I recently got my 1981 Suzuki GS450L running. It has CV carbs with aftermarket Air Pods (bike did not come with the factory air box). I put washers in the pods to restrict the airflow to try and recreate the airflow of the air box. The bike bogs when I set off, and it idles high when its stopped or the clutch is disengaged. Any advise would be helpful. Thank You!
