Here is a factory wiring diagram for the Honda XR650R. It is specifically from a 2000 model, but they were mostly the same. Please not that this is only a U-Type XR650R which was the street legal model available in Australia and select other parts of the globe.
The Honda XR650R is a dry sump motor just like all the other Honda XR’s. The majority of oil is stored in the oil tank above the motor. By having the oil tank high up it means that the oil pressure pump will always have a good stream of oil from which to pull. Oil is pulled (so to speak) by the pressure pump down through the oil strainer on the front of the frame. Oil is circulated through the top end of the motor, across the crank, and into the transmission. It is then sucked up out of the sump through a screen by the scavenging pump and pushed back up into the tank in the frame through the plumbing on the right side of the frame. It’s a very simple system which is reliable and simple to monitor.
