KDX Freebie Project

So not long ago I was lucky enough to find a motorcycle. For free. This, is it’s story.

The 1980 Kawasaki KDX. 175cc’s of vintage, 2-stroke thumping glory

I was helping my sister and brother in law move on the weekend of April 28th I believe. Afterwards, we decided to get some dinner. It was then that I saw it. Sitting by some mailboxes. I told my brother-in-law to pull over in case it was curbed…not having much faith that someone would just give that away.

We turned around and stopped. I asked a woman by her apartment if she new anything about it. She didn’t. I walked down a long driveway of apartments to see if I could find some clues. It was then that I saw a guy in his garage that was littered with motorcycles. I had a feeling I found the person I was looking for…

I talked to him for only about a minute. The conversation went a lot like:

Me: Are you giving this away?

His name was Brett.

Brett: Yeah, we have a lot of projects and I can’t get it into gear. If you put a vise-grip on the shift lever you should be able to drive it. The carburetor is in the box with it. The engine ran fine when I last drove it.

Me: So I can have it?

Brett: Yeah, I don’t want it. It’s yours.

So I took it! And there were a box of parts/components with it as well. I walked it back to my sister and brother-in-laws and then we got dinner.

Admittedly, I was like “4-year-old-with-face-covered-in-chocolate” excited about it. Ironically, when I was in high-school, I gave away a dirtbike for the exact same reason. It was stuck in gear and I didn’t want to take on the project. So in some cosmic sense, I feel like the universe gave me back my bike…and said…”fix this damn thing. It’s your destiny.”

So I decided I would. I pushed the thing back to my place. It was a nice three-mile haul. I parked it behind my apartment for a night so I could formulate my plan for it. However, I knew I had to come up with a better idea because it was not very secure in a parking lot.

It was then that I had the brilliant idea that I could just work on it in my apartment. It took a couple running starts but I got it up the steps. Not saying this to fan my pride…I live in a single bed apt. so there was no other place to work on it. As they say, out of necessity, comes pushing heavy objects up steps.

So I had it in my apartment for diagnostics. It did not even have the carburetor installed (the part that fuels the engine). It had compression though (good sign). It took me a couple days of internet research, looking at it, deciding what to do, before I could muster up the courage to start taking it apart. It was one of those moments where I knew that as soon as I started tearing it down, it may never get back together…

How to figure it out

Side note – You may be wondering, where do you even start on a project like this? I have never owned a motorcycle besides the high school one, and I never even touched that one. So how do you learn as you go? Well…I’m glad you asked.

Step 1. Buy a manual. I got a factory service manual on the electronic-bay for $8.

Step 2. Someone posted on Youtube exactly what you’re trying to do. I guarantee it.

Step 3. Find exploded diagrams online of the components you’re taking off/putting back together. There are diagrams for almost everything. If you look hard enough you should be able to find something. E.g. cmsnl.com sells parts for the bike, but I just used the site to see exploded views of the components. When you can see everything blown apart, it’s easier to see that motorcycles are really just glorified 3D puzzles that you can rip up the streets with after you’re done. See below.

Step 4. Have basic hand tools. I took the thing apart with basic hand tools that I already had. Try not to invest too heavily in new tools and only buy what you need.

Step 5. Find a forum. Trust me, someone out there WAY nerdier than you made a whole website dedicated to exactly what you are fixing. Connect with your people, and they will guide you. For this project, there is www.kdxrider.net. Whether you have a car, truck, computer, clogged ketchup bottle, anything, there’s a forum for it, trust me. A guy on a forum showed me a video he made so I knew what year it was.

Diagnostics and Teardown

At this point, I knew that the main issue with the bike was that the shifting shaft was broken, at least. I knew this because the shifting shaft splines were very mangled. That made it impossible to use the gear-shifter for it’s intended purpose.

