      we can mostly rule out oil coming out the carbs,maybe premixed spit back and the hose from the airbox to the lower crank bearing is unhooked. the oil is injected ito the reed box area.
      like I say I do a consumption test. the output spec and rpm is in the SM.
      multiply it by six and the consumption equals the output.

        Does oil come out of the airbox through that hose connecting to the crank bearing?

          If it is not connected, it will be oil and fuel mixed.

            We are talking about the line that connects to the bottom of the airbox correct? Item 26 in the diagram.
