some issues after carb mod?
 

So this is my setup at the moment.

125 jet
38 jet
snorkel removed
half inch hole in first baffle of stock pipe
air screw 2.5 turns out
second needle clip
13t sprocket

When I am driving at a constant high speed it will hesitate for a second almost like it skipped a tooth on the sprocket(just best way to describe the feeling) also will do it once and awhile on quick takeoff but more during steady road driving.

Would this be a air screw adjustment needed or go bigger than the 125 jet? I put the needle to the third clip and the bike just bogged out and wouldn't start.??

Also I am pretty much at sea level for elevation
