1/2 a turn too rich??umm?more turns out of the air screw equals more air so leaner,,less equals richer,,it blocks off air flow as its wound in,and lets more air as its wound out,the burble/blubber on light throttle cruise if you have it is a slightly rich condition,mostly around 3 grand,this can foul plugs if you cruise too much,wont hurt if you ride over 5000 grand all the time which is where these bikes were designed to perform,the float level isnt deadly important as some will tell you or you might think,get is a good as you can though,,inside the fuel bowl is like a washing machine once your riding,,think about whats happening inside the fuel bowl when you accelerate hard through all the gears,and then when you hit the brakes and slow it all up,down a steep hill,,or up one,,then some hard lean angle cornering,,hard left then pitch it over to the right,,the fuel in the bowl is going #$%*ing all over the place,and thats not even a dirt bike?
