Introductions

"That's all the motorcycle is, a system of concepts worked out in steel. There's no part in it, no shape in it, that is not out of someone's mind." --Robert M. Pirsig

It moves when I use my feet.
So for Christmas I acquired a motorcycle... I am a computer nerd with a long love of sci-fy and a new found love of graphic novels. I am a game player who has been on one video game system or another since Pong was eating cathode ray tube TVs. I love to take things apart and try to put them back together, but I have never learned to turn a wrench on anything other than to adjust the brakes on my 10 speed Raleigh Technium 440 in high school.

When I moved from the city to the country in '99 I had never started a generator nor run a chain saw. My dad's lawn mower and weed whacker were the only small engines I had ever used and had no clue how to service them. I joined a fire department after 9/11/01—where we use a lot of motorized tools—and had to explain how I could be so experienced at cleaning up a hacked computer but didn't understand what a choke was. It's been a steep learning curve. And so in December 2015 I acquired a 1974 Honda CB360 (and a partner CB350 in parts, for parts) motorcycle that has been sitting in a garage for over a decade. God knows how long it has been since it actually ran. I'm told this is what people call a "project bike". This is our story...

It was born in the last quarter of the Internal Combustion Century...

"Each machine has its own, unique personality which probably could be defined as the intuitive sum total of everything you know and feel about it": We love to anthropomorphize our means of conveyance... give them names, attribute quirky characteristics to them, talk to them as if they can actually hear us... It's human to look for the humanness in other things around us, in the things we make sometimes in part of our own image. And it is in our mechanical machines that we invest so much of our efforts. It's hard not to be a little in awe of the simple complexities of our machines that were born of our cleverness and desire to create. Somewhere between the horse drawn cart and the self driving cars of today lies my 1974 Honda CB360. In my head it rolls, it conveys, it consumes, it breaths... It does have electronic components, but no circuit boards. It does have gears, and I have to shift them. It might move forward, but only if I roll the throttle and giggle a little at how cool that feels... All the "thinking" done in the engine is mechanical. It is just complex enough that I am overwhelmed by my 170 page shop manual and all the systems it describes, and just simple enough that wrenches, screwdrivers, pliers, and hammers will be most of the tools I need to make it run again...

No, my motorcycle doesn't have a name yet. I do not talk to it, nor does it have the ability to exhibit any personality traits as it sits dormant and noiseless. But I have found myself telling people that I wish to "breathe life" back into... (why do I keep thinking "her"?). The keychain that arrived with the bike was from the owner before the owner that I obtained the bike from. (Its history will be looked into if I can get it running.) That keychain from the 80s that accompanied the bike reads "Joe". Maybe my bike's name can be Joe. We'll have to wait and see...

"We’re in such a hurry most of the time we never get much chance to talk. The result is a kind of endless day-to-day shallowness, a monotony that leaves a person wondering years later where all the time went and sorry that it’s all gone": So I have a support team helping me, and videos on-line, and books on the shelf, and pages and pages and pages of shop manual... but at the center of this project is my friend Kevin. It's Kevin's garage, Kevin's tools, Kevin's patience, and Kevin's knowhow that is making my project feel possible... probable. I take direction from Kevin. I have relied on Kevin tremendously already. He clearly is the master-wrench in this relationship, and I his novice-apprentice. We get to talk while we turn our wrenches. We get to find the moment that lies between what happened and what might yet be. The moments just are, and for that I am grateful for them. For that I am grateful for Kevin. "Where do we start?" Answer: the engine. If we can't get the engine to run, there is no reason to invest in chains, pads, wiring, shocks, rubber, etc. Let's not worry about those things until we tackle the engine first. Start with the heart of the machine...

So I removed the seat (and made note that the lock needed to be fixed, and maybe a new cover for the cushion), removed the petcock (which had rock-hard cracked and brittle hosing and needed a serious cleaning), and pulled the gas tank (which smelled of shellac and was crazy-flakey with rust). I took off the air filters, loosened the battery cage, and removed the carburetors. All stripped of these parts, my motorcycle looks bare and kinda cool nonetheless. I was eager to play with replacing and repairing these parts, but we had to start with the engine...

