Vulcan Dictionary


A Short List Of Common Acronyms Used When Describing Classic and Nomad Parts

BUBF
Butt Ugly But Fast These were the original 1500 Vulcans (some say they have "styling issues") made between 1987 and 1995. With their dual carburetors they were more powerful and much faster than the later single carb or FI Vulcans.
Coasters
Flat steel (sometimes chromed) plates designed to fill the hole left in the cylinder head by removal of the Reed Valves.
Coyote Kit
An intake modification that removes the stock left side air cleaner and air tunnel in favor of a single air filter on the right side. Mod is commonly used on carbureted models
EFI
Electronic Fuel Injection introduced on Vulcan 1500 models in 2000
F&S
Fire and Steel aftermarket products offered by Kawasaki
Goat's Belly
Catalytic Converter in many states, an empty metal container in others connecting exhaust header pipes to mufflers.
JOG
Judge's Oil Gear, a steel replacement for the Plastic Oil Gear (POG) created by Judge, a VROC member, that doesn't require engine removal or splitting of the case as does replacement with the Steel Oil Gear (SOG). See http://www.vroc.org/faq/jopg/jopg.html for instructions.
Lowers
Typically clear plastic mounted on fork assembly to funnel air away from the rider and reduce turbulence. Nomads come stock with small lowers.
Marbles
Just ordinary marbles from the toy store used to plug hoses leading to the Coasters. This is a quick fix for backfiring generally noticed on deceleration after exhaust modifications.
Model Designations
The Vulcan A,B & C models (also referred to as BUBF's) are not made any longer. The "A" models were dual carb. The D, E models are the restyled (in 1996) Vulcan "Classics" with single carburetors. "D" has a 4 speed transmission, "E" a 5 speed. The "G" model is the carbed Nomad and L models are fuel injected Nomads. "N" is the Classic FI, "J" is the Drifter and "P" is the Mean Streak.
POG
Plastic Oil Gear used on 1500 engines before 2000 models. Replace with the Kawasaki Steel Oil Gear (SOG, below) or the Judge's gear (above).
Reed Valves
Pollution control devices designed to add fresh air to exhaust gasses as they exit cylinders and enter header pipes. Often removed or bypassed to reduce engine operating temperatures and eliminate backfiring when using aftermarket pipes. They are the "boxes" with hoses connected to the front right of #1 and rear left of #2 cylinders.
Risers
Used to move handle bars back toward rider and upward slightly. Most common are 4x1 risers. Technically 4" up and 1" back but in reality more like 3" up and 2" back due to angles involved
SOG
Steel Oil Gear used on 1500 engines 2000 and later (except Drifters which always had SOG)
Stones
Derogatory term used to describe the Bridgestone tires mounted by the factory on Vulcans & Nomads. Also "Brickstones."
