From MCN web:

"The second Safety Recall concerns the Throttle Position Sensor fitted to certain YZF-R1, FZ6N/S, FJR1300/A, TDM900/A, MT-01, XV1700PC & XT660R/X manufactured between 2002 and 2006. In a small number of cases, the idle speed may become intermittently unstable, causing the engine to stall.
In the same way as the XV1600 Safety Recall, owners of the affected machines, held on our database, will receive a letter very soon advising them of the steps to take to have their machines rectified. They can continue to use their motorcycles in the meantime.
On behalf of the Yamaha Factory and Yamaha Motor UK, we would like to apologise to all affected customers for this inconvenience and assure them of our best attention to rectify the problems at the earliest possible time."
