Since almost a decade now, retro is the favorite theme of most factory and custom bikes. One more way to look classic or vintage is offered by Bare Knuckle Choppers with this new very nice looking velocity stack conceived to fit the very popular S&S Cycle E & G and also Linkert 4-bolt carburetors (no adaptor plate necessary.) The outer body features an organic shape matching the look of the respective carburetor’s profile.
It is offered with a stack base is made of high quality cast aluminum with raw or polished finish, a machined aluminum cover plate, and your choice of a stainless steel or brass screen. An additional option is a length option. Mounting fasteners to carburetor are hidden and all hardware is included. Made in the USA. Bare Knuckle Choppers.
Will sell well.

How is the incoming air filtered?
Richard. It’s a VELOCITY STACK. Not an air filter. A velocity stack has no filter.
If you want to get all technical, its not a velocity stack, it’s too short and restricted for any real high flow velocity. It’s a carb intake with mesh to keep out big bugs, rocks and denim pant legs.
I like the design, but I would prefer to have a flat face and a laser-cut cover plate in S.S.
It has a simple simplicity and minimalist feel, compared to some CNC billet air filters that are too visually busy and the product of a bored guy doodling on his computer.
Another beautiful piece by a very very talented builder.
Thumbs way up!
This unit is a velocity stack but the face plate and screen defeat the purpose. Velocity stacks may vary in length and diameter. The bell alone will help direct air flow if mounted properly.
Fuji,
You are correct, it is in every way a velocity stack, and we could go into detail about air flow dynamics, resnance, and valve timing, but is just easier to say TerenceTory has no idea what he is talking about. Again.
Dave Blevins, if I bolt it on the flow bench I think that would support my claims. Resonance, “air flow dynamics” and valve timing have little relevance here. It’s all about C.F.M and inlet tract length here.
Velocity stacks need a long enough tract to impart a high velocity flow to increase the fuel mixtures inertia. I think this one is too short to accomplish that effect.
I like the design. It looks very classy
Thanks to Cyril for the great looking press release. Sorry if I did not name the piece correctly, it is simply the term most riders associate with this type of part. Thanks again for the support!
Good stuff Paul ….99.9 % would call it a velocity stack
If one were looking for this
They would search for a VELOCITY STACK ..they will seek well……
enough said….
Paul .
Great looking bike it grabs one attention. Keep up the good work.
You need not apologize for any part of your statement about the bike. You are correct.
Paul. You must understand we are blessed with a blogger possessing a “Doctorate in knowing everything” through the internet, Self appointed
How long must racing/rally stripes be to ensure a laminar flow? 😉
