Step 3Assembly
Mount the motor:
1) Use the same location as the gas engine using as much of the original frame and existing engine mount as possible. I was able to use 2 of the existing motor mounts, and then added a 1/4 inch 4x8in piece of steal, which is bolted and welded to the frame.
2) Mount the motor on the rear swing-arm. Check out http://www.evalbum.com/type/MTCY for some ideas. Here is an example of a swing-arm mounted motor: http://www.evalbum.com/703
Controller, Main Contact, and Throttle:
Its is very important to mount a controller in a place that is going to get a lot of air flow, because these things can overheat and fry if your not careful. Curtis website has some really helpful information on how to mount and wire these controllers, this is a huge resource that most of the controller manufacturer offer so find yours and use it. I was able to mount on the side of the frame where the tool kit used to be. This provides easy access and lots of crisp cool airflow. The main contact was mounted on the inside of the frame, close to the batteries and controller. Below is a detail wiring guide, this is probably the most important part of this instructable and the part that gave me the most problems during the build. The main contact should be mounted in a place that is easy to get to. I put my inside the body of the frame, this was a mistake. Hard to get my big hands in there and I can never see whats going on when I am moving wires around.
Throttle should have 3 wire red/blue, brown, and black. You will need to use a multimeter to test which leads give you 0-5k ohms or resistance, these wil be connected to the controller. In my project these where the brown and red wires. Then the black wire need to be connected to battery negative or negative terminal on the main contact.
Batteries:
Batteries should be wired in series this means positive on battery 1 to negative on battery 2 and so on... look at the picture, I'm told its worth a thousand words.

Maybe a electric motorcycle with front and rear hub motors...Thoughts?
