Does fuel's Ron affect idling stability???

[zirconxi_imp]

Hi All, interesting thing I encounter today, I ran my CB till the tank almost empty and pump in 12Liter of fresh RON97 fuel. I believe the '13 CB tank is only 13L.. Previously the bike was running on RON95 fuel. Right after I refuel, my bike started to run a bit high on idle on a warm engine (about 1250rpm). Then I did a throttle position reset and now the idle is fluctuating between 1000 and 1100, jumping up and down quite actively. Before this while running on ron95, the idle was stable at 1050. After the bike cold down I wash the bike and after washing, the idle become stable at 1050 again.

Is the ECU learning to adjust to new fuel? or I ran the tank till too low and fuel pump is hurt? or the mysterious idle unstable issue?

Does our CB have any knock sensor that will adjust Ignition Timing based on knock sensor??
