What owners report

At 9m miles, my 2004 yamaha fz6 began to exhibit the following: 1) after approximately 30 minutes of operation, erratic and prolonged periods of rough idle at 500 rpms instead of the normal 1300 rpms 2) motor would stall during gear changes, even at highway speeds 3) during these times, the smell of gasoline was…
After the motorcycle warms up (approximately 50 miles of riding), it will stall out and/or sputter when the clutch is engaged and/or shifted into neutral. Last july it stalled out in the middle of a right hand turn around a red light, resulting in the back tire loosing traction and causing a crash.
Motorcycle's idle rpms change abruptly, to the point of stalling when at slow speeds. This abrupt change was the source of a rear end collision. The bike had been taken in previously to the dealership on multiple occasions but no corrective measures where taken, as the problem could not be reproduced.
It stalled once while I was on the way to work and I dropped the bike before I could catch it. I've had friends tell me that it is a tps (throttle position sensor), but the motorcycle is out of warranty and I don't have the money to take in to be checked. That would be almost $100 and they may not find it.
Hello, i ride this Yamaha FZ-6 motorcycle and I experience poor idling and engine stalls during riding, and last time this nearly led to accident, because the motorcycle slowed down in front of an overpassing automobile. I have bought this bike imported from USA. I am situated in Bulgaria, Europe.
The headlight and starter were replaced three times. On august 23, 2008, the battery failed again. The vehicle was towed to the contact's residence. She charged the battery for several hours, but the vehicle would not restart. The vehicle will be taken to the dealer for a diagnosis.
