To adjust, you need a deep, 13mm socket to get to the locknut. If you don’t have one (we didn’t at the time), you can use a 10mm socket to back out the adjustment bolt if it isn’t too tight. If everything is stock on the bike, adjusting the bolt all the way to the locknut isn’t going to cause any contact between fork and radiator. We don’t, however, suggest removing the locknut or the bolt altogether. You get a little bit more turning radius, but it puts the fork tube dangerously close to the radiator. In a tip-over when things are flexing, you want some breathing room.
