Lightbar and handlebar questions

[indianapilot]

I've only had my '04 Nomad for a few months and hope to get help with a few questions. The Kaw lightbar beams are still too high after adjusting as much as possible. Can a thin piece of foam be stuck to the sealed beam, forcing it too shine lower. Any other ideas? Also, I need to retighten the screws holding down the risers. Can this be done without removing the clutch and brake cylinders and throttle linkage? Thanks in advance for your help.
