Hi all,
I have a backdraft 8E. I am considering a new 18 tooth pinion gear. What is the appropriate pitch?
Also, I've been considering the cooling fan for the motor. Is it worth the effort to install it? How much effect does it have on the battery life?
Cooling fan on the motor won't have any effect on the battery life. It will have effect on motor temperature.
