I bought a 2011 WR125 that has been abused in a previous life, all the road wiring has been removed but not well.
 
We have fixed all the issues but are struggling with one issue.
 
With a flat battery the bike starts and runs before cutting out after 2 minutes, with a fully charged battery the bike will not spark at all so it seems the ECU does not like any charge coming from the battery.
 
The question I have is on some Japanese bikes when the ignition key is turned it steps down the voltage to the ECU/CDI allowing the bike to start, my bike has all the ignition stuff removed....does anyone knows if the WR 125 has a similar system?
 
Alternatively any ideas what might be up?
 
Thanks
Chris
