Hi Max, The slider needle adjustment allows the carb’s run a little richer than the factory setup, I did it on my bike prior to changing the two main jets as mine had a flat spot around 5k rpm, it solved that problem for me. It’s probably worth trying as it’s a simple modification and if you’re not happy with the results you can easily return it back to factory settings.
The best way to judge your fueling is ok is by the colour of your spark plugs, so you could check the condition of them prior to doing the mod and then checking them after the mod (clean the spark plugs before riding it again after the mod) once you have ridden it for a while.
