To replace the spark plug on the Triumph Bonneville, locate the top of the cylinder, accessible from the right side of the bike just below the fuel tank: the spark plug can be removed from its seat using the appropriate socket wrench. This way, the old spark plug can be taken out, and the new one can be inserted, securing it to the top of the cylinder with the socket wrench.
