Tip & How-To about Motorcycles
Cleaning (de-coke, de-carbon) an exhaust header, expansion chamber and pipe is a periodical must to reap full advantage of the engines capabilities, that is often overlooked. A simple, quick and cheap method is to remove pipe from bike (and muffler) and place a length of cable wire (old clutch or speedo) or the metal shroud that surrounds it (stripped of rubber sleeve) long enough to exit both ends by 300mm (12"). Attach one end to drill chuck, Spray WD40 liberally into pipe and roll around till inner surface is covered, and spin drill with a slight in and out motion. A few minutes of this and then rinse out with water into a rag covered basket with a garden hose spray nozzle. For your health and safety, it may be wise to wear gloves and goggles. See results below. Note: Two old expansion chambers have been here cut for illustrative purposes!
