2005: “My 2005 FZ6 ran flawlessly till 4000 mile then the idle was dropping to 600-800 and then would just die. I would turn key off and turn key on again and restart and it would run fine. It happens twice a week. Once on wet pavement it was feeling boggish I pulled clutch to see and it was 600-800 and died. I let out clutch and almost lost it. I read about several other owners experiencing same problem and some rumor it to the tps sensor.”

NHTSA complaint #10168366, filed 2006-09, 4,000 miles

2004: “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.”
