I may have been too literal or technical..but the crank/rod/piston is all lubed by the the gas/oil mixture coming in the intake.
the oil in the "case" is just in the transmission half...thus when a crank seal goes out on a two stroke it starts sucking in the tranny oil and smoking very heavy..and if you run the 80wt tranny oil like i do in my older bikes the smoke has a more distinctive smell then the injector/premix oil.
