Now the air cleaner. Again the Honda has an unusual design by modern standards. The still air box splits horizontally along the centre line and is held together with two wing-head bolts which are unscrewed from underneath. With the two bolts unscrewed the lower half lifts clear, revealing a brand spanking new air filter element. The two bolts are shouldered, rubber mounted and retained captive in the air box with washers and split pins - another example of Honda's quality engineering
