I don't want to argue / i am havving lotsa fun doing it
/, but the pilot jet rarely needs to be touched, unless You do something drastic.
Like a rule, if the bike is idling, you blip the trottle and the bike revvs up and after that dies- RICH. If You revv the bike and let go, but the bike is still "hanging' at 2K rpm - lean. Play with the idle screw.
If You are trying to accelerate and the bike just makes noise, but doesn't go anywhere /flat spot/- usually LEAN.
The best part- You spent couple of bucks and now You are havving so much fun !
