1. Locate the right side of the motorcycle, near the front of the engine.
2. Look for a small, metal plate with the engine number stamped on it.
3. The engine number is typically an 8-digit number, and it is usually located on the lower right side of the plate.
If you are still having difficulty locating the engine number, you can refer to the motorcycle's owner's manual or a Haynes repair manual for specific instructions.
