2015 Harley-Davidson XG750: wrong fuel gauge reading

Filed Mar 15, 2019 · Brakes, Fuel system · 124 miles · PA · crash · 1 injury

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.

The motorcycle's engine keeps loosing power then regaining it suddenly when accelerating from a stop in 1st and 2nd gear, especially going uphill. This seems to be related to the fuel level as around that time the fuel light was lighting up intermittently.

Ok so first time I had an issue was in january when I noticed a major surge to the point of stalling out reguardless of fuel level in the tank. Took it to harley once and they could not replecate the issue. Second time within the same month same issue the fixed it by replacing the fuel pump stating it was faulty. Had no problems for months till recently in may I started noticing I was on the highway when my fuel was low and the light came on I pulled of at an exit to get gas and it started to surge again like it did before. Tank was almost empty so I filled her up. No problems the rest of the day. Next month of june I notice my light started coming on when I was leaving my work and when in first or second gear it surges really quick from power to no power to quick power all of a sudden. So I went and filled up the tank and yet again no problems. Seems to be happening around 100 miles per tank. And when at half tank taking right hand turns it looses power too. Very easily could through an inexperinced rider off if they dont know how to maintain throttle and clutch control. Also noticed she has issues with starting in the morning when cold if the bike sits out in the lot, have to give her gas to warm up. Liqued cooled and fuel injected motors should not have that issue especially with only 2000 miles on the motor bike is not safe at this time probably due to the amount of foreign parts on an american machine.

If the vehicle's fuel tank level is approx. Half or lower, the vehicle may abruptly stall and surge forward. The lower the fuel level is, the more often and abruptly the stall and surge is, and can happen during normal driving conditions, especially up an incline. This happens before the low fuel indicator illuminates. This behaviour can easily cause an accident or fatality.

This is the same issue as found in investigation pe15015. This is the first time I have experienced engine stumble (stall), commonly referred to as lag and leap. This occurred when I had a low fuel level in my tank, (tank was filled 10 miles later with 3.1 gallons into a 3.5 gallon tank). When accelerating from a stop into a right hand turn I experienced a near-stalling of my engine. I did not adjust throttle and very quickly after that stall a surge in engine RPM occurred with brisk acceleration, followed by another near-stalling and another surge. A third less noticeable episode occurred after that. I did not adjust throttle position throughout the episode. The timespan over which this took place was probably 2-3 seconds. I am familiar with the complaints which have been around this issue and so was confident that I would be able to get through the episode without losing control of the bike. Several minutes later and after another stop with very slow acceleration from it, during which the stall and surge did not occur, I decided to test whether it would happen in 2nd gear on a straight trajectory. At about 20 MPH I accelerated in 2nd gear and again 3 cycles of stall and surge or lag-and-leap did occur, with the 2nd one being most noticeable and the third being very minimal. I was happy I was able to make a left turn across two lanes of road to get into the gas station, without it occurring again. I drove another 40 miles after filling my gas tank without it happening again. I had previously filled my tank with 3.4 gallons during a ride when my motorcycle had 1000 miles on it, without this phenomenon occurring.

Starting with a full tank of gas I drove for approximately 100 miles and the bike began to surge and buck. Problem getting worse the more I drove. After 20 miles the low fuel light came on . I filled tank with fuel and the problem went away until I again drove approximately 100 miles. Bucking surging began again and got continually worse until the low fuel light came on 20 miles later. Filled with gas and problem cleared up. Dealer has had bike three times to repair. This last time I told them the fuel pump is losing suction possibly because of problem with fuel pickup tube. I will pickup at dealer again. Dealer recommended I not let fuel level get low. Hopefully it is fixed but not letting the fuel level get too low is an unacceptable fix.
