    Default Bike running lean

    I don't have Glenn's A/F screw, I have the other one that was sold that you can use an open end wrench to adjust it. Question is, my bike is running lean, you can smell it and runs like crap. Which direction do I turn the screw to make it richer? Clockwise or counter clockwise? Thanks for the help.

    From what I gathered on here and the manual, turn it until it's seats. Then back it out 1 5/8 turns. Start your adjustments from that point. Out is rich and in is lean. Only adjust in 1/8 encriments. That's what I have gathered from the guys here.

    if its like all the carbs I ever built(literaly thousands) you should go clockwise to make it richer as thats an air screw and the further out you go the leaner the mixture. I will say I havent messed with the carb on my bike since I got it.

    Is that by using righty tighty, lefty loosey . Maybe it's just me but i have a hard time with turn it until it seats. I assume that means to turn it clockwise and tighten it?

    Its a fuel screw, Not an air screw.

    What do you smell, raw fuel? If so, your rich and need to turn in (clockwise). If your plugs are more to the white side, then your lean and need to turn it out (counterclockwise) .
