Hello, I bought YB125 last year and convinced company to print me wiring diagram and technical specifications. I scanned it and I'm posting it for you. Images are in resolution from scanner, they all have 9.5MB. Preview: Links to big images: Wiring diagram (3.5MB) Key to diagram Technical specifications 1 Technical specifications 2 Technical specifications 3 Technical specifications 4 Technical specifications 5 Technical specifications 6 Technical specifications 7 I hope it will be helpful to someone. If anybody has information about hacking ECU or other usefull information about EFI on YBR125, please post it. I discovered one thing, fuel injector make clicking noise that can be misidentified as too large valve clearance I'm wondering how strong alternator is? How much amperes can I safely drain from it? Is there way to hack EFI and reprogram it? Some information about diagnostic tool? Protocol, specification of diagnostic interface, etc... Removing catalytic converter? Baggage holder considerations?
