I've been using an Odyssey PC 680 Battery for 4 years and it's apparantly getting "tired". Would like to go with a larger battery. The PC680 is the smaller battery. I'm cranking a R100S motor and running a couple accessories. My bike has the large battery box (1974 R90/6 Frame) so the larger PC925L Battery should fit. The "L" designation apparently is for a reversed pole arrangement. I take that this means that the battery can be laid over to fit in the BMW battery mounting frame, with the terminals towards the front. The PC925 is heavy...25 lbs. Looks to me like it will be a very tight fit getting it in there. Anyone around here installed this battery with the "reversed" arrangement? Can a guy "shoe horn" it in there without disassembling the bike?
