Lubricating '03-04 speedo cables on V11S'

Some '03-04 V11S & LeMans models have been encountering broken speedo cables (part code 01760491) and Ballabio & Cafe Sport (part code 01760480). Breakage has been occuring due to little or no lubrication usually near the elbow where the cable housing is threaded into the gearbox. Recommended (dealer) fix is to lube the cable, in which synthetic motor oil is being recommended.
