I decided to adjust the carb needles today because after my pod filter/straight pipes install last month I rejetted to 90/125 but only did 2 1/2 turns out on the needles and was running a little lean. So I did 3 full turns out and took it for a spin for about 15 minutes, got back and removed the plugs and the left one was black and the right one was brown/tan. Is that adjustment just as simple as turning in the left needle a quarter turn to balance it out? I'm curious as to why one needle would need to be 2 3/4 and the other is okay at 3. The bike seems to run good regardless. I'm just wondering if this is a normal thing to have the needles at different turns from one another or should they both be at the same turns out? Thanks for the help.
