I know the motor has more in it should i jump to a 15 or should i go one tooth at a time. I have all the way to a 18 if needed but i dont think that will be needed.
I ran a 12 indoor and 13 outdoor with my old sc4x 4.5 so I would think you should start with at least a 13 indoor or 14 outdoor and go up as temp allow. You may end up at 14 indoor and 15 outdoor but go one tooth at a time.
You can get to the pinion screw pretty easy is you have a ball tip 2mm. Or dremel out a section in the plastic above the pinion to get a regular hex in there.
