The work continues to remove vestigial components that supported the internal combustion engine.
The list of removed parts includes the oil tank (and 14 quarts of oil required for the dry sumped, air cooled engine), the oil cooler, fuel vapor canister, fuel filter, fuel pressure accumulator, cruise control servo, starter motor and electronic ignition module.
Twenty feet (6 meters) of copper pipe comprise the oil cooler. The tubes run from the back engine compartment along the rocker panel to the front passenger wheel well. The coiled bit is sometimes called the trombone.
The right rear engine bay cleaned after removing the oil tank. The grease and dripping oil will not be missed.
