I have not rode the bike and have only started it few times to idle to for a few minuites. I decided to drain the original oil and change the filter because the original oil, I assumed, had never been changed.
After pulling the filter cover I found what looked like grease caught on the filter spring and some (not much) caught on the filter. This grease like substance has a carmel colour, opaque, and is very soft. It almost looks like plain old regular wheel bearing grease or a bicycle grease, but opaque and wax like.
It is not an oil/water sludge.
Any ideas what it might be? Left over assemby lub? A soap based thickener separated out of original oil. Also seems to have a low melting point, almost with the heat of your hand.
The old oil was quite dark brown in colour when drained.
Any insights welcome,
Thanks in advance,
