I think it's worth noting that "easy" or "hard" are not one thing. What we can do easily or what we struggle with depends on our experience and aptitude.
At least, that's what I tell myself about my inability to do good wheelies.

I'm good at that and too old to start fiddling with something that does not need fiddled with, in most cases and for most guys. Expertly rebuilt and tuned carbs means far more to most than exact cam degreeing.

Please see R&D Platform thread. I think I explained what happens and what numbers there.
I agree 100% with this, which is a source of considerable stress for me.
But I don't think this is the whole story, because at 4250 RPM, the engine is making 53 ft-lbs, which then drops to 46 at 5000, and back to 52 at 5500. I think that this means there has to be some kind of resonance issue like reversion happening.At the low/midrange where the dip occurs there's not enough port velocity to fully fill the cyl.
