new 951 di engine needs to be primed/bleed but HOW?

[Sportster-2001-951C-Stock]

Thank you for this thread!! After my rebuild I've been doing a lot of troubleshooting. Even broke down and bought a CandooPro. It gave me P0166 I believe, which said "engine temperature out of range." Upon doing some research I stumbled on this thread and I too crossed the connectors on the Knock Sensor and Engine Temperature Sensor. What a relief to have my first rebuild actually running correctly. A DI seems like a terrible machine to start out with, but I've learned a lot.

Thanks again.

Yes, it's easy to swap between sensors and connect the wrong connector getting them crossed. Thus, I think the big lesson from this thread is it's best to measure sensor resistance values from the MPEM connector by disconnecting the connector and probing the internal pins based on the electrical schematic diagram to measure the sensor values provided in the service manual.
