I found this on serebii ! has a few locations to Ev Train at !

you can reset evs to !
This on yahoo answers :)
The only way to delete ev's is with the following berries I will tell you which stat EV's they lower.
Pomeg Berry: Lowers 10 EV's on HP
Kelpsy Berry: Lowers 10 EV's on Attack
Qualot Berry: Lowers 10 EV's on Defense
Hondew Berry: Lowers 10 EV's on Sp. Attack
Grepa Berry: Lowers 10 EV's on Sp. Attack
Tamato Berry: Lowers 10 EV's on Speed
All berries raise happiness also. There is no way to delete EV's any other way. I don't believe if you maxed out a stat and had some of the HP from the EV training it isn't possible to delete them with the berries.
