If your butt dyno can't tell the difference a real one will!
i was too lwan on main but too fat on the pilot and nj
changed the needle and upped the main and got better but a big hiccup
went down 2 steps on nj and back to the 6f4 and rides better.

in a couple days i will step back to 140 main and see

my riding is from 5000 to 10000 feet so i have to ride on the lean side of things

if i was going down i would tune on the rich side

i love being able to deccide a change, visualize it, predict the outcome, and be right!
