Anytime I'm in working around hot things that could burn my hands, I wear Mechanix gloves - they have a combination of foam and spandex that will protect you from searing the skin off your hands.

I was thinking that as I wrote it. But they are fantastic gloves! :)

imfree, there is a $40 Honda tool, part number 07MMA-MT3010B that adjusts them:

Honda 07MMA-MT3010B wrench

If you look at the end, it has a "D" shape opening:

Some people have made a replacement tool using a small piece of pipe, and gently hammering one side in to make the "D" shape. I have read also where people were successful just using a small socket and extension.

The screws That I am talking about are on the bottom of the carbs with 1-1/2 inchs between them and the engine and require a flat blade screw driver to turn.When I rebuilt the carbs I replaced these needle screws and turned them out 3 turns as per the book,Now I need to fine tune them.I think my carbs are to rich.

It is very difficult to adjust the idle mixture screws on the GL1100 as they are in a vertical position with only an inch or so clearance to the engine case and they are blocked by the intake tubes so you cant get a hand near them. I have tried various automotive carb tools but they didn’t work so I made my own. It consists of a closed screwdriver tip (custom machined to fit the mixture screw) so it will stay on the screw head, a bearing so as to eliminate friction, a length of speedometer cable and a handle (an old screwdriver). This set up works well and with marks on the driver tip and the friction free turning capability I can quickly and accurately adjust all four carbs. I also made some tools for the idle stop screws to simplify synchronizing the carbs.

i had tried one of those tools but with the open angle it would not fit square on the adjustment screw and on wings with stiff / stuck screws the potential to damage the slot or worse brake it off is why i designed and built my own. it has a closed angle which allows for the driver to align correctly with the screw and the un-housed cable drive helps prevent over torquing stubborn screws.

thanks ! this tool has made adjusting the pilot screws a breeze. the speedometer cable is swadged to the tip and handle. if you have access to a lathe and mill this is a very simple project. i machined the tip out of steel to fit the pilot screws and pressed an aluminum collar around it to keep it centered on the screw. the rest was sized to fit a bearing that was handy then center drilled for a snug fit on the cable and then just swadge the cable in place. same for the adjusting handle. the housing ring again was machined to fit the bearing and welded to an old screwdriver for a handle.

I have found a tool that works incredibly well for carburetor adjustment, I think I bought it from amazon It was made by Pit Posse. I am sorry to say it is not made in america, our friends in Taiwan are producing it, The box it comes in reads "Angle Drive For Moto". The description is "90 Degree Offset Carburetor Adjusting Set" Part # PP2590. This tool is a little tricky to use, but once you get the hang of it, you won't believe how easy it is to make the Idle Screw adjustment on your motorcycle. I would love to see an american version of this tool produced.
I hope I can get away with a little plug for the producers of this tool. Here is a link:
http://pitposse.com/po90deofcaad.html
I know these sell for less than $79 I believe it sells for $59 on Amazon.
A little bit of searching on the internet will land you a very handy tool.