"A motorcycle functions entirely in accordance with the laws of reason, and a study of the art of motorcycle maintenance is really a miniature study of the art of rationality itself": Kevin has the gauge one uses to check for the pressure created when the piston pushes up in the cylinder. If there is no compression, the seals (or worse) are broken and the engine would need to be opened and worked on. With a good compression test, we could bypass work on the engine and move on to other parts of the bike. The good news was that we got a 150 psi test in the right cylinder. The shop manual says a compression of 170 psi is perfect. 150 will do. The bad news was that we found that the left spark plug was the wrong size and the threads were stripped. No spark then no ignition. No ignition then no heartbeat. No heartbeat then no life... I felt a splash of anxiety rise and a little hope lost as I imagined my inexpensive project either spilling into costs I could not justify, or ending prematurely... Kevin quietly took over, patiently explained his processing, and for the next hour and some, carefully worked a properly sized plug in and out of the damaged threaded hole... successfully!

To have a combustive moment in the engine there needs to be a properly portioned mix of air (O2) and Fuel (C8H18) compressed and sparked. The fuel drops from the tank through the petcock (a valve and strainer) to the carburetors. Air is pulled in through the air filters to the carburetors, and the mix passes into the cylinder where the spark plug lights off the mix. The explosive force is captured by parts in the engine to drive the chain, which rotates the tires, and moves the man down the road with wind in his hair and a smile on his face...

So by the end of the first week or so we had the dirty petcock in the parts bath for cleaning, the tank filled with acidic vinegar to start removing rust and shellac, carburetor rebuild kits ordered and on their way, and new plugs in an engine that had whispered just a little at 150 psi...


Quotes from Robert M. Pirsig's Zen and the Art of Motorcycle Maintenance: An Inquiry Into Values

Getting Un-Stuck

Learning to let go should be learned before learning to get. Life should be touched, not strangled. You’ve got to relax, let it happen at times, and at others move forward with it.
― Ray Bradbury
Getting Stuck: So having gotten the CB360 running by summer was a priority for me. I was a year and a half from acquisition and was ready for the project to be over and the use to begin. I had expectations [warning]. I had attachments [Warning]. I had desire [WARNING!]. I wanted to feel the benefits of my efforts, and to feel free and unfettered. The 360 and me went out for a few unregistered spins around the neighborhood, but found the idle was off and the bike would die at strange speeds.

It was time to take stock of what was working and what was not:
  • The electric starter is dead (but the kick starter works)
  • Battery at least is powering the lights.
  • The gas is 93 octane with no ethanol and is getting to the carburetors.
  • Spark plugs must be working as I get a sputter and an occasional start.

What might not be working:
  • Points not adjusted properly after engine reassembly.
  • A problem with the valves?
  • The carburetor settings are all wrong?
  • Something else I was unaware of?!
Still Stuck: So I had come to a place where I was stuck. I wanted to repair my own bike (but I wanted to ride it even more than I wanted to continue to repair it), and was willing to have someone else deliver me to the finish line. I had relied so heavily on the aid of Kevin, and other Kevin, and Ross, that adding more consults and helpers hardly seemed like a real compromise to my education. My desire and attachment to riding had became more important than repair.

A plea: So I called my mechanic, Kevin, and asked for a referral. He directed me to Paul, a wise tinkerer who agreed to do a house call. What kindness from a near stranger! Spending almost two hours looking at the bike and teaching me more about its parts, he poked and tested and puzzled and smelled and finally offered his opinion:

Diagnosis: He suggested my spark was not a good color, and that I replace the ignition condenser, put on new points, and replace several fuses (they seems to be whole, but which were in fact, fried). It was a wonder anything was working. $45 later and a few weeks for shipping and I was ready to go:
Ignition Condenser
The ignition condenser is a standard "tune-up" part on any Honda CB350, CB360 & CB450 and is the most common failure part of the ignition system. Regardless of the condition of your Honda CB350, CB360 or CB450, condensers wear out. Yes they do not physically move, however as an electric component they are prone to decay. The condenser's job is to keep the ignition coil charged under high speed and to keep the points from wearing out prematurely. Signs of a bad condenser are burnt points that do not last very long (few hundred miles) before they need replacement. A failing condenser will also let the bike idle OK but tend to keep it from revving very high, AKA your engine seems to cut out at a random RPM and stay there. --http://www.common-motor.com/honda-ignition-condenser
Hope?: I was so excited. The bike basically needed its carburetors synched (which Paul agreed to help with), new rubber on the wheels, and I was ready to go. My impatience and lack of knowledge of rubber pushed me to contract with a local dealer to buy tires and have them put them on for me. It would be $450 and a blow to my "do-it-yourself" approach that was already a slippery slope, but I would be racing through the world soon enough to leave my pride behind. And that's good, right? Leaving one's pride behind?

