Reply To: [Q] Mirage 250/GV250’selectrical system
Welcome!
We have a few Koreans on the forum, one of them was helping us test many mods on this shop 🙂 , he has a GV300S now. You might meet him where you are by random chance haha.
The early 2005 GV models and ALL OF THEM until 2020, replace these parts right away:
- Regulator. It burns too much. Outsourced part, so Hyosung doesn’t make them
Check these parts (caution)
- Fuel Gauge – Check the sender inside the tank, sometimes it gets sticky
- Fuel Gauge DISPLAY – If the sender is working, check front of bike MPH/KMH gauge to make sure the “fuel level” sensor is 0 (zero) when bike is switched off and if the tank is half full, the needle will be about half full, this confirms everything is working.
- Spark Plug HT Caps = Use NGK ones , because the OEM black ones fail due to heat or sparks also leak! , we use NGK caps like you see in our store and do not worry about it.
- If possible, strip the bike down => Use “ACF50” (only this bottle) => Inside EVERY “connector” you see on the bike, this will help stop connector pins for various electrics from rotting due to harsh winters , rain , oxidizations etc…
(Hyosung started using waterproof connectors on GV300S models, as they were aware of it)
If you want to hide more plugs from weather exposure => Get “SUZUKI HARNESS BOOT” , it hides your plugs/connectors all over the bike (Hyosung uses them , but not enough!!)
Good electric parts
- Stator , if it is black then it is OEM, it lasts a good long time with a good upgraded regulator but you must test it to verify it isn’t “over supplying voltages” or “wires do not have too much resistance”
- Dashboard works well most of the time, as long as it is not cracked or damaged , then no water will ruin the circuits but check for rust under the dashboard!
Regulator is the most important upgrade. And do NOT use Aliexpress versions, they are much worse than Korea made version. Do not worry, older Honda CBR also has regulator problems , even old suzuki bikes used to melt their connectors for regulators!
