black or really dark brown is too rich....white or barely light tan is too lean.
a light brown/tan is where you wanna be.

your spark plug is an open book...it will tell you if it's too rich or too lean.

that guy made a lot of sense! i don't know what kind of gas mixture is in my tank now becuse i just got the bike, and i don't know what ''stock'' mixing rate is so to speak but im thingin about going for a 32:1, but check the spark plug first then clean it and se if i can't get the jetting rigth :-D

the majority of us are running 40:1...and there's some running 50:1.

there's nothing wrong with running 32:1 as long as you jet to it, and stick to 32:1....don't ever change ratios unless you jet to those changes....or it could be a very costly mistake.
