Hello. I have a F4i and have a problem with revs. The problem is that revs are floating. Revs can go from 1.2k to 1.6k but when they are floating they float with 0,1k interval (for example from 1,3k to 1,4k). It is not something that does not allow me to ride but I just want my bike to be in good condition. When the bike is cold after the starting high 2.5k revs, revs fall down to 1.2k but when the bike is warm, they go up to 1.5k. Also they can randomly fall down from 1.5k to 1.4k and even 1.3k. Yesterday they were floating even from 1.5k to 1.6k revs. Maybe someone has had this kind of problem?
You can see in this video what I mean by floating revs - https://streamable.com/j9ypn
