Due to wear and tear, it's not the highest reading you can get, but what you want is for there to be no more than 10% difference between cylinders. This will show up potential wear patterns, leaning out of cylinders, etc.
Make sure the motor is warmed up. Pull the kill lanyard and crank at least 6 - 8 seconds on each cylinder. I always repeat right afterward to verify that reading.
