From what i can understand is that you are using the high speed spur with a 27T pinion,is that correct?
If you do, then i suggest to buy a bigger pinion a 29T (This pinion comes in a set of 2 pinions 28T&29T) and a TB03 64T spur.
This will bring your final drive ratio (FDR) down to 5.74 instead of the 6.55 FDR you have now.
The motor should be ok with this lower FDR.
This would cost you less then $20, much cheaper then buying a new motor.
Just keep in mind that you oftenly need to check the temperature of the motor after a few minutes of driving.
Hope this helps
