I bought an Odyssey pc680 and I want to move it to sit under the gearbox and behind the oil sump. i bought an aluminium tray from ebay, and made up some brackets to weld to the frame. A local welder laughed at me, when he was done scolding me for 'making a pig of a beautiful old classic bike like that'. I told him it's only beautiful because of the countless hours I have spent with a toothbrush and degreaser, and all of the expensive miller oil I have put through it. he wasn't having any of it and will not weld anything to the precious (only 6 billion of them made) R80. Anyway, when I calmed down I thought the old fart might have a point, even though his bedside manner leaves something to be desired! I still want to relocate the battery, but without welding. I tried the exhaust clamp (the one that joins the headers to the silencer) but the diameter is too large and it won't clamp tight. Has anyone tried this and what did you use? it would be handy to find something like an exhaust clamp of the right diameter (I must actually measure it) to for without getting the angle grinder out.
