Piston A,B?

This assumes the cylinder has not been replated and possibly refinished to a slightly different size (without being marked as different).
 
Thanks for the replies. I bought it new last year. I would hope it's a matched set from the factory

John, Cylinder is marked above intake. Being that this is the first top end replacement on the bike, you should be good with the same piston diameter that is marked on the cylinder.
 
Go for A. For the same money why would you settle for a B?


Fortunately my wife didn't apply the same logic.:o
