Had honda jet my 2002 honda shadow sabre 1100. Went stage 3 because there were k&n filter pods directly on carbs and breathers. And 2 to 1 v&h exhaust that when it goes to one just has a turn down tip. Anyways while jetting. They said diaphragms are ripped. Replaced them. Bike ran like **** after. Brought it back. Now they are saying it's not getting enough air. Want to just put velocity stacks on but can find any made for the bike. Does anyone know the mm size for the carbs so I can find some that will work. Or any idea how to get more air. Panty hose and a hose clamp on the carbs maybe?
