Tried taking the motor apart anyways yesterday, and found one of the crews were horribly stripped from the manufacture.
Unable to gain access, I decided to blow some air through the motor while two of three rear screws are removed allowing air to pass through with little restriction. This seemed to help and felt less gritty. Then applied some fresh lube and put the two good screws back in.
Everything worked out fine and got some timed speed runs. However, after a couple battery packs, I decided to put the stock motor back in for a while because my buddies have been driving this one and with the 5400kv plugged in, it was to powerful for them.
