Harley Deuce risers (mostly knockoffs) are 5.5" tall (vice the stock ones at 3 1/8") work great, but you have to 1) grind the domes off the bottoms to flat, 2) drill out the riser holes on the tree (or use the conversion bolts above), and 3) reroute the throttle cables inside the tree.
Note that the Interstate throttle cable mounts at the bars come straight out the center, and not from the bottom like tourers and standards. This gives interstates just a bit more throttle cable slack.
Standard.
