I buy my first kitfox ii with hks

And i have a surprise when i check the weight of the plane 568 lbs empty

Is normal? On the kitfox web site say the empty weight is 450 lbs? Diff of 118lbs

If i put 36 lbs of fuel on each wing ,and 7.2. Lbs for,upper tank and my weight is 175lbs.

950-568-36-36-7.2-175= 125 lbs for copilote

What the solution.....put half fuel on my tank, increase gross weight , never fly with a copilot.
