Strange R1250GS engine noise.
I have noticed that my new R1250GS has a strange and unexpected engine noise.
It occurs when the engine is under load at all speeds and all gears. A typical circumstance - 50 mph in top gear when slightly opening the throttle there is a strange rattle/slight knock/grumble. It's always difficult to describe a mechanical sound but it's obviously fairly loud if I can hear it at 50 with a full face helmet and silicone ear plugs.
My dealer said 'it's still a new'.
My previous two water cooled 1200s never had this issue.