Depending on how you look at it, this is either a simple fix or not a simple fix. For me it was relatively challenging. For a more seasoned bike mechanic this is probably one of the more simple jobs.

The first step was to get the engine off the bike. In retrospect this step probably wasn’t necessary, but it made it easier for me. Unfortunately I did not take that many pictures of that process. It was fairly straightforward though. If you scroll up and down really fast it can look like the engine just popped off.

Finding the offending component(s)

After the engine was out, I could take the crank-case cover and inspect to see if there was any other damage inside the transmission. First, I had to take the clutch off. That’s the big round thing in this picture.

Without clutch

As you can see, things look pretty shiny and not broken, which is a good sign. This picture already has the shift shaft taken out. The dead part is below.

I found the part # by using the parts diagram on cmsnl.com.

Funny thing about 1980 KDX 175 shift shafts…people really want top dollar for them on eBay…since it’s a pretty rare component, it cost about $100 after shipping to get a brand new OEM part. This is a NOS (new old stock) part.

After making the most reasonable offer I could on eBay, I settled for the price of $100.

Putting it All Back Together

So now that I got my new part, I installed it and could start re-assembling the bike.

Only one other unknown remained. I was nicht-so-sure about the carburetor. So I watched this YouTube where someone explained how carburetors work in a delightful Hindi accent. It is not about the specific bike I was working on, but the same basic principles apply. Gas goes into it, it mixes with air, becomes all atom-y, and then engine goes boom.

So I cleaned out the carburetor as best I could, and installed it on the bike. They tend to clog with old gasoline that turns to a gummy material.

This came with the bike.
You see that giant, gaping hole? That’s where the carb is supposed to go

I installed the carb and re-assembled the rest of the bike.

Fueling Up, and Using Some Old Indian Tricks

Since it’s a two-stroke, I got some 2-stroke oil to put in the gasoline. After spilling a lot of fuel out of the no-spill container, I was ready for the moment of truth.

Will it run!?

Oh hell yes it will. I sprayed some starter fluid (the trick) in the air intake and it fired right up!

Smoke means it works. Frankenstein lives.

Additionally, the shift shaft was the only issue with the gear shifting, so I took it for a spin. It shifted through all the gears just fine.

Sew much fun

Part of the joy of something like this is the risk of becoming road kill. In the middle ages, brick-layers had to stand under the bridges they build as the key stone was put in place. If there work was crap, they would just let the bridge fall on them and crush them. I think that’s a good way to live life. If you don’t trust your own work, who’s can you?!

Is it worth it?

Some hobbies cost money. If you play things right, you can get your hobbies to pay you. I kept tabs on the amount of $$ I spent on the bike, as well as rough guesses on the time I spent.

Overall I spent $260 on a free bike in parts, gaskets, oils, and tools I needed. I ended up selling it soon after for several reasons. Kind’ve wish I would’ve kept it, but you can’t turn back time…I sold it for $423. Which doesn’t seem like much, but hey craigslisters weren’t biting at the $600-800 range. In perfect shape I’d say this bike is worth $1300 so just use that for perspective.

However, I did A: make money B: learn a lot C: feel more prepared to own another motorcycle.

It wasn’t really all about turning a profit, but I don’t want to make money pits for myself either. There are a lot of people who will just sink cash into projects like this and it’s not worth it I’d say.


I hope you enjoyed reading about his build/repair as much as I liked doing it. If you ever get a chance to get an enduro…I highly recommend it. They are good fun. And remember, don’t be safe!

Here’s a thump video:

Side notes/Resources:

This guy was a big inspiration for me. Down-to-earth guy and his wife make trashed bikes work…he has a big following. He did a similar project on an old Kawasaki.

Jennie’s Garage

I also drew some inspiration from this book:

Full Open Source Motorcycle:

Someone developed a motorcycle that can be sourced completely by local machine shops. It can be made fully street legal. I found this project before I found the bike. It is entirely different, but is still a really cool idea.


