With the kit spur there's little choice of what pinions you can use. I run a 6.5 on a 22 pinion but if you're trying to run larger then it could be the mesh is too tight.

I was running mine and over jumped a jump landing hard causing the motor to move slightly causing the mesh to go slightly tight. After the run the car was stinking hot, nearly cooked the motor.

I run the belts loose if if they're like banjo string then that will be a contributing factor.
