Procedure is as Paul says but maybe the swinging arm out as well. I had the swinging arm out recently to replace the bearings and repaired the cracked brackets in situ. I seem to remember thinking at the time that the arm would have to come out to remove the tanks as well but I may be wrong. Suggest you beef all 4 of the mounts up as per the Bunny modifications or you will possibly be taking the tanks out again in a year or two. Good luck and let us know how you get on KankeL.
