When my young bloke was 6 or 7 he had a KX80 and I fitted a Easy Pull clutch.
While it did ease some of the load it did also reduce some of the movement of the actuating arm meaning I had to have zero slack in the cable to get the clutch to function, having zero slack puts plate slip at risk.
Have you had a look at your clutch basket ?
They wear low points on the outer basket were the plates ride so when you pull on the leaver the plates must ride up onto the high points to separate.
Smoothing out the high points will make the clutch action easier and smoother, it is free to do and I would give it a try if I was in your position.

Live life on the edge you will see more that way.
Ridding a motorcycle keeps things in balance.
At the end of each trail and at the end of each day history is made.
