Welcome. I saw that bike when it was for sale on kijiji...it was down on the peninsula, correct? They are pretty durable machines all around. I doubt that bit of dirty fluid will do much....but nice to have fresh stuff. See the thread on the tendency of those fairing mounts to loosen over time. It's an easy fix but best to be informed. I'm just down the road from you in Hamilton. I rarely see a K bike on the road around here.
