close-up view of a dirty, likely used, motorcycle engine. The engine block is gray with cooling fins. Attached to it is a carburetor, also appearing worn and dusty. A spark plug is visible with a gray boot connected to it. There's a metal bracket bolted to the engine. The overall scene suggests a garage or repair shop environment due to the engine being detached and its condition.
