I ride a 2003 FXSTB Night Train and love it! It is carbureted with a stage one upgrade. My only complaint is that it seems to be geared too low. I have compared the final drive ratios of the 03 with an 08 and found that the later is geared higher (numerically lower) by about 8%. It was suggested to me that changing the primary ratio will adjust this without having to recalibrate the speedometer. Does anyone have any experience with this type of mod? Where can I get the parts/kit? Does anyone have any comments on this idea?
