[QUOTE="TM-Frank, post: 734783, member: 20961"] Di I understand your profile correctly? You have already sold the bike or what? Nevermind, the different piston sizes are needed because when they get their cylinders from their supplier thes are not all exactly of the same size. One may be 70,00 mm and another one is 69,99 or so. Therefore they have different piston sizes too, so they can equip each cylinder with a piston that gives the correct clearance. When one of the cylinder nuts in the coolant cavity is rounded then you have a problem. I don't have any idea how you could get it off then. I always used a 14mm socket on which I reduced the outer diameter with a grinder, so that it fitted into the coolant cavity. [/QUOTE]
