I used a 95 spur due to the 88 spur being too small and can't mesh with the pinion properly. Is there something I'm missing ? I understand the torque difference between the motors. It's just too big of a difference if it's only the torque difference. If it's necessary, motor temps are 130 on 17.5 and 125 on 10.5 on average and I use 64 pitch. Thanks for helping
