Thank you for an answer to my home language, wonderful!

Both of these air screws were closed when I took off and rengorde carburetors .... I opened them only 1/2 turn and now 1/2 turn more!
The bike goes like a shot, great engine .... In the lower gears (first) and secund gear so the engine putters a little, when accelerating from idle to 2000 rpm (the same in first gear even if it does not affect and interfere as much, but it's there)

I have checked and sealed all the carburetor page:
Clean, washed and blown all the channels and nozzles.
Checked vacum membranes OK
All vacum hoses OK
Dismantled, checked and cleaned intake rubbers OK
Adjusted balance between throttles OK
Tried to lower the float needles one level (much worse)
Raised needles (as it is now A level remains to raise the needle (do not intend to try)

So? What should I listen for when I screw those screws?
Do I need any instrument, tool?
Or should I just enjoy as is

Thanks for the replies Lucas

Perhaps the mixture screws need to be turned out a bit more. They should be set to achieve the highest idle speed (rpm), then the idle rpm should be reset using the idle speed adjustment knob.

Have you checked the fuel level in each carburetor? It can affect other adjustments, so it should be checked before adjusting the needles or mixture screws.

Fuel level in each carburetor. Check
I will do as you describe with idling.
Many thanks!
You guys are the best!


Enjoy the day, we never know when it will end!

On my 750 twin, the best set point is about two turns out from all the way in on the mixture screws. The stock pilot jets are #45, but you can go up to #50 and it will run better. This advice assumes everything is stock and there are no problems like air leaks.
