Stao, they are clearly not sorted setups regardless of the level of modification (compared to one that is, again regardless of mods).
To put such a 'comparison' up serves little purpose and would otherwise mislead people that might not be as aware (i think i've had to say that, what, 3 times now? ).
Earlier! Around 3000-3300rpm-ish where it starts coming up and then sorta kicks another bit and goes up harder.
Could just be the way it is
