I cant seem to get these carberators dialed in. I just got the bike about a month ago it was not running right so I rebuilt it got it back together. The bike was runnig really rich because the floats were set wrong. I set them to 19 mm now it seams to be running lean. Im running 155 mains and 45 on the pilot with the needle in the middle position. The bike will not idle, and when you let of the throttle it wont idle down right away. I have been playing with this thing for a month now. Any help would be appreciated.
