Infamy bothers Rao's heart. Someone instructs Rao to quickly tuck the motor under his arm.

This couplet humorously depicts Rao, whose disreputable heart bothers him. The second line is a direct, witty piece of advice: 'Rao, just tuck that 'motor' under your arm!' Here, 'motor' isn't a vehicle, but playfully refers to whatever impulse or problematic desire stems from his 'infamous heart'. The suggestion is to keep it discreet, control it, or perhaps hide it away. It’s a lighthearted jab, urging Rao to manage his troublesome inclinations or the consequences of his actions with more discretion. It essentially tells him to keep his 'troubles' or 'desires' in check and out of sight.
