A two stroke will always want to have some hit, its the nature of the beast. It runs best in a resonant RPM range. When you change deleviery with needles what you primarily do is REDUCE fuel in certain areas, then add it back in others, to surpress or accentuate this.
This thing would be like tuning the bike on a dyno for max power through all throttle positions. Like developing an EFI map.
