The piston ring gap for a Yamaha FJ1200 depends on the specific model year and service manual specifications. However, general guidelines are:

- Top Ring Gap: Typically around 0.20 - 0.30 mm (0.008 - 0.012 inches)
- Second Ring Gap: Typically around 0.30 - 0.45 mm (0.012 - 0.018 inches)
- Oil Ring Rails Gap: Typically around 0.20 - 0.60 mm (0.008 - 0.024 inches)

Always measure the ring gap by placing the ring inside the cylinder bore and using a feeler gauge. If the gap is too small, carefully file the ends to achieve the correct clearance. Always refer to the specific service manual for precise specifications.
