Great team, but there is not much I can say.
Servine
For Servine, give it 4 Hp / 252 Sp.Atk / 252 Spe Evs.
Pinsir
Great.
Moltres
Moltres need HP Grass. It covers rock and water types that would otherwise wall Moltres' STAB. Replace Extrasensory for it.
Lanturn
Lanturn really doesn't need so much Hp evs because of it's great HP stat already. Switch it for 52 Hp / 252 Def / 206 Sp.Atk. Signal beam is also useless; replace it for ice beam.
Hitmonchan
I see what you're trying to do with Hitmonchan but sadly, the 20% boost only goes so far. Mach Punch goes up to a decent 72 with STAB. Elemental Punches also goes up to 72 but poor Bullet punch is at 48. Moltres could use some rapid spin support so stick that in instead of Bullet Punch.
Mespirit
Not much I can say but to add leftovers instead of Lum Berry because you have Heal Bell on Lanturn
