I was saying IF you bore it too large and go with a larger sized piston you may not have enough fuel to keep it alive.

More air without more fuel means leaner operation, higher piston temperatures, possible engine damage.
Without more fuel, you aren't going to get much more power from a displacement increase.
If you want to maintain reliability on a Polaris Ficht engine, don't change anything internal to the motor.
