Harley

Short for Harley Davidson, a marque of American made motorcycle. Manufactured since 1903, the Harley Davidson's most recognizable features are it's 45-degree V Twin engine and distinct exhaust sound.

Harley Davidson dominated the American motorcycle market until the mid-1960's when Honda introduced a line of smaller-displacement less intimidating lightweight bikes. The smaller Japanese bikes could not match the performance of the then ing-of-the-hill Sportster, a bona fide street racer and land-speed record holder and still the best selling middleweight motorcycle in history.

But, the less-intimidating Japanese machines became top-sellers, and changing times hurt Harley Davidson sales.

Harley Davidson was acquired by AMF in the 1960s and quality, along with sales, plummeted. The "AMF Years" almost dealt a death-blow to Harley-Davidson and saddled the motorcycles with a bad reputation which has, unfortunately, been hard to shake, even though the current production bikes have a reputation among motorcyclists as having almost bulletproof reliability.

In the 1980s, Harley was bought back from AMF and completely re-vamped. Quality was back, and customers flocked to dealers, and still do.

redneck engineering

The use of unorthodox methods and tools to build, modify or repair machinery, vehicles, etc, usually with little regard to finesse or technique.

Common tools include: sledgehammers, cutting torches, arc welders, come-alongs, jacks, porta-power kits, large prybars, sawzalls, lengths of pipe and 2 X 4s

So named for the stereotypical redneck who fixes things through brute force and duct tape.
The popular TV shows Monster Garage and Junkyard Wars often feature great masterpieces of redneck engineering

scar merchant

An amateur tattooist or "professional" of bad reputation and low-quality (and low priced) work. Usually an amateur or "a friend who works out of their house", scar merchants, or scratchers are unschooled, unsanitary and generally a big mistake. Going to one is literally buying a scar.
Dude, fuck that guy! Billy Bob is a scar merchant. Go to Tattoo City on Lombard for good work.

Evo

Short for Evolution, a series of Harley-Davidson engines. The "big twin" Evo replaced the Shovelhead in 1984, replaced by the Twin Cam in 1999. The Evo Sportster or XL replaced the Ironhead in 1986 and is still in production, albeit in a rubber-mount format.
