I just want to make sure I'm gonna be messing with the correct ones. When you guys say to run the air screws in, then run them out three turns, which screws are these. My bike is still running a little rich, and I want to see if this helps.

Thanks


btw, pics would be a bonus [img]i/expressions/face-icon-small-wink.gif[/img]

 

The air screws are in front of the float bowls of each carb. under each carb there is 2 holes, one of the holes does not stick down as far as the other, inside this hole is where the screw is located.

If you figure out an easy way to adjust these without taking the carbs off please let me know. I have heard of someone on here welding a "T" to the screws for easy adjustment but that would mean I would have to take the carbs off when I'm not even sure if they need adjusting.

 

motion pro makes a tool for about $12 which will allow adjustment with a steady hand ,use a mirror to double check your work.

 

Use a small driver (long style) bit that is for a cordless drill. It is tough to get at but you can do it. By the way, being ahead of the needle (towards motor) make this a fuel screw not an air screw. More turns out = more fuel.

 

What is the max turns out you can go?

 

Good point Murph660R! But I think more technically it's called the air/fuel mixture screw.

I tried using a screw bit but can't get my hand positioned right to turn it.

sandjunkie, I believe after 4 turns out there is no increase in fuel.

 

You are right 2fiftyX. I hear it called an air screw all the time which can be misleading. I had a tough time adjusting them without removing the carbs but I did do it. I used my fingertip on the bottom of the bit to hold it and a small wrench to turn it while counting the flats. Not wanting to remove the carbs again motivated me enough to get it done.

 

thanks guys, are they philips or flat head screws btw?

 

standard "flat head" screws.
