In response to this thread I have a 2023 KPX 250 with 25 miles on the clock and looking at this EFI manual shown on this thread my injection does not resemble this configuration. I am aware of the re-mapping of the cdi which I will take on at a different time to fix hesitation in throttle. I do not see any Idle gulp adjustment screw and have looked everywhere. The issue is: even though it idles ok it sounds almost like pinging/ engine ping/knock on immediate acceleration all gears. If it is too lean I cannot see where there is any adjustment screw. I am using 90 Rev octane from the get go. I thought it was a rattle and have tightened , zip tied everything under the sun.
I have checked all clamps and checked for air leaks.
