Hi,
I own a Jabiru LSA, empty weight of 270kg and with max weight of 430k. It doesnt give much to play with.
So I can put 2 average people in, min fuel and taxi round a bit, or a lightweight pax and enough fuel for joyflight, or by myself with 65 litres and overnight bag.
We have enquired about increasing the weight limit to 470kg, but were told that there wouldn't be any weight increases available on these older models. So we play with what we've got!
Hope this helps
