(1) Yellow (although a favorite color because of its happy effect on the rider's psyche?) was really inspired by Steve Hawkins and Bruce Launceston, though I've learned that Steve's yellow bike is actually an R100 (his R65 is red). The actual paint-- after going through dozens, including BMW's more recent Sunset Yellow-- is a Mustang color, inappropriately called 'Screaming Yellow'. My previous Airheads were standard BMW colors-- Henna Red (R65LS), Red/Smoke and 'Schwartz'-- so I wouldn't mind having the only yellow R65 in the US, but kinda doubt it!
(2) The fairing is a Givi A755. Its little brother is listed as one of his most recommended products by the Guru of the Airheads Beemer Club. Saw his endorsement AFTER buying mine used (and black) for $120 from a Beemerphile in Florida who took it off his Guzzi.
(3) All initial prep (!) for the headlight ring was done by the previous owner with his upiquitous rattle-can of blue paint. His prepping was apparently better than his painting. Here's one more shot of fairing and headlight ring... The fairing owner had clued a bit of garden hose inside the fairing, which helps minimize gap around the headlight.
