Made a aluminum velocity stacks

[DING]

Bought a btmoto velocity stacks for 399bucks
And an idea came up to my mind. Why not make aluminum version of this thing? Coz the surface of the 6061 aluminum is surely smoother than glass fiber nylon which is btmoto's velocity stacks made off.
So yeah, here are some photos of aluminum version stacks

Friend's bike has BMC air fliter, yoshimura dual slipons + self made middle and front pipe. Bike is Tunned using woolich software from local tunner.
Red : stock stacks
Blue: aluminum version of btmoto stacks
Green: little adjust on the tunning part After installed the aluminum stacks.

Condition: 30 degrees celsius. Humidity: 78
Location: Philippine
97 gas (althought higher number, however, maybe same as 93 pump gas in US )

Maybe because the room temperature is way too high, that's why the numbers on the curve is not that ideal. In my city it is cold as fck.

And next time i will use my bike to run the dyno with both aluminum version and normal version of btmoto stacks. To make a comparison.

So the key to make ur busa faster
1. Lose weight
2. SF p185 air filter
3. Single Full exhaust system
4. A gen2 camshaft replacement
5. Lower ur bike
6. Mtc gen2 multistage clutch kit
7. Racing fuel
8. Aftermarket velocity stacks

Anything else?

Cool project, and an age old argument, which is best, a smooth or a rough intake surface?
Smooth for less turbulence, or rough for more turbulence, as to which is better.

A 520 chain conversion, aluminum rear sprocket, and aftermarket front steel sprocket will lose over 2 lbs of rotating mass.
Lighter rotors, lighter wheels, ceramic wheel bearings.

Does ceramic wheel bearing works that great? They are expensive

It's hard to say, but...
I put them in my friend's '18 Gsxr1k(which I store, work on, and ride)
I had put a couple hundred miles on the bike with the ceramic bearings.
I keep the bike on my Bursig stand, but also have been pushing it around for over 5 years now too, moving it here and there.
I was doing something else and needed to move the bike, I grabbed it by the bars and passenger seat strap as usual, and put the usual amount of effort in to push and pull it where it needed to go.
Immediately I noticed that this was much easier to do(I Always keep both tires 36psi cold too).
I rolled the bike back and forth several times, suprised that it was easier.
Then remembering that I had experienced this on another bike years ago.
The easiest way I can describe it is that if you have ever picked up what you thought was a near full gallon of milk, only to find out that it was almost empty, and your brain put forth the effort to lift the full jug, only to end up lifting it very quickly and easily before realizing it.
Are they worth it? It's still hard to say.
They are not really ceramic either, just a design and materials with supposedly less friction.
They are a Small part of 'every little bit counts'.
I also put ceramic transmission and output shaft bearings in that bike...which was probably good for .002 hp, lol

I see it works like a good or bad figet spinner. Good spinner stops like one minute and bad spinner stops like 30 seconds. Because one has better bearing with less friction

lol, that's a good way to put it.

Ceramic bearings and micro polishing are things that should be done if u have the time and money, bcuz if everything is done, it’s noticeable especially if being replaced by parts that were worn. The next motor I’m going to attempt to be patient and cryo, micro polish and use ceramic bearings all thru out.
