This time we made something easier than all the other projects we previously did! Therefore, we can upload videos like this more often. Please leave your comments below if you like us to keep doing that! The extreme constructions though will continue as usual.
Love the variety of projects, so glad to see a mix of depths. Videoing projects takes more planning for the shot sequences, with your edits in-mind as well. Even a short video can take a day or three, so I can imagine your longer works take quite a bit of time and effort. Your edits, showing one piece, then quick slices of the "then we did two more" and highlights of the trickier technical work, are *golden*. I so enjoy what's in front and behind the camera that I have to comment in thanks and appreciation. The project selections are all something I'd like and I can imagine how much fun that bike is.
When the video is without music, it is better and more beautiful. I love hearing instrument sounds while I'm working. We hope the following videos are without the music sounds. You are a wonderful creator
A tip for dividing into 3 on the lathe (for the tapping & drilling ) is to use a suitable length of rod between the lathe bed and the side of a jaw on the chuck... 3 jaws = 3 divisions !! Works great & saves the time of setting up the dividing head .... 😎👍☘
Very nice work! One thing I want to say: it's nice that you get the outside of the velocity stack shiny, but do not polish the inside. It doesn't have to be rough, the ideal is something simular to glass marble blaster finish. If the inside is shiny as well, gas might form droplets and it is not good. Altought the velocity stack is before carburetor, it is good practise to keep it somewhat rough.
Wayne and Thomas you guys are both right, but the velocity stack doesn't need to be facing forward? For more air to push through the velocity stack to the engine, this method works best in EFI motors , i havent see it before facing backwards... Please correct me if i am wrong, id love to learn some things.
@@@dimitrismanolakis3344; The velocity stacks I bought for my KZ faced backwards. Given the position, I still used a foam/open cellulose breather cover. You'd be surprised at the amount of crap that can be picked-up in the wind vortex.
While these are beautiful they will slow the volume of air to the carbs due to the small filter surface area. Also the filters will plug up much quicker.
Why would it slow the volume of air into the carbs? The diameter of the intake has been kept constant with the velocity stack, and it seems as if that would have a greater impact on air flow. I do understand the second statement that they will become dirty quicker and in turn there is a possibility it will take in less air, but the first statement doesn’t make sense to me. It’s been my understanding that the design of air filters is such so that they last longer, but I’ve never heard of increased surface area resulting in better air flow to carbs. Are you a mechanic? Would you mind explaining your first statement in detail as it intuitively does not make sense.
using the standard air filter, there's a very large surface area thru which to draw the air. by using these tiny filters there's a much smaller area for the air to get sucked thru...…………… makes sense if you have more than two brain cells to rub together. actually, literally intuitively makes sense.
A point. i always think (and I'm sure others do) that Calling someone stupid and swearing in a public forum tells everyone you are an ill-mannered bigot and idiot who has not had an education, acts like a child and has no manners. I sincerely hope you don't kiss your mother with that mouth!
It's cool to watch you make things out of metal. It doesn't really make a difference what it is. I like your constructions because they are made with quality and longevity in mind.
You should get back the airbox with its proper filter on. Otherwise your engine will eat dirt and just mangle itself. Those stacks are just aesthetic,but have no real purpose : they are facing the back,are in an angle and too shortto do something useful air speed wise. They just create a turbulent airflow ,contrary to the stock airbox. They also lean out the mixture,wich is not good.
Plus those disks of mesh are only held against the carb. inlet with hand pressure as the stacks are nipped with grub screws.There seems a real possibility of them getting pulled into the carbs. If the short bits of steel wire in the weave separate that'll change things in the engine.
Those look great but cutting the filter area down by 90% will create too much of a restriction at high rpms and the engine will run rich and lose power. You need to use a more porous filter to maintain the peak power of the engine but that will reduce the engine life.
@@konradhryniewicki7956 how true. I once had to repair a Kawasaki that had part of a sweet wrapper stuck in the carb(no air filter) the rest of it got blown out of the exhaust!
If you switch from the original airbox to a pod filter you will get more air and run lean. I would equate these much more to pod filters than the default airbox regarding airflow, but it's hard to say for sure without measuring the exhaust or running the bike more. Some kinda rejetting is surely needed.
Oh my God... would love one of these on my 1976 R100S... another idea would be to make a couple of aluminium admission pipes to replace the original plastic ones but that mlight not be so simple considering their bent shape... Fantastic job
Угу. ЦПГ будет на этой бэхе каждый месяц менять. Зато красотиШШа - аж капец. Но вообще - мужичок рукастый, надо признать. И обвес у его гаражика ничего так.
interesting , liked the way you made those filters need some velocity stacks for a project in the future , i was thinking on spinning them out of straight aluminium pipe but i dont know if i can do it good enough with the tools i have i think the stacks are a little in the way with where you have the footpegs mounted and you might need to support the carbs at the rear or solid mount them to the cilinders , as they might actually fall off under driving
@@kristoferjonsson3362 Its a constant depression carb, the engine does the metering work which creates a depression in the carb and the piston "floats" to the right level of downdraught the engine requires, its basically the same as a Stromberg or SU CD carb and they do tend to like a bit of draw on the filter side which makes the engine pull a little more. Its why classic Mini owners upon putting pancake open air filters on their twin SU's found a power drop compared to the stock air filter. I fitted a pancake to my SU and my car was very bleugh until I put the original filter back on.
@@dodgydruid you are absolutely..... correct. also, the airbox will take out the pulsation of the suck, no suck from each cylinder and create a constant flow. besides that, it helps keep water out of the engine, acting as a catch. even the random puddle or rogue sprinkler on a sunny day.
I think it’s just ridiculous, keeps water out of the engine. What are you doing surfing with the bike. It’s an airhead! It’s like remixing songs, people are always doing things that they shouldn’t do. I’m down for modifications but some people go overboard. Perfect example!
I love the bike. My grandfather always wanted a Boxer BMW with a sidecart but he could never buy one because the were'nt sold in the GDR. When i have the money i want to build one, but living in Germany the Regulations area pain in the ass. I have had the exact same pictures in my had like the one you built.
If you want to run stacks, trash the Bings get a set of "race" carbs. Mikunis or Delortos. There are complete drop in kits for that motor/bike. Kits can be optioned with velocity stacks with proper FOD screens that don't impede air flow like a piece of filter shoved down in the carb openings.
You are a awesome worker with incredible skills , fantasie for design, but everytime i see your working hands i know why i am wearing gloves whenever possible. i know that many worker say they need to feel more when the working and i thought in this way many years. but then i discovered the very new generations of gloves with perfect fit, no sweat and some with cutting protection for sharp edges. And the best: no cleaning hands 10 times a day! For you there are these black gloves for hairdressers when the dye perfekt. They fit like skin and no sweat and they are cheap. i use them all the time when i am painting or work with epoxy.
The fact that they are pointing backwards will actually cause a negative pressure area to be formed behind the stack, causing it to suck the air out of the carb, COMPLETELY negating any volumetric flow benefit of having a velocity stack design, and in fact impeding air flow performance into the motor
We seem to be missing the video on that bike wheel stand... would love to see it if you have it...it looks like a great idea...absolutely love this channel
great content, great editing, great making ! Could you quickly explain how you're engraving on metal with a laser ? It seems as if you've coated the polished piece with a compound before lasing, and then remove it. If so, what compound is that ? Can anyone enlighten me?
I paid over $1000.00 for a set of velocity stacks for my KZ1300/6. After I got the carbs adjusted for more "true air flow" you wouldn't believe the horsepower, lower E.T.'s, better over-all performance and the jump in gas mileage didn't hurt either.
Does anybody know if this bike's build has been chronicled anywhere? V-stacks aside, there are some other details I'd like more info on for a build I'm working on.
It might be easy for you but gorgeous machining like that takes years of practice to develop the required skills. However the stacks on the bike will not preform as well as the air box! A cone shaped air filter with accordion folds would help!
the one cylinder 4 stroke for each stack.. could get away with just a screen. Find some micron stainless mesh on the web. love that old bimmer flat two.. a legend
Not even counting the filters, that design of a velocity stack will actually drop airflow 1-5% over an open carb. A 7° angled stack with a 6mm radius 3/4 round on the end would give about a 5% increase in airflow.
Very nice. Are they the bits where the steam goes in or where it goes out? I do like a steamer. Also, how do you adjust the jets after you change the air delivery geometry or if it is injected how do you know how much or where or which parameters, or is it sea mail?

