As per simon says,
i wanted to add by saying flactuating idles may also mean that it’s time to check for these too:
- Airbox Sensors (air sensors) are not clogged up?)
- Air leak around the intake parts of the bike ? causing surging revs and dipping revs etc.. (like a yo-yo)
- Lambda sensor at the exhaust, give it a good clean and retry
- If you are near shops for cars or bikes , please by this product below , put “ALL OF IT” inside the tank, (and use maybe half a tank or normal fuel to mix), now this liquid will travel all over your fuel system and try to clean anything that’s clogging up (funny revs can also be a sign the bike is “trying” to hunt for fuel to make stable revs or it revs higher from ECU to stop it stalling)
- ISCV (idle speed control valve) – Common Hyosung thing, sometimes they work for years without issues , but check it , it is near the airbox. it is electronic with a big plug usually (but Hyosung may have shrunk it)
- Do not use Redex. Only this product is my recommendation.
