I put on Bubs pipes this winter and I love them. They pop on decel so I removed the AI and the snorkel. That seemed to work as soon as I took off but after about 20 minute ride the pops are back but are to a lesser extent. Everyone says turn "air Screws" out to 3 1/2 but I hate messing with carbs and I really do not know which ones the "air Screws" are. Im sure its a dumb question but I really don't want to get into carb trouble. Anybody have a link to a picture of them or something. Do I need a special screwdriver or anything?
