Question about 2007 Yamaha YZF-R1

1 Answer

After a short highspeed acceleration and then suddently drive slow or just stop for traffic lights, sometimes the engine just doesnt rev anymore. Then I have to open the throttle very wide just to continue at slow speed (on/off not smooth at all). When applying, in this problem situation, clutch the engine dies real quickly ( I see the rev meter drop to zero instead of falling to idle revs ). After turing off the engine and wait for a few minutes I can drive normally again. ( there was enough fuel in the tank at all times ) Model and make: Yamaha R1 (2002/2003 model)

I have a 1999 TERRANO QD32ETI engine and the problem which the local agents and private mechanics cannot solve is that when it's on the highways the engine performs well; that is it accelerates perfectly. However, when the vehicle comes to a dead stop, and you go for a quick take off the engine cuts out; it restarts quickly; now,when you make a slow acceleration after stopping the engine does not stall, but this can be a dangerous situation when crossing traffic on the highway or moving off from the traffic lights. We checked the computer, fuel pump and the injectors; our opinions differ and somehow
we feel the problem may be the fuel pump. We would appreciate your comments. Our many thanks for your kind assistance. Thanks Tony.

These codes indicate your accelerator position sensor has malfunctioned. The computer has gone into limp mode, which allows you to drive to safety without damaging the engine. The computer is unable to determine how far you are depressing the accelerator and doesn't want to over-rev the engine. You need a new sensor.

Accelerator has surged many times, sometimes while


Did the 'Check Engine' Light come ON? Whenever the 'CHECK ENGINE' light comes on, the ECU (Engine Control Unit) sets a Diagnostic Trouble Code (DTC). These codes identify the particular engine management system which caused the light to come on. You'll need to use/find an OBDII (On-Board Diagnostic) Scanner to retrieve any code which have been stored in the ECU computer. Afterward, we might be able to help you DIAGNOSE and perhaps eventually fix the problem.

Over-revving in 5th at 75mph all of a sudden


If the car rev'd up but did not speed up at the same time the clutch is starting to slip. Check the adjustment and recheck driving. When the clutch starts to wear this is how they act, only most people ignore whats happening and keep driving till adjustments won't fix it and the clutch has to be replaced. Have adjustment checked and keep an eye on it and hopefullty you won't need a clutch yet.
