Title: Velocity stacks
Post by wombat on 02/27/12 at 10:07:49

I have shop that made custom velocity stacks for one of my other bikes and was wondering if you guys would like them for your LS650s. They are made from aluminum with a knurled ring, three set screws to hold it in place, and a fine-mesh brass screen. The workmanship is excellent. He has blanks that would work for the Mikuni 40ss carbs with its 57mm mouth, that are about 44 mm from base to outer edge, and 76 mm in diameter. His price for one is about $40 (plus shipping), which is cheap. If we get a few orders together he might bring the price down even more. Let me know by email.
Also, let me know if these photos show up, I'm new at pasting them on a post ;-)

Wombat, have you installed one of these on the Savage? I'd be interested in knowing if your jetting would go all wonky again and you'd have to start tuning again...

whenever airflow is changed fuel needs to be adjusted also

Those are beautiful; really well made, but Yeah, I would assume no mater what carb or set up you had, you'd have to re-jet with any kind of velocity stack. It basically creates absolutely uninterrupted airflow with no back pressure at all - even more open than any kind of cone filter...

No, I haven't installed one yet. And yes, you'd have to fool with the jetting

I would imagine that a K&N slab filter is less restrictive, so the only benefit would be looks.

Ooooooh, shiny! I'd be interested if I wasn't getting a new carb setup soon. Does yer guy have anything that'll fit a 36mm Mikuni?

Ya I'm in for one. Once that airbox is gone, yanking the carb is cake. How much extra velocity is this going to give me, ha ha.

That was my first thought too...is there one for the 36/38mm VM carb ?

The filter side is 62mm

By the way, very nice photo's ;)

Is that thing gonna clean the air?

Done my share of jet tuning so yeah I can do that. My guess is this would keeps leaves out and that's about it.
It is incredibly cool lookin' tho'
rt now I've got a K&N drop in filter

I'd be interested in what performance one gets after someone installs this on a savage.
Any thoughts on what this is going to do to your engine since the screen basically keeps bugs out?

What it's going to do will depend on where, when, and how you ride it. Yes it will keep the bugs and leaves out, but should otherwise give you unrestricted airflow. If you ride in the rain, or wet, or dirt/fine dust/road salt (A serious condition up here in the great white North...) those fine particles will get sucked right in.
I can't speak directly about this particular Velocity Stack - I'm just talking generally. Most usually come with some sort of screen, like this one. The finer the screen, the more protection it will offer, but it's NOT a filter.
A lot of guys who use them, will keep a cone filter on hand for wet/dirty conditions and use the stack on clean, dry days. You just need to have a cone filter with REALLY good air flow so that the jetting wouldn't need to be changed.
With the Savage, it should be an easy 5 minute swap every time, (I'm guessing...) so it wouldn't be impractical to have both, and this looks like a very nicely made unit for a very good price...

6" velocity stock on Edelbrock carb in this photo. I use a microscreen filter that fits over the outside of the intake...will take a photo of that later and post it here

HEY LANCER, THAT LOOKS AMAZING!
Can you tell us more about it; how it works for you, and why you have it set up that way? Why is it so long? Does that help with turbulence?
I'm sure you've posted this info elsewhere, so just some links, or tell us where to look for it would be helpful.
Cheers!

The longer the tunnel the more the air flow is straightened out before it enters the engine, and should improve air velocity as a result.
More velocity = more power & responsiveness.

I considered putting one on my MK2, as Amal makes one for it, but decided to stick with my K&N. It's a personal preference but I feel I'm choosing cleaner air over faster air. Is that not a correct assessment?

Hey wombat are you still getting those velocity stacks cuz id really be down to get one from your guy making those things i cant pm cuz i need to reach 10 posts >:( since im just signed up for the site lol

It is difficult to judge from the pictures, but I would guess the wire mesh essentially blocks off about half of the area of the stack, and would thus restrict the airflow. Also, the round wires from which the mesh is made are not streamlined, so the flow around and downstream from the wires would be turbulent.
