My JPS mild flare with a type 4 engine, a 15 gallon tank (full), but no driver, weighed in at 1860 pounds at the local moving company scale.
Not sure how accurate a moving company scale is at the low end. Ideally, scales should operate around mid-range for best accuracy. The other "free" scale around here is the weigh-in at the local land fill (my truck is 5310 empty). Haven't found a good reason to take my speedster to the landfill yet!
