The bad gas is most of the issue. After three years carbs will need to be removed cleaned, dipping and soaking will be best. rest of fuel system will need to be flushed and filter replaced.
If the oil says anything abouts Fuel saving or energy efficient on the rating label, it can cause slippage. 20-50 is kinda heavy for your bike also, may be getting some parasitic drag in the clutch, drop down to 10-40 as the heaviest oil you run.
