I just recieved a set of SLP pistons for my vmax 500 and they don't have the hole on the intake side like the stockers did??? Stock pistons had a small hole about 1/3 way up the skirt,the hole is probably 1/4-1/2 inch round.

I didn't know that Starting Line made pistons?
There should be some kinda mark on top, if not look at the ring grove for the pins they go towards the back.

It has the arrow, I just wonder if it will effect the way it runs without the holes.I know what way they go in,just was curious if its going to run as good as the stockers.I am waiting for the cylinders to get back from getting re nikasiled.
