For all of you that would like to extend your floorboards outward 1"..."You don't need no stinkin machinist" to accomplish this. There are 3 long screws on each side of the bike that hold the floorboards on. Remove them and take them down to a hardware store like Fastenals and tell them you want the same thing, only 1" longer. Next, on the way home, swing by Lowes and get some shiny new 1" long spacers which slip over your new screws.
Total cost: Less than $15.00. Degree of difficulty is a 1 on a scale of 10. Anybody can do this one. Or, you can support any of several manufacturers which do this for you for about $50.00. Either way you accomplish it will be a noticable improvement over stock floorboards. Unless you are flat tracking your bagger on Saturday nights, I doubt if you will scrape the pavement.
