      Guide Steps

      Step 1 — Remove the air filter housing

      Using a screwdriver, loosen the two Torx T25 screws on the air filter cover.

      Step 2 — Clear the air duct

      Disconnect the oil vapour breather.

      Step 3 — Cleaning the throttle valve

      Spray brake or contact cleaner on the throttle and use a soaked paper towel to clean it until the body and edges are clean.

      Step 4 — Refitting the airbox

      Replace the pipe as far as it will go.

      Step 5 — First restart

      The first restart after cleaning is likely to fail and/or require many, many revolutions of the starter motor, even if the engine is warm!