How Wabi and Imperfection Gave Me Peace of Mind

As I look around at the general shortcomings of not only this blog, but my life in general, I had to take some time to reflect on where I was. Like many other times in life, I got an answer from one of my favorite books of all time.

人和書 ( Men and Books) : Zen and Japanese Culture: 禪與日本文化

On page 284 the page reads:

[speaking of wabi] And wabi is not merely a psychological reaction to a certain pattern of environment. There is an active principle of aestheticism in it; when this is lacking poverty becomes indigence, aloneness becomes ostracism or misanthropy or inhuman unsociability. Wabi or sabi, therefore may be defined as an active aesthetical appreciation of poverty;

To put this another way, wabi is the appreciation of the beauty that is the result of imperfection.

If an object has wabi, it can be thought of as having “character.”

I think that the meaning behind this is that there can be hidden treasures lying underneath troubled circumstances. The person who understands wabi realizes his trouble: his lack, his want, his failure. But despite the knowledge of this, the person decides to reshape his impoverished environment.  Doing the absolute best they can, and with a genuine heart.

And with the study of wabi, the genuine heart is the gold that emerges from underneath the trouble. The other benefit is the authenticity that comes with overcoming a problem while living within your means.

House Hunting

Now that I am nearly finished with a car build that I have been working on for a few years, I am focusing more attention on purchasing a house or condo.

There are a few reasons that I would like to buy a house this year.

The first reason is that it will save money long-term in comparison to renting. I have heard counter-arguments to this, and the woes of homeownership costing huge amounts of money: roof leaks, plumbing repairs, etc. However, it is hard to quantify the cost of home repairs a place would need before purchasing.

However, let’s take a look at potential costs of home ownership versus renting. Say you pay $600 a month in rent. That’s $5000 a year. That is relatively flat, with no home repairs needed.

Okay, let’s compare this to home ownership. Your mortage is $600 a month. You have to pay a plumber $700 once, and you pay additional taxes.

Maybe your grand total is $7,000 a year, and you have to pay an additional $2,500 in property taxes.

So that’s $9,500 vs. $5000 if the math is right. Ok, so it looks like renting is winning. But let’s consider the fact that your $5000 goes to the landlord and is not invested in any way. It basically just goes out the window.

The house on the other hand, you get to recoup some of the money spent.

I ran a projection for a 15 year loan on a house.

Frankly it doesn’t seem worth it unless a very substantial down payment is made. Over 15 years with a ~5% interest rate, you could be paying almost double what the house is worth.

Western Tradition, Symbolism

It’s been a while since I’ve written a long-form post. In fact, lately, it’s been more of “haven’t posted in a while, so here’s something quick!” So I’d like to just put to paper a lot of ideas I’ve had lately. These are things that I’ve observed and I think the reader should see a connection as well.

I’ve noticed that a lot of people in the USA are very opposed to Western mysticism in a variety of ways/forms. I’ve also noticed that many people are really receptive to Eastern mysticism—particularly yoga or eastern forms of meditation.

I guess what I don’t understand is why people are closed off to the Western mystical traditions in favor of the East. I think there are a variety of reasons. First and foremost, I think Western mystical traditions are a repressed aspect of our culture. This is in spite of the fact that many major Western scientists, mathematicians, and revolutionary thinkers dabbled in Western mysticism. I also think that the West is not developed enough to understand ideas that go beyond logic, although there were/are many Western scientists that are pushing for greater understanding of irrational ideas and paradoxes.

For example, Isaac Newton had multiple manuscripts about the philosopher’s stone. Leibniz was influenced by the I Ching.

I suppose another reason that the West is largely closed off to it’s own traditions of mysticism is because they do not even know they exist. We are usually told that Christianity is the basis of Western culture, which is only partially true. Christianity has greatly influenced Western civilization, but there are other “root” structures that affect our way of thinking that run so deep they can’t be ignored.