Great. A joy to watch a craftsman. Produce go fast shiny bits and then hear the bike lift up its head and roar down the road.

My kingdom for a mill/drill/lathe combo...
Beautiful work!
beautiful job.. but i bet it runs better with the long curving intake ducts from the air box. those curving ducts are also velocity stacks.
Yes, they are in a sense, but they're also very restrictive. A "straight-shot" of air travel is better for performance over a "plumbers-tuba" any day.

That´s what i thought also, too much air for the stock main jet, will hickup on throttle pull...

Agreed. These are show but no go parts.
Love how you turned these instead of using pipes and welding them, great work 👍
Absolutely gorgeous pieces.
Those look great but cutting the filter area down by 90% will create too much of a restriction at high rpms and the engine will run rich and lose power. You need to use a more porous filter to maintain the peak power of the engine but that will reduce the engine life.
And at full flow it might get sucked into the engine as there appears to be little support.
@@chrisstephens6673 In one of the shots it looked like he left a web to support the filter. I'm not 100% sure but I think I saw something there.
@@chrisstephens6673 sucked into carb first

love these little projects, keep em comming !
That polishing on the end after the laser work gave some scratches...

Nice little project - happy to see more of these in between the bigger ones. Looking forward to see what you have planned for 0100... 👍😊
Love that there's no backing track. I like hearing the shop sounds.
what kind of product do you use before laser engrave? awesome job!
Nicely done, but you absolutely do not understand how the carburetor works and that with such a filter the carburetor will not work well!
It just may need a rejet. Thats all
Serg in Seattle why wouldn't it work? The original air box is probably better but this bike is, most likely, mostly about looks.

That is fantastic. They look brilliant. But now the carbs are no longer attached to the air box, will they vibrate badly on the manifold rubbers?

Awesome workmanship, I hope you re jetted the carbs.
i dont understand why was this needed, or what does it improve?
Improves air flow, to make it work however you need to rejet it. After rejet, the power increases
engine wouldnt work long
Also forgot to mention, for the fuel injected ones. The ECU needs a remap if you put this stacks
