Hi All
New to site and mini bikes! just purchased a trial bike with a LIFAN 140cc engine which will not start it has NO SPARK, it has a 5 pin CDI i will list the steps I have taken to sort the problem!!
1 killl swith removed wires joined together
2 fitted coil unit to another bike (this bike ran no problems with coil from non running bike 140cc with no spark.
3 fitted extra earth point to coil earth lead (to frame)
4 removed magneto/stator cover check wires attached all ok
5 tested ac voltage from mag/stator red/black wire and blue/white wire, volt meter measured around 40volts when kicked over (checked this against the running bike which also had around 40volts when kicked)
6 tested the resistance of the mg/stator same wires as above measured 470 ohms, the running bike showed 370 ohms but this bike is a 125cc lifan engine.
So Im at the point where Im not 100% sure if the fault lies with the CDI or the mag/stator Im thinking that it maybe the CDI as its getting an ac voltage??
Any help I will be very grateful,
Regards
Stuart