Progress: And so I registered the bike, and bought insurance, and got my plates. I only needed to get inspected, and manage a  few other things, but I was Soooooo close to getting to ride...

...and the bike stalled out on the way to the dealership.

Betrayal: To make the story shorter, they had sold me the wrong sized battery back at the beginning of my repairs. The terminals were shorting out on the underside of the seat, causing all sorts of electrical problems. And so I got new rubber, drove home having bit the bullet for a new battery (and vowing not to return to said deanship for their lack of ownership for selling the wrong one in the first place), and stalled out one mile from my garage...

Expectations and disappointment: Electrical? Carbonation? Something else? I was losing my patience as I watched my reality and my expectations move further and further apart. And now I needed to get a 350+ pound bike back to my house up a steep hill before reassessing where to go next. Oh, and there was the new problem of the small amount of oil on the cylinder head with a broken bolt...

Impulsiveness: I tried a simple method of extraction. It seemed simple. I was so close and had this one little setback. With tunnel-vision for riding and full gallop toward my desired expectations I jumped in to do my own simple work for once... and made things much, much worse! I mangled the extraction, and damaged any easy removal by a more skilled mechanic. There is no way the bike was going to be ready before the cold weather of the Berkshires hit. I had lost my window...

...Perhaps it was time to throw in the towel on the whole—now expensive and time consuming—process. I was not finding my inner mechanic, nor any peace. I was not making my way to freedom or feeling unfettered. I was really stuck!

Taking a deep breath: I spent the next two weeks dealing with other life concerns, before deciding on what to do next on my bike. I spent some time online seeing what I might get as a sale price for "Joe," and what a newer cleaner bike might cost me. I felt like a failure and decided on inaction for the time being. And then I picked up Zen, and the Art of Motorcycle Maintenance again. I chip away at its pages slowly like a meditation. I hoped to pace my progress with the book along with the work on my bike. It's been a long read for sure. I was at the end of chapter 23 when I last put it down, and  so began reading again at the start of chapter 24. And this is what I came across:
Stuckness. That’s what I want to talk about today. (p. 270)
It was an uncanny topic for Pirsig to address. He goes on to illustrate stuckness with an example of a stripped screw on a side cover assembly. Amazing parallel!
Your mind was already thinking ahead to what you would do when the cover plate was off, and so it takes a little time to realize that this irritating minor annoyance of a torn screw slot isn’t just irritating and minor. You’re stuck. Stopped. Terminated. It’s absolutely stopped you from fixing the motorcycle. (p. 271)
This is the zero moment of consciousness. Stuck. No answer. Honked. Kaput. It’s a miserable experience emotionally. You’re losing time. You’re incompetent. You don’t know what you’re doing. You should be ashamed of yourself. You should take the machine to a real mechanic who knows how to figure these things out. (p. 271)
Let’s consider a reevaluation of the situation in which we assume that the stuckness now occurring, the zero of consciousness, isn’t the worst of all possible situations, but the best possible situation you could be in. After all, it's exactly this stuckness that Zen Buddhists go to so much trouble to introduce; through koans, deep breathing, sitting still and the like...

...If your mind is truly, profoundly stuck, then you may be much better off than when it was loaded with ideas...

...The solution to the problem often at first seems unimportant or undesirable, but the state of stuckness allows it, in time, to assume its true importance. It seemed small because your previous rigid evaluation which led to the stuckness made it small. (p. 277)
Normally screws are so cheap and small and simple you think of them as unimportant. But now, as your Quality awareness becomes stronger, you realize that this one, individual, particular screw is neither cheap nor small nor unimportant. Right now this screw is worth exactly the selling price of the whole motorcycle, because the motorcycle is actually valueless until you get the screw out. With this reevaluation of the screw comes a willingness to expand your knowledge of it. (p. 278)
And so I am learning to let go in order that I might at some point learn to get...
