My bike is a 2007 FZ6-N S2, 38000 km on the clock. Recently it’s been making a whirring/winding noise in 3rd gear under drive when moving at 43-50 kph (26-31 mph), rising in pitch, until it disappears after 50 kph. The noise happens only when on the throttle, and goes away when clutched in. And only in 3rd gear. Oh, and it seems to come and go, apparently depending on engine temp. It’s most noticeable when cold or very hot, but less audible when at a nice 76-84 C (168-184 F).
Chain is lubed and properly tensioned, oil changed about 1000km ago (Yamalube 10W40) and checked frequently.
Could it be a transmission bearing issue? Seems unlikely as it only occurs in 3rd gear, right? Worn cogs? It’s kind of driving me nuts, as I don’t want to take it to a mechanic as splitting the case is an expensive job.
