Check you throttle cables as well. They may be in a bind or just a sharper than usual bend. You're carb spring is what pulls the grip back to zero. If those cables are in a bind just a little, it will cause your symptoms. I've went from my factory buckhorns to 24" drags to now 30" drag bars. It all just takes some fine tune adjustment of cable routing, grip clearance, and fudging.
