Clean the air filter - Royal Enfield
Bikes are fitted with either a paper or foam type air filter element. If it’s a paper element, you can tap it to dislodge dust. Foam elements need to be washed in solvent, then dried and re-oiled. If the element is very dirty or damaged, you will need to fit a new one.
