My wife's ST1100 has started to become a bit difficult to shift into neutral and from 1st to 2nd when the bike is up to temp. I've been replacing the clutch fluid annually and carefully but the bike does have 73K miles so it's possible that something is showing it's age: master cylinder, slave cylinder, clutch plates, clutch springs? But I thought I'd ask here for steps to troubleshoot which may be helpful to others. I also looked in the ST1100 articles and didn't see anything of the sort.
@Igofar - It has Rotella 15w-40 in it and is pretty recent
