So got around too bobbing the rear loop today. Wanting to do most the work on this project myself I bought a gassles mig from bunnings and after a few test runs on some scap I managed to get something that resembled a weld haha. Luckily it all will be covered by the seat. I mocked up the z50j seat pan and am pretty happy with the overall shape of the tank and seat. Webbike also came through with some goodies. Taky throttle, levers, electrics, gear shifter and kickstart all arrived today.
