My drive is on a slope and I let the bike roll backwards in neutral, then did the same with the clutch pulled in she the gearbox in first gear. Didn't notice any difference so I assume I've got the adjustment right...?
The easiest way to check the adjustment is to run the bike with the clutch in, then slowly let it out. As it reaches the bite point, you should notice a change in the engine note as it just starts to engage the plates.
BTW if you haven't swapped the OEM levers for a set of adjustable aluminium ones, I'd well recommend that so you can ensure the levers are in exactly the right position to be comfortable for you.
Look on YouTube for the Dave Moss videos about how to set the bike ergonomics so it fits you, rather than you fitting the bike