Symbolism Cropping Up

Another thing I want to point out is how repressed mystical thought ends up cropping up in our culture in really unexpected ways. The main way that repressed mystical thought pops up is with societal obsession with fantasy movies, superheroes, and things like that. Take Harry Potter for example. The same people who insist on their rationality have no problem spending $15 to see a wizard child fly around, buy books, and even dress like him. All while insisting it’s just make believe. What they usually don’t know is that JK Rowling borrowed a lot of ideas from Roman/Greek thought, pagan/norse influence, and alchemical thought. Take a look at the images below. What do you see?

The Harry Potter snitch

The winged sun, from the Rosary of the Philosophers

Does this look familiar? Looks a lot like the snitch, doesn’t it? This idea was borrowed, or maybe stolen, from the Rosary of the Philosophers (1550). It runs even deeper than that though. Check out this other image below.

The caduceus or the staff of Hermes. It is now used to represent the medical profession (sometimes)

Hermes with Caduceus

In the caduceus you see again the idea of a golden ball with two wings. This time it is on a staff with two serpents wrapped around it. I’m going to go out on a limb here and say that this is another “enlightenment” symbol just like the winged sun and the snitch. In the “snitch” case, if you retrieve it, you win the game of Quidditch. This is a metaphor for the other symbols. Capture the mercurial sun, or the staff of Hermes, and you “win” a game in life so to speak. They are all mythological ideas that correspond to life experience as a human.

The staff’s serpents represent the Western form of the idea of “kundalini” as it’s called in the east/yoga traditions. This is the idea that human life force resides in the base of the spine and rises up the spinal column to the brain where it can be transformed or causes a change in the human brain. Hence the two serpents coiled around the staff (the spine) rising up to the golden winged ball (human head).

What’s the Point?

I guess at the end of the day the point is that these ideas are repressed but still a part of our collective Western psyche. Enough so that they still awaken fascination in people when they are seen, despite the historical background not really being obvious. They make such a deep impression that people “get” the idea unconsciously.

The other point is that the West has it’s own traditions of higher human understanding just like the East does with Yoga, Zen, Buddhism, and so on. It is just that many of these ideas were repressed for centuries and even up until modern times. And even better, the ideas tend to run in parallel with eastern though (the kundalini idea as mentioned earlier).

The other point is that it could be easier for Western people to understand their own culture than to try to understand and adopt another culture’s religious and mystical traditions. Since english is partially based on Greek, Roman, and Latin, the words are easier to understand and relate to. And since our psyche’s foundation rests on Greco-Roman-Egyptian traditions, the ideas are usually easier to digest than those from China/India/Japan and so on.

Website for SMART-Treat™ MBBR

Check out the new website for SMART-Treat™ MBBR here. This was a simple WordPress build. It’s hosted on a Digital Ocean droplet. Encrypted with free Let’s Encrypt cert. Cost’s only ~$6/mo to maintain.

This was a “one-man-band” type build. I did everything.

I like working on these projects because it gives me freedom to make design decisions, work in the server’s back-end, and work with command-line interface.

Also, I like the product. It’s an innovative approach to cleaning water at a small scale.

Pilot Wave Theory: An Alternative Explanation to the Double-Slit Experiment

bouncing silicon droplets
An image of silicon droplets bouncing on oil, imitating the behavior of light particles according to Pilot Wave Theory

“Instead of non-real waves and real particles, why not just have real waves that push around real particles?” – Matthew O’Dowd, faculty at CUNY

There are a lot of weirdness in the quantum physics world. So much weirdness that quantum physics actually refers to some phenomena as quantum weirdness. And believe me, it lives up to it’s name. One example of very weird behavior is the wave-particle duality of light. The wave-particle duality is an explanation for how light behaves. Basically, it says that under certain circumstances, light is a particle. Under other circumstances, it behaves like a wave. Specifically, there is one experiment that is the “classic” case of demonstrating the apparent shift back and forth between the states called the double-slit experiment. The reason this topic gets attention is because of the outcome. Scientists expect electrons being shot through a double slit to behave like a particle — producing only two lines on a screen, but it behaves as a wave, producing a pattern of lines.

