Red oil in case?? What is it?

[tsmith]

I purchased a 2010 EC 300 with about 4 hrs on it. I dont think it even had a full tank of gas ran through it. Im planning on taking it out on the first real ride this coming weekend so I thought I would put fresh oil in it.
When I drained the oil I noticed it was red similar to transmission fluid. Has anyone heard of this? What could it be? I dont think the original owner mistakenly put tranny fluid in it. He had several street bikes and dual sports. But it sure makes me wonder what it could have been. I never had any problems or noticed anything funny when I had it out for a short ride right after I bought it.
I replaced it with 10W30 Lucas motorcycle racing oil. So, I should be good now.
