Carb Air Screws

[Anonymous]

I am looking for air screws for my 81 GS 750. I can't seem to find a part number on bike bandit or my dealer. Does anyone know the part number/where I can get some?

Should I just try to get some at a salvage yard that arn't stuck?

I can't get them out of my carb, should I just not dunk the body, and spray with carb cleaner really good?

I may have turned one about 3/4 to 1 turn, but the others I couldn't even budge.

What do you guys think?

The air mixture screws?

Do you mean the air mixture screws? If so. Run them all the way down counting the turns on each. Use some penatrating oil if you can't even get them to go down. Then make sure the threads are really clean. They should come out after that. These need to come out before you dip.

If you mean the air screws at the back of the carbs don't bother them. If they won't come out just do the dip with them and blow out with compressed air.

The screw I am talking about is the "air screw" in the carb guide. It's on the top of the carb, engine side, in front of the main part. It could probably be access with just the tank off.

Lets pretend for a second:

Let's say I'm not concerned with emissions, so I plug this screw, sync the carbs, etc. Can I just allow a little more air in to make up for this hole, and not worry about the air screw?

just to make sure I'm talking about the right part...her is apicture



Is this screw for emmisions control, or for regulating richness/leaness....


if I plug this hole, what bad things may happen?

Actually, if you look carefully at the "ther end" of this screw, you'll find the opening is the only one exposed when the carb butterfly is fully closed. I believe it to be impossible to properly balance the carbs without the use of this screw. In the States, where the EPA has made such an issue about emmissions adjustment, these screws may be set in loctite (TM) or may be fused due to reactions of dissimilar metals. I'd try penetrating oil or some heat before I gave up and drilled them out!
