i would definitely replace the stock controller with an LBD14 or similar - search ebay for LBD14 or check TNC scooters site (ebay usually cheaper).http://tncscooters.com/index.php?route= ... uct_id=159
The LBD 14 will take up to about 50 volts despite its 24 volt rating, and is slightly smaller than stock controller - so it fits nice and doesn't even get warm at 1200 watts, so unimaginatively I covered mine with a bit of plastic and black duct tape. Looks fine and is reasonably splashproof...
You just run the two main red/black thick wires to the battery, another two (blue and white thick) to the motor, and the two to the keyswitch (or just short them together if you don't want to use your old switch).All the other connectors can get taped up and stashed out of the way...). And you need to connect the throttle - any three wire one will do. If your throttle has a fourth LED indicator wire to show charge state, you can just leave it off.
Throttle usually have a red and black that match the controller, so join those. Then the tird wire will usually be blue or green for the throttle signal.
You can swap controllers in about an hour. There is a document at the link for download.
Its a much nicer bike when you can make your own decisions.
The standard battery will give about 15 amps to the controller. When you upgrade to Lipo, the controller will pull up to its maximum of 30 amps - a big boost in torque (which drives acceleration).
