Piston wrist pin fit?

Hi all - I’m putting new rings on my 2002 Yamaha 15hp 2 stroke and noticed one of the piston wrist pins goes in easier than the other.

one is snug and requires some force to push into place while the other goes in by hand and spins with two fingers (in the piston). There is no up and down play at all .. and it’s certainly not “loose”.

is this a major concern and I need to get new pistons, bearings and pins or can I reuse?

thanks!

ifthere is no "play" between piston and con rod then its ok.
why did you change rings?
puting new rings into used cylinder there is no sense.
