SillyDilly, read this information carefully

The oil you are using has
no history of helping to fix a bad clutch.
Lucas Oil Stabilizer to the tune of 10-15 ounces (really, a half a liter?) is the DEAD WRONG THING TO PUT IN A MOTORCYCLE ENGINE and you have put in way way too much for the 2.5 quarts total sump capacity you are treating.
You are running a heavier than recommended 20w50 oil already and then you are adding a STP look alike to it to drive the viscosity way way UP (which is the wrong way for you to be going) and
you are adding a bunch of plasticizers and friction modifiers to the clutch pack as well, which is death personified for a wet clutch.
Frankly, I would be very surprised if your clutch didn't slip some.....
You need to listen to what the folks say concerning correct oil weights (10w40 or 15w40) and STAY AWAY FROM ADDITIVES/THICKENERS like Lucas or STP.
What works in a car engine DOES NOT WORK IN A WET CLUTCH BIKE
