I have a Kymco Xciting 500i ABS, and sometimes it struggles with startup, it got a bit better after I did all the services (oil, filters, spark plug, even transmission fluid) but sometimes it just fails to startup, it shows for a couple of seconds a B05-41 code on the tiny digital display before resetting itself. Clock gets reset to 12:00. After that I am usually able to start it anyway after a couple of more tries.
I cannot find the meaning of that code anywhere, so I don’t even know how do diagnose what’s wrong. Anyone ever experienced anything like that?
