Wheel is not properly tensioned. Wait two weeks for a new wheel from Fuji, then check the tension. If not appropriate, then you need to give this wheel to a good wheelsmith and let this person re-tension the wheel.

I prefer to keep the minimum tension north of 130 KgF for a heavy rider. The spoke tension will decrease at least 5-10% after the first 400 miles. I don't use a gauge...just years of experience in the hobby.
