Unfortunately the Africa Twin still has a drive-chain (apposed to a drive-shaft) and a drive-chain needs maintenance. Lot's of it. Mostly it is cleaning and oiling and that is a dirty job that requires a centre-stand (which the AT does not have). There is a alternative called a 'chain oiler'. A small device that deposits minute amounts of oil (one drop a minute) on the rear sprocket from which it is distributed to the chain itself.  And all this only when the engine is running.  Pam's is a 'Scott oiler' and works on the vacuum of the engine.
