This morning when I started my bike, it was idling unevenly between 1000-1500. I could hear it revving (by itself). I tried it in gear at a stop with clutch pulled in, and it was still there. After riding for 15 minutes and bike is warmed up, then, it is less noticeable and possibly back into spec as mentioned in F800 site.
"The idle-speed specification is 1250+-50 RPM, so anywhere between 1200 and 1300 RPM should be all right. Cheers, Andreas "
but mine quite noticeable at cold idle and idling at a wider variance mentioned at the start. It is getting colder as we move away from summer.
What could be the cause?
