2007 Yamaha YZFR1 Fuel system Problems

“I almost dropped the bike with my son on the bike with me in a intersection and was almost struck by another vehicle due to the loaf in throttle in first gear. The bike stumbles and misfires from idle up till around 2000 rpms. This has happened several times. I have notified Yamaha directly with no help. They started changing out the computers in the bikes then they stopped. I just bought the bike with the extended warranty. This is a very dangerous problem especially having my child on the bike when this took place. …”

“Purchased 2007 Yamaha YZFR1 last september. The bike exhibited a lag in the throttle around 5,000 RPM, and the engine will also stall at random, usually at the worst time. This bike has stalled at least 20 times at intersections, and stalled another 6 times just yesterday! The throttle lag issue has been fixed by a dealer. The stall has not been fixed. The stall problem scares me. It may lead to my death!!! Yamaha needs to fix this now!”

“I purchased a 2007 Yamaha YZF-R1 about 3 weeks ago. When riding this motorcycle in 2nd gear at 5500 RPM (approximately 45 MPH), there is absolutely no throttle response for 2 to 3 seconds - almost as if it is running out of gas. My dealer contacted Yamaha and while describing the defect was interrupted by the Yamaha representative... Let me guess, 2nd gear at 5500 RPM? The answer is tmdt... That model does that. That's the way the computer is programmed and there is no fix. The bike should be ridden the way it was meant to be ridden to avoid this. …”

“I have a 2007 Yamaha r1.just got it 2 week ago.and I was riding about 50mph and try to pass a car and hit the gas and nothing happen,no responce almoust got hit by a car on the pass becous there was no responce on the gas.so I try the same speed agen with nobody around and it happen more time.I call the dealership where I got the bike from and they dont know anything about it so they say.the bike has 91mils its bramd mew but I pay $12,000 and thats what I get thats not right and almoust got kill too.aomwbody has to do something before theres somebody get heart.”

“The motorcycle at apprx 5500 rpms (45-50mph) in second gear has an extreme lag issue. You can turn the throttle but the bike will not respond. This is a serious issue due to taking away control of the vehicle making it impossible to maneuver through traffic or matching speeds of traffic. This problem almost caused me to lose control as well in a corner when becoming unresponsive to the throttle.”
