what size piston are these?
Hi I have a seized ´98 gp1200 and I´m trying to find out what size the pistons are. The only thing thats written on the pistons are "65u" on one side then the letter "F" on the other . Thanks, david

they are 84.0mm. You are going to want to jump to next size if the the walls are scorn. Um i would go 84.25mm. That would be the next step. I would either do pro-x pistons, oem, or wiseco. If doing wisecos give a little more clearance. And Always bring your pistons in with you when getting them bored so they can match up the pistons to the cylinders.
