Everyone loves velocity stacks! They allow your motor to inhale better and they are sexy as hell!
Fits Honda Shadow VT600 and VT750 and Kawasaki Vulcan VN800:
If you remove the airbox on your Honda Chop with a single carb, the carb will have a hard time creating enough negative vacuum and the air will be far too turbulent in the venturi to pull in a steady flow of fuel from the pilot and main jet, the solution to this issue? Velocity Stacks! This allows the carb throat to be lengthened enough so that the engine can maintain 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 to your engine.
These WILL NOT fit any dual carb model bikes.
You will need to purchase a performance jet kit with your stack to achieve the desired results. The kits you find online will not work with these!
WITH PROPER TUNING, THESE WILL NOT HARM YOUR BIKE, NOR WILL THEY ALLOW ANYTHING HARMFUL INTO YOUR MOTOR!
Please Note: These are not a plug-and-play item. You will need to re-jet and tune your carbs. We also suggest using some loc-tite on the threads. These will not fit dual-carb models
