One tip for rebuilding a motorcycle engine is to secure the bike before beginning. It may take much torque for the user to undo the various motorcycle bolts, and failing to secure the bike and its front wheel may cause it to move laterally while the owner or mechanic works.
Another tip for rebuilding the motorcycle engine is for the owner or mechanic to drain the gearbox, engine, and radiator fluids into suitable containers and to keep the containers separate. For best results, the user should let these fluids drain out overnight while ensuring the motorcycle is not near any open flames and that the containers have suitable capacity for the fluids they are receiving.
The user should disconnect the motorcycle's battery, disconnecting the ground lead first. When reconnecting, he must connect the motorcycle's hot lead first.
Before removing the actual engine, the user must loosen the motorcycle's engine mounting bolts and its related plates and then remove them. Before removing the final bolts, he must make space for the parts on a nearby bench. For maximum safety, the user should enlist the help of another individual. The next step is to straddle the bike and, with the helper balancing the engine, lift the engine to one side before going to the side where the user plans to remove the engine. While the bike is in this state, the user should inspect its engine mounting plates and frame for any defective parts that may need to be replaced.
