Vglide to controller, is this right?

[larryh]

After reading all I can find here I think I know what I need to do. I am working on an 89 cc and more torque is the goal. I've been told by the local "experts" that lifting a 36 volt cart is a no no, but I think they are wrong. I understand that 48 volts is better, but I've got nearly new batteries and I would hate to drop the money for 6 8volts. That being said, I will run 36 for a while until I need new batteries and then jump to 48. Am I right in my understanding that to uprgade to a high torque motor and controller that I will need to get rid of the v glide and the resistor coils and and simply add the controller and a pot and rewire everything with 4 guage wire? Those that I have talked to say that this is a headache and a really bad idea. I don't see that. Am I missing something?
Thanks.
