Do the berries that lower 10 EVs each also lower your stat points?
For example, let's say a lv 90 Gyarados eats 11 Kelpsy berries to lower its attack EVs. Will its attack actually lower down(assuming it had some EVs on attack) iF it doesn't, is it possible to keep "resetting" your pokemon's EV's then retraining them back again?

In Generations I through IV, the game applies EV changes during level up. This is why if you had a clean level 100 Pokémon and wanted to EV train it, you had to utilize the Box Trick. I'm fairly sure that because of this, you wouldn't experience a stat drop upon using the EV berries unless you used the Box Trick (I'm not certain).
However, in Generation V, EVs are applied directly after battle, so you could cause your level 100 Pokémon's stats to go up and down.
