Found a cartridge of that grease just the other day, no idea why I bought it as I normally just have MolyD, LM, copper, nickel and silicon grease lying about. Got some red as well but not a big tin.
Kelly, look at where Honda put the grease nipple on the 550 swinging arm and just copy it. (look for pics on Ebay) IIRC it's 1140mm from either end, get a 6mm copper washer and lay it on the tunnel just above the weld seam, go up 2mm and drill in the centre of the washer, 5mm, tap to 6mm, locate nipple ( I used a straight small stainless steel one) then using a flat punch knock the copper washer to the shape of the curve of the tunnel. I usually weld a 6mm nut on for the nipple to thread into but thought I'd try this first.
