If you remove the airbox components on a Honda Shadow with dual carbs, the carbs will have a hard time creating enough negative vacuum to pull in a steady flow of fuel from the pilot and main jet. The solution to this issue? Velocity Stacks! This allows the carburetors venturi to be lengthened enough so that the engine can maintain constant vacuum beyond the slide of each carb, as well as allow the air turbulence to be reduced. resulting in a much smoother delivery of air and fuel emulsification to your engine.

Fits: 

• Honda Shadow VT1100 Models 1997 - 2007
• May fit earlier years but we are unable to guarantee fit at this time. 

Includes: 

• Two Dual Carb Velocity Stacks for Honda Shadow VT1100
• Two Stainless Filtration Screens
• 6 Stainless #6-32 Set Screws

Each stack comes with a stainless filtration screen to keep out birds, cigarette butts and small children. Each stack is attached with 3 small set screws. Dual carb stacks come 2 stacks to a set. 

When installing these you will need to move some of the wiring harness, cables and wires out of the way, Be patient and take your time! 

These are NOT a PLUG-N-PLAY item. You will have to tune your bike once you install these stacks. 

THINGS YOU'll ALSO NEED:
