GL1100 Idle mixture setting

Postby ax7el34 » Tue Sep 01, 2009 8:04 am



Do you have a good setting for the idle mixture screws (pilot screw) on the 1981 GL1100? Haynes goes through an elaborate synchronization process of opening up all four screws then turning them in based on rpm loss. Also, describe position of mixture screw on the carburetor(s). I believe on the bottom on carb pointed straight down, up front toward the intake tube. Brass I believe.

when you say 2 1/2 to 3 turns out this is full rotations of the screw correct. Of course the 2 1/2 should give it away but I want to be sure.

Thanks :mrgreen:

I turned mine out two full turns and the bike runs fine. I think it depends on your bike. Just turn them all out the same until it runs well. Yes they are the small brass screws on the bottom of the carbs. Only three of the carbs have them. Just be very careful when screwing these in that you do not screw them in too far or you will have big problems :(

Hi, First time on here, I have just purchased my 1980 GL1100, been standing since 1996, and not run the engine since before then, so have had to rebuild carbs as they were solid. Anyway, the pilot screw adjustment I am going through that at the moment, so I wish you luck as I hope you do me. On a previouse answer someone said there are only three screws :roll: well sorry to say all carbs have them totall of four, I started as the Hanynes Manual states, It did not run, so I would start at two full turns out then fine adjustment on the bike, the tool I use for this I got off of Ebay £17.00 + p&p well worth it, just type in pilot screw adjustment tool. or

Hope you were talking about the tool, if so very useful. I have know spent a few hours on the setting of the pilot screws and not going well, once I get a reasonable tick over 1000rpm+, any lower it only fires on Number four cylinder, but at higher rpm it fires on all four, HELP. :cry:

I recently set my pilot screws at 2.0 turns out. The bike is running great. I started by adjusting all four at 2.5 turns out. I then adjusted one carb to 2.0 turns out and got a slight rpm increase. I then adjusted all four to 2.0 turns out.

I am under the belief that the '80 & '81 are 1-1/4 turns out for the idle mixture screws.
Te '82 & '83 are more like 2 -3/4 turns I thought....?
Mine on the '80 are at 1-1/4 and are nearly perfect....
