I Hi I'm new to the group. A friend recommends I tried the forums for some help. I have a couple of bikes I'm trying to repair. I need a donor engine for an 05 xt125, so either a Xt or ybr engine. I already have two 05 (I think) engines but they both have slight differences, different connections and amounts of wires coming off the stator plates. So I'm hoping someone out there has a manual or a link for a wiring diagram to help me either source the right engine for a straight swap or perhaps I can get away with swapping the connectors over. Thanks in advance.
