These velocity stacks will fit Honda Shadow VLX and VT600 and Honda Shadow VT750 dual carb Motorcycles except pre-1998 VT750 dual carb models. They are made to fit the stock dual carburetors. They may fit other models or brands however we cannot speak to the fitment.
If you remove the air box 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! They allow 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.
Two Dual Carb Velocity Stacks
Two Filtration Screens
6 Stainless Set Screws
Allen Key for Set Screws
You will need to purchase our performance tuning kit with your stacks to achieve the desired results. The kits you find online will not work with these! You can find our in-house performance jet kits HERE.
Please note: These will not fit the VT500, The VT700 or the VT800.
Each stack comes with a metal mesh filter screen to keep out birds, cigarette butts, and small children. These don't even let sand through! The stacks function in all weather. Do not add any other filtration to the v-stacks! Each stack is attached with 3 small size #6-32 set screws. Dual carb stacks come 2 to a set.
To install, put the screen on the carb, then slip the stack on and tighten the set screws. We recommend using a locking agent such as loc-tite to secure the set screws. WITH PROPER TUNING, THESE WILL NOT HARM YOUR BIKE, NOR WILL THEY ALLOW ANYTHING HARMFUL INTO YOUR MOTOR!
These are not a PLUG-N-PLAY item! You will have to tune your bike once you install these stacks. There's lots of good info on how to tune on our Support Page and YouTube videos explain the process pretty well. Our YouTube channel is TJBRUTALCUSTOMS.
