No spark I have one of these motorcycles and have tried everything to get a spark from the ignition, I have replace coil, wire, plug, battery and jumped a new cdi box as well as a new alarm system. Still o spark and it is only reading 1 volt where the voltage goes into the the coil.

How stock is ignition and charging system?

Assuming stock ignition, check for near battery voltage (within 3 volts or better) at the positive side of the ignition coil while the ignition switch is in the run position.

If no power at coil positive then likely a fuse has blown or other open circuit... miswire or open ignition coil resistor wire.

If power at coil positive, check for power at coil negative. If near battery voltage at coil negative then points are open and you should get spark at ignition coil secondary by flashing the coil negative with a jumper wire to ground.

Comment for further assistance.

Possibly a bad ignition coil. Check the connections at the ignition coil,make sure they are clean and tight, If so,..then most likely either A: the ignition coil is bad,or B: the pickup on the stator rotor is bad or the rotor could be rusted on the raised portion where the pickup get its signal.
