My 78 FLH comes stock with 51 tooth rear sprocket which produces top speed of about 85 mph. By reducing to a 48 tooth rear I gain about 400 rpm and top speed of about 105 mph. A little less acceleration but I compensated with S&S carb which draws more gas and increases power a little. Leave your baffles in your exhaust if you go this route.
