Speed passion reventon pro 1.1 issue

[sfry61]

Hi

So I think I have speedo issues. The motor is cogging. Took the sensor lead off and it runs fine. Put a new lead on and it's still cogging. Does the same with my new motor. What do you think?
The motor gets hot very quick. It's just been sat since I last used it. It was fine the last time I used it.

Any suggestions?

Could be sensor board in the speedo?
