BD250-7 X-Pro Falcon 250 MT05.2 ECU

rd-china-moto · 07-10-2023, 11:54 AM

I bought a BD250-7 from a person. Its now seems to have developed a issue where it just shuts down while riding randomly and I now feel its the ECU failing or rebooting itself??

The ECU is a MT05.2 ... I have redone every electrical connection on the entire bike to no avail.

What I see is the tac signal on the speedometer drop out and the bike cuts out ... if I pull in the clutch and hit the starter it fires right back up most of the time only to do it over and over. I have been trying to source a replacement ECU for this bike and so far have had no luck. The bike is a 2021 X-Pro Falcon 250 EFI ... BD250-7 model...

Any help is appreciated.

Welcome, broheim. I'm pretty new here, too, but my suggestion is to take a look at your main ground strap if you haven't already. I like to clean them with some fine sand paper, then hit them with a light coating of WD40.

Good luck. Since it's an EFI bike, I've read some issues with the map sensor, I believe.

The overall power on the rest of the bike stays up while this is happening... SpeedO shows speed still but that signal comes up direct from the wheel... If there is a ground for the ECU I will try to find that and also clean it..
