Q Why is my R1 cutting out?
My 2005 Yamaha R1 keeps cutting out in the first few miles. It threw up an atmospheric pressure sensor fault, but a sensor change hasn’t sorted it. Alec Turpin, Horfield, Bristol
Answered by Charles Marvell, A Flitwick Motorcycles We had a 2004 R1 in recently with this problem, which also didn’t respond to a sensor change. So, I decided to try a new throttle position and position sensor on the throttle bodies. We then did around 40 miles of testing with no problem and no fault codes.
