Kwai 650 sx build needs tuning help
Last year I built a 650sx. Put sbn carb, pipe, intake, exhaust mani, dual plumbing, etc. It run pretty good until the throttle is wide open. It runs the fastest at 3/4 open. When wide open, it bogs a little. Seems like it needs more fuel? Can I adjust the screws or does it need new jets? I have never messed with a carb so some specific details would be greatly appreciated.

Open the high speed screw (closer to the top) about 1/8 turn and see if it gets better.
