    Wouldn't it be easier to just buy the piston from millennium

    I will end up buying the new set of pro x pistons from them regardless. Need to know what size is better and why.

    There should be a number stamped on the jug,where the head mounts,that number should represent which size piston you need,I'm sure they can fit whatever size,if all else u could get the bigger one since they could bore it a few thousands if they had to

    It's hard to say because they have been replated and could have possibly been bored out. I saw in their catalog they offer 4 sizes which increase in size by .01mm and they offer an oversized at 80.50mm,what pistons are currently in it now,if they are pro x they should have some kind of marking indicating the brand and size.are you replating from normal wear or did u trash a cylinder

    If your thinkin that a certain size is "better" than another the answer is no,they only very slightly in size for a more exact fit,since not all cylindersare exactly the same size from the factory,yamaha,which uses pro x pistons,has them in four diff sizes that slightly vary to get a tighter fit.where if you were to buy any other brand pistons where they only sell one standard size,meaning the cyl to wall clearance can slightly vary between the cylinders where there is the possiblity of some either being too tight or too loose
