Weekend Mechanic host Bruce Bonebrake goes through some basic motorcycle maintenance procedures on a 1978 Yamaha motorcycle. The bike is examined from end to end, and each area of maintenance is discussed. Both tires and all fluids get replaced. The air cleaner is replaced and a new cam cover gasket is installed. The bike also gets a new set of muffler pipes. Finally, the old worn seat cover is replaced with a new leather cover.
