The air/fuel screws won't have any effect on the top end. That would be governed by the main jet. Did you install the Boyseen Reeds? If this is a new addition it could be the problem. Another thing could be the fuel level in the carburetor bowl. When you tore down the carb it is possible the float got out of adjustment. You could drop the bowl and see if the fuel level is correct. If not, bend the tab on the float to adjust it.

There is a small knurled knob to the rear base at centre of carbies, this turns a worm screw, actuating a bar for all 4 carbs. The site below provides an exploded view and name of carby parts.
Here's a tip...if the knurled knob (designed to turn by hand) is too hard to turn, a multi facet (not hexagon facet) socket or ring spanner is far easier than pliers or grippers.

SOURCE: How many times do I
I am assuming you are talking about the idle of the bike, which should be 1400-1600 RPMs. If you are talking about the air fuel screw it should be 1 3/4 turns out. Make sure not to tighten it to tight as you can damage the needle. I hope this answers your question. Thank you.

i take it the carb isnt the original one? well you can still set it up for the bike take the carb of and remove the bottom and check the floats there shouldnt be petrol flowing out of the overflow pipe when the bike is running when you have done that take the top of the carb apart and remove the needle valve from the top its connected to the throttle cable blow down the jets to clean them out re assemble the carb
there is 2 screws on the side of the carb 1 is the air screw the other is the tick over turn them both in till they are tight then turn them 2 turns out
when you start the bike it might run fast at idle or backfire if it does adjust the top screw for tick over(idle) the bottom screw for running better
hope this helps
