GS1000L carb help

[igorok22]

Hi all, I am new to bikes, and I got myself a 1980 Suzuki GS1000L, 19400mi on it. Its all stock, no mods. Cleaned carbs, seems to run well when idling, but when I give it gas it goes to about 4000rpm and dies. I adjusted fuel screws to 1.5 turns, 2 turns, 2.5, 3 turns.... same problem. May it be leaky manifold boots? Any help appreciated, Thanks

Make sure there's fuel flowing to the carbs. It sounds like it's running out of gas. How did you clean the carbs?

Have you done any research yet?

Carbs are full of gas, it idles good. Soaked all internal parts in carb cleaner for three days. Cleaned all holes in carbs body. it only chokes when I give it gas.

Got a air filter element in there? Check for leaks from there to carbs inlets- any leaks will cause it to fall flat on its face above 3000 rpm.
And get some new handlebars- those look painful!

Shouldn't bike still run with airbox off? why would it matter if theres a leak in airbox boots?

No mods... except for the highway bars, hand grips, saddle bags, and luggage rack, right? I'm just joshing you... I have the 850 version of your bike and it's fantastic!

It might idle kinda sorta okay with the airbox off, but it will never run right with the airbox off, unless you do some pretty mean jetting.

These engines are very sensitive to air leaks. So if you have the stock jetting, you have to properly oil your air filter, seal up the airbox, replace the o-rings under the intake manifold boots, and probably buy new intake manifold and airbox boots if the existing ones are the originals.
