G'Day Ross,
must be starting to get a bit exciting your end - not long to go now! ;)
My J160c weighed in at 123kg RHS and 120 LHS (no fuel), sorry I don't have weights with full fuel, but one would assume that it would be only a 3kg difference.
This weigh in included engine oil and the POH states the difference must not exceed 0.2% or 10kg which ever is greater. (I think that should say 2%, could be a misprint)
hope this is helpfull
regards
