So i decided to fix up my Lazer sport 50cc again. i upgraded it with a pollini kit. I pushed it down a steep hill but it wouldn't start. The headlight would dim and the engine would rumble a little. But the bike would not spark up and keep running by itself. I figured it's the external ignition coil. Does anyone know if both sides of the ignition has to be bolted. because my frame can only fit one. The bike used too run fine when it had the old coil.
