I've a sakura (powaybke shopper MK2). It's dead. Battery's and motor work but no throttle or power. We think the controller has failed and the wires from the battery. I want to replace everything basically. Is there a controller I can fit that will work with the motor and PAS sensor and that I can fit a new throttle. I'd love to keep the brake sensor but only if possible.. does anyone know the wiring and can tell me what wire does what and what kit to fit. I'm clueless.. I have a 6 wire throttle I bought but again clueless as to how it goes. Kinda need a dummies guide to making it work
