Gen-Mar makes a riser kit for the Bandit that raises the bars about 1" and brings them back about 1 and 3/8". It includes a new brake hose which is needed, but the clutch hose can be repositioned and the cables still reach.
I added a 1" spacer under the Gen-Mars and got longer bolts at the local hardware store -- then I needed to reposition the choke and throttle cables to a position BEHIND the forks in order to have proper slack when turning the handlebars. No big deal, just some monkeying around.
I used a plumbing adapter (bronze, but painted black) as the spacer after filing the ends flat for best contact with the triple tree and the Gen-Mars. The comfort is increased a lot and as I use the bike for a touring platform it was worth the time, expense and trouble.
