Fuzzy Head

Hello all,
I recently bought myself a Mac motor kit from em3ev of which appeared to function perfectly when I did a short powered test of the motor and controllers. At the weekend I finally got a chance to start installing it properly and while modifying my torque arm I realised that the wheel would not spin properly. At this point it was resting in the slots on the front fork (upside down) in the air (not sure on technical terms) and there were no obstructions preventing it spinning. I opened the hub and took out the motor and could see no obvious problems. At this point I have not even removed the protective wrapping on the wheel rim so I know I haven't damaged anything.
I suspect a problem with the clutch but am not certain. When I spin the wheel so it spins as if coasting forwards it spins fine with almost no resistance. But a few times when I have tried to spin the wheel backwards it has jammed. Most of the times I have tried spinning it backwards it has a good amount of resistance. I think it may be normal to feel a strongish resistance force when turning the wheel backwards due to the motor being spun but can someone please confirm this is normal?
I would really appreciate it if anybody could offer some advice as to what they think the problem could be or what may be worth doing?
Is it safe to try adding some oil to the clutch?
Thanks
