I had to put a 50 cc pump in my 625 Road Demon when I changed cam ( 218/218 to 224/230 @ .050) and to an Edelbrock Air Gap. I also had to open up the pvcr's some as well as open up the low speed air bleeds a little. Suprised me some to have to do all that to get rid of the lean bog and lean stumble at cruise speeds. Also had to play with the secondary vacuum springs some for best results.

I don't think there's any end to the carb tuning one has to do when changes are made in other areas. Mine does have to remain streetable.
