Example complaints
Fuel system: “In september of 2004 at approximately 5000 miles, the motorcycle began idling poorly and stalling. Had to turn off the key and then back on before it would start again. Yamaha replaced the throttle position sensor after bringing it to them twice which corrected the problem. I have almost 13000 miles on it now and it is doing the same thing again. It is a safety issue because it is distracting and hinders my ability to watch traffic and frequently stalls at traffic lights.”
NHTSA complaint #10129651, filed 2005-07, 5,000 milesElectrical system: “Yamaha 2004 FZ6 bike runs good for a while, and all the sudden the engine loses 90 % of its power, I have to turn the key off, then back on to regain power while in traffic, one time this happen I gave it to much gas to get out of traffic ,and I flipped the bike over in the middle of the street. It was my lucky day nobody ran over me. Looking at this web site , there is a lot of other FZ6 riders with the same problem, I have asked 4 Yamaha dealers if anyone else is having this problem and they all said no? …”
NHTSA complaint #10169691, filed 2006-10, 3,000 milesVehicle speed control: “1. Bike was badly hesitating starting off in 1st gear from a stop. 2. Turning the throttle to accelerate would sometimes pitch me forward on the start as the engine hesitated, then turning it a bit more would almost throw me off as it accelerated. 3. One dealership tried adjusting the throttle position sensor (tps) and it actually made the problem worse. The next dealership replaced the tps unit and it has been running fine since.”
NHTSA complaint #10118730, filed 2005-04, 4,400 milesEngine cooling: “Motorcycle shuts off after reducing throttle during deceleration and during shifting. Many riders of the same model motorcycle have reported the same problem. This is dangerous because the bike is w/o power and sometimes during downshifting the rear tire loses traction and causes the bike to slide sideways.”
