Tubeless conversion on the 450, anyone actually running one?

Stock 450 comes with tube type spoked rims, 140/80-R17 rear which apparently is a pain to find on the road. Saw a Team-BHP thread on converting to tubeless using the tube flap technique, seems like a proper weekend job not just tape and sealant. Anyone here actually running this conversion daily? How's it held up, any pressure loss or sealing issues after a few months, and did you notice any change in ride or handling after.
