Polaris Xplorer 400 38A Piston...what size?
I'm doing a top end rebuild. Previous history is pretty much unknown. The piston is stamped " 38A "
At this point I'm not sure sure if that's s standard or over bore. In the past with other machines I have always known what bore size was at and would always order the next piston size up, drop the piston and cylinder off at my machine shop and they take it from there.
