Back in the 90's my wife & I went to our first Airhead Death Valley Rally.
Gary Hanson had a big jar full of dozens of "odd-ball" motorcycle parts and pieces.
Everyone was challenged to inspect the jar and guess how many of the parts were original BMW Airhead parts.
Of all the dozens of veteran Airheads and riders, my Wife was the one who won the challenge and had the proper answer. Beginners luck I'd say (?) ....... I won the exhaust nut wrench!
The "Expert" parts identifier and a pal on her old Honda 350 - 4.
I made her ride that little vibrating monster for a 1000 miles to Death Valley and back. She still hasn't forgiven me.
