Over revving the motor constantly (high rpms + low gearing = motor tops out very quickly and stays spinning at high rpms constantly when you are on the throttle).

Contact medusa and they will sort you out most likely, - I would do as the others suggest and swap it for a ~1600kv motor if you intend to use 6s lipo most of the time.

4s lipo = 1900-2200kv
5s lipo = 1700-2000kv
6s lipo = 1500-1800kv

As a very rough guide- 4 pole motors tend to perform better when span slower and geared higher, unlike 2 pole motors that work better span faster and geared lower to make their power/torque (least thats the impression I gotten over the years).
