Oil leak had me confused!
I had an oil leak on the ZZR 1100. I was having a little difficulty identifying where is was coming from. There is a small hole in the bottom ogf the water pump and oil appeared to be coming from there. On further investigation it turned out that the seal on the drive shaft had failed causing oil to pass. I also searched online and found out that a few owners have had this issue. Oh well, learn all the time. Now all fixed and as good as new.
