I complained about the performance of the bike and the dealer told me that I had to just break it in. I had other persons ride it and told me that perhaps it was the throttle and or fuel injector. I called and complained again and they said that I needed to just ride it more and get use to it. I said it was losing power and maybe the injector was clogged. I took it to a local mechanic who then said that because it's under a warranty and the fuel injector is computerized that the bike should be looked at by the dealer. I called the dealer again and explained to the tech what I was told. He said we will make some adjustments and see what happens. He said I can have a trailer pick it up at my cost of $50 or so each way. Unfortunately, work got in the way and could not take it. The next season in 2017 I had the same issue expect this time it caused my accident. This propelling of fuel all at once to my bike almost killed me and injured me severely. The fuel gauge went on as I was rolling to a stop and continued through in first or second gear and then suddenly the bike bogged down and accelerated almost on it's with such intensity I lost control. Hit front and back break but back failed to engage enough to keep me straight ended up lifting back tire and flying over handle bars.

Fuel pump on the motorcycle is not in good working order when the fuel level emptys to a certain point in the tank not knowing when because their is also no gas odometer on the motorcycle the model begins to lag and leap at any time and as many times it wants to react as am twisting the throttle whether am switching gears or just in crusie it will do this cause me to lose control and may lose control at the wrong time like bad weather, up and go traffic, turning into streets, I have already took a fall on the motorcycle trying to making it inside the fuel island at a gas station and the timing when I was in my turn of a right going in the island it lag and leap at that time and took off on me causing me to fall and also the motorcycle I walked away unharmed just my motorcycle had road scratches going along the muffler and heat sheild and right side handle bar grip chipped..I took it to get service at the dealer for its first 1000 mile and while it was their they replace the fuel pump but it still does the same thing and only got worst. The next problem is the gear shift between 1st gear and 2nd gear most of the time is not completely in gear when switching between the two.

At about 70 miles on a full tank of gas, my xg750, when stopping and going it felt as though it had no power and then surged. This happened everytime I stopped and would go. The fuel light would flicker on and off but would go out once it stopped surging. I stopped and filled up the gas tank. Once full the surging stopped. After that I was afraid to ride over 50 miles without getting more gas. This past sunday I was just pulling out of my driveway when it occured again. I was just at 60 miles and was going to get gas. This time it surge while I was making a left turn. The surge caused the bike to jump and I started to lose control. I got the bike stopped but because of the angle of the bike it fell on its left side and I went down on my knee. The bike suffered what appeares to be minor damage. Bent clutch, scuffed handle and foot peg. The gear selector also bent and now will only start in neutral. This is definately a fuel delivery related problem based on the amount of gas in the tank. This could have been a lot worse if I was in traffic or even going at speed. Now I have a damaged bike and what I feel is not a safe bike to ride.

The motorcycle ,stalls from a stop and then accelerates very fast ,this happens when the bikes is low on fuel , but low fuel warning light is on. It is vey dangerous. It starts out from a dead stop ok , then stalls real fast , and after the stall it accelerates rapidly with no input from me the rider on the throttle control.

This is the second complaint as I have received no response from the federal safety agency on my first complaint # 10715309; and even though the dealer/manufacture attempted to repair the problem, the problem just happened again. As described by in in my first complaint and 53 other owners of this vehicle registering complaints - the vehicle has a dangerous throttle control issue due to a [known] faulty fuel pick-up tube/pump. As soon as the low fuel light comes on the motor will stall when the throttle is applied and then rapidly accelerate at a nearly uncontrollable rate. This happens when starting out from a stop, cruising down the road, passing another vehicle, turning a corner... This saturday 1 aug 2015 the problem happened while turning a corner with my wife on the back. The unexpected acceleration nearly through her off the back of the motorcycle and caused me to run off the road to keep from flipping/high-siding the bike.

I purchased my harley davidson xg750 on july 23rd and picked it up on july 24 with zero miles on the odometer. On sunday july 26 the fuel light came on with approximately 98 miles on the odometer. The next day july 27 while riding the xg750 it began to surge forward and stall while accelerating from a stop in first gear. It got progressively worse 2 more times when accelerating from a stop. I drove to a gas station and filled the tank up with shell 87 octane fuel. It took 1.819 gallons. Odometer reading was 102 miles. On july 30 with 166 miles on the odometer the fuel light came on while in route to work. After work on my way to a harley davidson service center. The gx750 began to stall and accelerate from a stop in first gear. I checked the fuel tank and it was almost full. The gx750 continued to stall and accelerate with out using the throttle. It started to progressively get worse and shut off at least 10 times. I was in heavy traffic and would stall in the middle of the intersections forcing cars to swerve around me. I made it to the harley service center with 206 miles on the odometer.

Upon reaching approximately 95-100 miles on a tank of gas I experience issues with fuel delivery and engine output. The motorcycle loses power and is non-responsive, then all of a sudden will shoot forward as it receives fuel again. This could cause loss of control or a multi-vehicle accident due to the unknown responsiveness. The problem gets progressively worse, and after about 10-15 miles of the symptoms the fuel light is then triggered. The issue does not happen when the gas tank is full, but only after using approximately 1.6 to 2.0 gallons of gas (or 95-100 miles of driving). I believe there is an issue with the fuel pump causing a loss of suction causing the bike to act erratically. I have spoke with many owners of the same bike and they have also had the same issue. Many have had their fuel pumps replaced but still experience the problem because of the faulty fuel pump design. I have set an appointment with my local dealer to have my bike repaired.

The bike surges when shifting gears, due to fuel pump not operating properly. It will start a lower speeds, then begin to happen at higher speeds. 2 fuel pumps have been put into the bike and the issue still happens.

While driving at a steady 35 MPH or so, the bike suddenly lost engine power (as if I closed the throttle) then without warning it opened right back up and lunged me forward as if I suddenly twisted the throttle open again. This has happened both times I got low on gas but before the gas light came on! There was still quite a bit of gas in the tank. And when I fill up, the problem disappears until I drive another 75 miles or so.

**this is my second complaint about this** the issue happened the first time at 86 miles on the motorcycle. It was fixed at about 500 miles. Now at 996 miles it's back. The issue happens when taking off from a stop. The motorcycle almost dies because it isn't getting fuel, then it gets fuel and lurches forward. There is still over a gallon of fuel in the tank and the low fuel light was not on at the time. I almost crashed and could have been hurt or killed by the traffic coming up behind me. The first time they replaced the fuel pump and I was told that it's a faulty design and the pickup comes off causing it to not pickup fuel properly. It appears the replacement came apart also. Is harley going to be pushed to redesign this before or after someone is hurt or killed?...updated 09/22/15 *bf updated 11/08/2017