The current consensus explanation is that light can shift between particles and waves depending on the scenario. However, there is an alternative! The Pilot Wave Theory of light provides an excellent explanation for this experiment. It is also highly intuitive. Basically, it states that light does not shift between particle and wave, it is both at the same time. It is basically light particles riding on light waves, like surfers riding on ocean waves. This theory has a lot of traction in physics circles, but tragically is not accepted by mainstream science. This theory accurately explains the outcome of the double-slit experiment and challenges firmly held beliefs about the nature of light.

The double slit experiment shows how light behaves

Let’s zoom out here, and see exactly what the double-slit experiment is. The double slit experiment starts with the single-slit experiment. The single-slit experiment is basically setting up a particle beam that shoots either photons (small particles of light) or electrons through a slit in some kind of shield. The media shot through this is then observed on the other side.

1 Double slit Exp Single slit results | From the mid 1600 ...
The single-slit experiment produces results that we expect. A beam of light goes through a slit and produces a single strip of light on the other side.

Like the illustration shows, the single-slit experiment produces the expected result. This is how light acts as a particle. It travels straight through and produces a strip of light on the screen. Nothing really strange here at all, eh? But things get strange when another slit is added to the slit partition.

Superposition, Interference and Decoherence - Quantum ...
The double-slit experiment produces an interference pattern of light, similar to how a wave would behave.

Didn’t see that one coming, did ya? Well neither did a lot of scientists. However, when we now view light as a wave, the reason this happens is pretty clear. The waves are stacking on one another and producing an interference pattern on the screen. Essentially, waves of light are constructively and destructively interfering as they travel towards the screen, and producing the pattern of light and dark fringes. View the illustration below to see a visual of this.

As a wave goes through the two slits, it produces two waves that interfere with one another, producing an interference pattern and the resulting strips of light particles on the back screen

So what is the confusion exactly? Well, the confusion lies in the fact that the particles being collected on the back screen are behaving like waves. Remember in the beginning of the article when I talked about how the particles are collected on the back screen? Take a look at what they look like.

Strange! So it appears as though the light/electrons do in fact behave like both particles and waves. The particles are going through the slits, but they are distributed exactly like waves would be. But the current explanation is…they change between the two?

Enter Pilot Wave Theory

The alternative explanation to the wave-particle duality is to model the light particles as moving on waves. This is referred to as Pilot Wave Theory. This way, we don’t have to believe that light somehow flips between one state and another in a logic-defying way. Take a look at the animation below of the double-slit experiment. It accurately depicts a discrete light particle riding a light wave to it’s destination: one of the interference patterns bars on the back collection screen.

Pilot Wave Theory and Quantum Realism | Space Time | PBS Digital Studios
This animation from PBS Digital Studios provides a visual of the Pilot Wave theory. Light particles “ride” the waves of light, instead of transforming into them. The particle takes a specific trajectory (based on classical wave mechanics) and hits the screen as expected.

Where is this theory from? A man name Louis de Broglie formulated this theory in the early 20th century. He modeled the light waves using the Schrödinger equation. [For information regarding the origin of the Schrödinger equation, please read this article]. However, his idea was ultimately rejected at the Solvay Conference. Mainstream academia’s strict adherence to Einstein’s general relativity and special relativity do not allow for light particles to travel on “guiding waves” as de Broglie describes. However, the elegance and brilliance of pilot wave theory has maintained many followers since it’s inception, and has lead many to abandon Einstein’s theories altogether in favor of de Broglie’s.

Einstein’s (fifth from right, bottom row) relativity theory overcast de Broglie’s pilot wave theory (third from right, middle row) at the 1927 Solvay Conference in Copenhagen, Denmark.

