Harley Davidson Bullet 125 - Recent Questions, Troubleshooting & Support
Harley Davidson 2012 Ultra over heated while idling
an engine ,any engine , suffers at idle
there is low coolant circulation , low oil pressures , low charge rates and if it is left idling for any length of time ( more than 10 minutes ) early engine failure can be expected
besides wasting fuel for 60 minutes what is the point of letting it idle
yes the oil is burnt from the overheating and it will need a service now
What does bus er code indicate?
The data bus has bad connections somewhere or a relay or switch is making poor contact. Could be in the
wiring harness or in the ECU, or any one of the other modules. The fact that it gets the indication to the speedo is marginally encouraging.
Try pulling the main fuse under the seat for 30 seconds and plug it back in, see if it clears the code. If it does but the code comes back, either take it to dealer if under warranty or start tracing connections and cleaning tightening them, I'd start at the ECU and work back from there.
