My brother just picked up his 08 fatboy yesterday. It's got a few changes that I noticed. first thing I saw is it has a fuel range read out on the odometer. It's supposed to tell you how many miles you have left before your empty. Then just for the heck of it I pulled up the code setting and it has an extra letter (b), I assume that's for the antilock brake system on some models. His doesn't have them cause when I checked it said no rsp. He also told me that the dealer told him that they did away with the cam chain tensioner and replaced it with some kind of hydraulic tensioner??????:dknow not sure on that one, maybe someone else has some input about it.
