      Good morning Community

       

      Any way to reduce the idle Mechanically? I know its managed electronically thats why I am asking.

      She idles at 2000 when cold, which is normal, but warm she sits at 1500 revs which I find, it feels and sounds, too high

       

      Thanks

      Starting up = 15-2000 revs
      Warm / hot = 15-1800 revs

      This is normal. It’s been the case since 2001 for Hyosung GV125 (Carby) & GV125-S EFi to idle at 1500- ish when hot as per manual.

      So you’re Okay there 🙂
