, it is nearly impossible to maintain control of a turn from a stop when the bike is hesitating and surging throughout the turn. …”
