I raked the frame 4 degrees it improced the handling tons as I tend to travel 75 or so miles an hour the bike has shovel head bags and fairing with late model quick mounts and an fxr tour box. The trans gear has been changed from 32 to 34 drops the rpm 500 and stretches all gears Installing crane mid rangs cams in the 85 inch motor dropped my range to 100 miles and I needed gas. I changed the rear wheel pulley from 70 to 65 european fxsts run this now I can go 160 miles at 75 loaded before I need fuel second gear is a waste of time bike will run 180 kph in third I have no idea of the top speed fairing causes the front end to shake at 100mph but the bike runs 80 mph at 3000 rpm and is real fun to ride You cannot run the 65 rear without running the 34 or changing the belt I have driven this bike to the east and west coasts of canada. If anyone has a problem with the pos. battery coming loose I have the solution stay strong
