Reply To: GV650 what year 1st and 2nd generation EFI introduced?
The GV650 EFI started in 2008 2 ECUS (1 normal and other was made in Japan) because in 2008 we also had special aniversary edition red frame GV650 models, also last generation (around 2013-2020) we have DELPHI ECU using Delphi Electronics and revised fuel pumps , and the upcoming GV650 Pro will be DELPHI electronics again.
ALL EFi models are OK , it is just regulator was problematic , so we upgrade to Shingden Regs and Electrosport Stators (like you saw on this website’s shop pages)
Later EFI models (Delphi) use slightly smaller diameter stators , they work OK. But still recommended to change regulators to a beefier one or replace OEM one as soon as they start acting funny. Many fake shingden regulators online, so it is better to go to a local junk yard to find a wrecked Honda (too many models to list).
Hope this helps.
