I think it is the reflection of the air cleaner above and not a cut away. Nicely polished!
Obviously! Well spotted. What an interesting optical illusion.
Yes, had me fooled till I took a closer look Peter. I was thinking a cut away like that would be a little dangerous.
I think the oil leak from the crank seal is a common problem. Mine seeps, crankcase breathing issue? I also get oil in my air filter.
