“I am aware of several dozen people who have had the same problem I am now having with failure of the throttle position sensor (tps) on a 2004-2005 Yamaha FZ6. This causes a new vehicle to run poorly and stall frequently until the part is replaced.”
NHTSA complaint #10157605, filed 2006-05, 4,800 miles“1) exhaust pipe turns red after normal use, gas tank vent line is above exhaust pipe, back fires 2) fire hazard 3) taken to shop and Yamaha could not recreate problem and I was charged for diagnosis - the problem still exists Yamaha does not acknowledge that their is a problem with this atv - they could not recreate the problem and therefore assume it does not exist, this atv has done this since I brought it home new from the dealer. The risk of fire or exploding is high since the exhaust pipe is very near the fuel vent.”
