Reply To: Issues with 2nd cylinder on 2011 and 2013 bogging
GTRHello 🙂
As you have both EFi bikes , DELPHi system comes early for some countries and later for other countries. I don’t know if you have an older DAEWOO ECU or DELPHI ECU.
In all cases, have you been able to download the service manual from this forum ? There should be a GT250 EFi book which includes GV250 EFi section and follow it’s steps to troubleshoot it’s ECU to get an error code.
If you can get error code out of your ECU, let us know what it says ?
I don’t think the bikes are carby as they stopped in 2008 , but if someone has put carbs on a 2013 bike, i don’t blame them it is much less stressful than fixing an EFi bike. Personally i went the carby route with my GV250 EFi.
However, EFI is okay when it’s working good. While you check for error code, can you yourself or a garage do a quick cylinder compression test ? What is the service history like too ?
It’s a lot of questions I know, but no rush, take your time. You will be going through a process of elimination.
Have a multi meter ready also because even if you have new parts, the service manual has instructions to test the parts for correct OHMS (coils, caps, sensors, etc) or VOLTS (sensors, reg/rec, battery etc,)
You got this!
