Hi,
My 2011 XT660Z (41 00km) is making a squeky noise while idling after a cold start. The noise seemed to go away after the engine warmed up. Is this something to be concerned about?
Bike has always been serviced at a yamaha dealer. Previously at 40 000km. Haven't ridden much during the winter so am I imagining things or is this an unusual noise.

Thanks already in advance! All help is appreciated!
