1981 cb650 air/fuel mixture screw
« on: October 21, 2017, 03:15:11 pm »
Just picked up an 81 cb650. It has an aftermarket exhaust installed and seems to be running lean so I ordered a new jet kit. Does anyone know where the pilot screws are for each carb? Thanks

right in front of the bowls.   From the factory they had limiter caps on them.   By now might have been knocked off.   I leave mine on and grind the tab on the bowl back.   the cap gives you something to get a hold of to turn by hand.
