Hi. Won't be home for a few days and want to order Apex adjustable clip ons. I don't know which size to get. I have an 04 v11. I'm not sure of model as it was one of the last 04 built. Think guzzi kinda pieced it together with what was on the shelves. I bought it brand new in 2009 as a left over from rose farm. It has black marzuchi ? Forks. Not Olin's. I can email a knowledgable person some pics. Thanks in advance-AL
