Maybe a valve cover gasket leaking oil on the exhaust manifold?
the crazy thing is the motor is perfectly clean..no visible oil leaks anywhere. I'll lay down next to the scoot with a flashlight and look all over it and i can't see any leaks...but i can definitely smell it.
There is grease inside the variator (no grease around the sliders, but grease on the inside where the variator slides over the crankshaft) and grease in the same place on the driven pulley. wondering if some is slinging off inside the cvt and cooking?
I'm not quite motivated enough at this point to pull some plastics and the cvt cover to check..I'm sure I'll pull it at the end of the riding season.
