All I can say is if it is lean, it will be asmatic, won't pick up speed easily, breathe hard, be hot. Easy to tell if lean.
If rich, it will stumble, sputter if real bad, but run cooler. It is hard to tell if slightly rich unless you change to a leaner setting and you get an improvement.
Now perfect, it will just explode in power, no hesitations, no fuss. You will know if you got it right. This is why it is good to have a play around with a few jet sizes. The needle will have the biggest effect on how your bike runs.
The pilot circuit corresponds to 0 - 1/4 throttle, needle 1/4 - 3/4, main 3/4 to full open. Ues these throttle settings as a guide to find out what you need to change.
Only change one thing at a time as each circuit is effected by them all.
With your jetting, I would leave the needle where it is when you go to Mexico, the pilot and main jets are very easy to change out when you get there. Just go with the 48pilot and 168 main. You might find the 165 is good enough for you depending on how modded your bike is. If you don't have an adjustable fuel screw, get one. They make pilot circuit tuning simple, and perfect pilot circuit will crispen up throttle response.