One person who pushed Pilot Wave Theory to a new height was David Bohm. David Bohm completed the Pilot Wave Theory. In fact, it was even renamed after his work in the 1950s, giving it it’s current name: de Broglie-Bohm Pilot Wave Theory.

David Bohm.jpg

There is a PBS Space Time publication that does an excellent job explaining the history of Pilot Wave Theory, and provides the back story of it’s formulation. In a nutshell, a scientist name Louis de Broglie came up with the theory in the early 20th century. His idea was rejected in Copenhagen quantum meetings, however. Other contemporary quantum leaders such as Neils Bohr and Werner Heisenberg were adamant about rejecting “classical” physics in their interpretation of quantum phenomena. Maybe they threw out the baby with the bathwater, though. but was revived by David Bohm in the 1950s.

The “life-sized” counterparts to pilot-wave theory

Analogous experiments that show Pilot Wave behavior can be reproduced at a human scale. Physicists like Yves Couder use silicon droplets bouncing on oil to demonstrate the particle-wave interaction. The particle bounces up and down, and generates a wave that pushes it. Below is a real example of silicon droplets in a double-slit experiment.

Yves Couder . Explains Wave/Particle Duality via Silicon Droplets [Through the Wormhole]
The appeal of Pilot Wave Theory is that it does not stray far away from classical physics—let alone throw it away like Einstein’s quantum theory. Scientists such as Yves Couder demonstrate the same double slit behavior with silicon particles visible to the naked eye.
As you can see in the footage (not an animation!), the bouncing silicon droplet picks a discrete trajectory. Staunch physicists may say “the quantum world does not behave like the human scale world.” But this kind of thinking is a hindrance to progress. After all, why shouldn’t it? Why do we need to weave stories about light particles transforming into waves when more intuitive  (or perhaps even obvious) explanations exist? I will leave that up to the reader to decide.

“In physics experiments, you only see what you are prepared to see.” – Researcher Yves Couder, University of Paris-Diderot, (producer of human-scale silicon droplet double-slit experiment)

Summary and looking deeper

Pilot Wave Theory is an elegant solution to the wave-particle duality problem. Instead of making mystical demands of scientists, and making ridiculous claims about wave particle transmutations, it gives an intuitive explanation for the double-slit experiment. The main reason it is rejected is due to political ignorance and orthodoxy surrounding Einstein’s flawed general relativity and special relativity doctrines. However, the theory has gained traction in circles mainly outside academia ever since it’s inception. Please investigate the theory for yourself and leave a comment with any errors or suggestions.

In a nutshell, Pilot Wave Theory suggests that light particles travel in discrete paths as particles, guided by waves.

Pomodoro Timer

Well golly-gee! Thanks for taking the time to take a peek at this!

I am posting a link here to a project I wrote on CodePen.io. It’s a pomodoro timer. For those who aren’t familiar, the pomodoro technique is a method that helps people fight procrastination and the fear of starting a project. It does this by challenging someone to only spend 25 minutes on a task, rather than hours. This helps break the “fear barrier” of starting a project (the “aw shit I gotta spend all day on this” mentality). In addition, it helps with focus because the other rule to using a pomodoro timer is that you work distraction-free for 25 minutes. No cell phones, no talking to other people, just 25 minutes of solid effort toward a specific goal. It has worked wonders for me and many other people. Please check out, and use the pomodoro timer I created!


  1. Decide on the task to be done.
  2. Set the pomodoro timer (traditionally to 25 minutes).[1]
  3. Work on the task disctraction free, no cell phones, notifications, pointless email checking, Facebook, etc.
  4. End work when the timer rings and put a checkmark on a piece of paper.[5]
  5. If you have fewer than four checkmarks, take a break (5 minutes), then go to step 2.
  6. Do as many pomodoros as is comfortable, usually 1-4. If exceeding 4, take a long break after 4th (usually 15 mins).
