hi can eney one tell me wy im getting no spark on my peugeot speedfight 100cc. i was riding it the over n ight when it just cut out on me. dont think its cdi because iv got a bypass on it so could it be the spark plug coil because iv tested the two wires wich go to it and they hav power to them just no spark from coil thanks.

very unusual for the bypass unit to fail(assuming that its an aci 100 unit) you definetely sure you have power at the coil? if so i would check the ignition pickup in the engine, as i have stated already before on here, the 8mm bolts that compress the 2 crankcases together, can sometimes come out and damage the stator and pickup
