Reply To: Gv 650 an st7 650
You can take exhausts from either ST7 or GV650 = But your struggle would be “how to i mount it ?” = Pipes yes , but mufflers will need some creative mounting , if cross-breeding between two bikes.
Aftermarkets = Same thing. If you can mount it creatively there should be no issues. ST7 has lambda sensors , so an old carby GV650 pipes would not work due to missing LAMBDA ports , unless you weld one inside.
Electronics = Hyosung uses 7 ECU’s across their EFi bikes from 250 to 650cc. Very complicated area that needs specific parts you want to change ? Ie. Even igntion coils are different across the years , even their OHM ratings, there is a lot of sensors too that respond to specific ECU’s
Sentec, Edgetek , Mitsubishi, Daewoo, Delphi Malaysia, Delphi USA, Motion, etc. They also sometimes use “certain specific years” of GV650 to use GT250 igniton coils and its lambda sensor but not the ECU , also sometimes they change harness … Ie. a delphi bike , expects delphi sensors on most places with connectors that are not backwards compatible with Sentec Hyosung models. etc. It is complicated, it is best to narrow things down to a very specific part you need.
Don’t always rely on part numbers, they do change parts for the same part number for “updated/revised” versions.
