Pulling the Carbs

The Concours’ carburetor has become cursed by demons.  These carbs tend to not come back from sitting very well, though last year they didn’t have this problem.  When I put them away they were running well, but no longer.

Yesterday I pulled the tank again and went over the vacuum tubes in detail – no breaks, no problems.  After putting it all back together again I took it out and had the same hesitation on throttle and back firing.  The bike feels seriously down on power too.


I was hoping to send the carbs down to Shoodaben Engineering in Florida for a spa session with Steve.  His prices are more than fair, but after having an economist (whatever the hell that is) as a Prime Minister for eight years, Canada’s dollar is in the toilet and my $500US carb repair would cost north of $800 with shipping, customs and the exchange rate.  I paid $800Cdn for the bike in the first place.

So I’m rebuilding carbs!

In spite the many terrifying stories of carb removal on a Concours, I found the process pretty straight forward (thanks to Steve’s video).  Warm up the rubber on the airbox to carb, they get nice and soft, and you wiggle the whole thing free.  With the carb on the bench, parts are ordered ($200Cdn for 4 kits – 1 for each carb) and I’m beginning to break it down to rebuild each.







There is always one more thing…

The open road awaits, and it’s still waiting…

Recent frustrations with the twenty two year old Concours had me saying yesterday, “I like doing mechanical work, but sometimes I just want to go ride a fucking motorcycle.”  It was a day in the mid teens Celsius (almost 60 Fahrenheit), and the sound of motorcycle engines could be heard on distant roads.  After spending the winter redoing the brakes, wheels and bearings, I got the Concours back on its feet only to find the carburetor has gone off.  The bike is running lean, not fueling nicely and back-fires when coming off throttle.  Instead of going out for a ride on one of the first nice days of the year, I was popping and swearing my way up and down the road by my house trying to get the carb to play nice.

Some vacuum diagrams on there, but not where they go.  Another
suggestion for lean burning/back firing conditions (which I have) are
the air cut valve (highlighted).

Some research into Concours carbs produced a baffling array of opinion and vitriol.  It appears that no one who works at a dealership has the experience or time to do carbs properly any more, and the carbs on the Concours are fantastically complicated.

I’ve done carbs before on cars, and labyrinthine vacuum tubes aren’t a problem when you have a diagram to follow, but Clymers doesn’t include one in their manual (unless it’s for California bikes), and the Kawasaki diagrams show bits of vacuum diagram spread across the valve head blowup, the carb blow up, the fuel tank blowup, air box blow up and others.  Needless to say, trying to chase vacuum connections across half a dozen diagrams isn’t easy.

Today I’m taking the fairing I just put on back off, removing the gas tank (again) and trying to make sense of the vacuum tubes.  If nothing obvious presents itself it’ll be time to remove the carbs and go deeper.  I just did something similar on the XS1100 in the fall.  I haven’t had time to work on it since because I’m spending all my garage time on the Concours.

I’m starting to think one project bike is enough.  The other one needs to be modern, dependable and there when I need it so I can, sometimes, you know, just go ride a damned bike.

CoG wisdom on Concours carbs:
Normally it is caused by dirty carbs and and not being sync’d properly. The dirty part can be from just a few days of sitting due to the ethanol evaporating….


it’s very likely during the “cleaning” they did not dissassemble the air-cut valves from the 2 carb bodies prior to spraying with volatile carb cleaner. internal to each of those housings is a very delicate diphragm, not unlike the ones that lift the slides….during this process they damaged them, and at the least, never cleaned the rod attached to those diphragms that during decell, when the diphragm moves, opens a port to add fuel to the intake tract to preclude/prevent a “lean burn popping” upon decell. That is the sole purpose of those 2 valves, when they don’t function, you get this result.

Check the vacumn stuff like you already mentioned. I had a back fire for a while, peeked under the tank, found the rubber cap on the #3 carb was split. Just for the fun of it, replaced all the hoses while there, good to go now.

You Cannot do away with the reed valves entirely unless you tap the ports in the actual valve cover and thread in some set screws. The easier way here is to leave the reed valves and metal covers on the valve cover, and remove all the vacuum hosing associated with the pair valve. Go to your local auto parts store, and pick up three 5/8″ “heater core block off caps”. They look like big vacuum caps, and also some 3/16″ regular vacuum caps. Using the 5/8″ Cap off the 2 ports left on the valve cover, and insert one backwards into the airbox hole. Use the 3/16″ to block the intake ports.

Carbon KLX

Never a fan of the sticker covered MX look, I don’t care for
big, white, fridge-like panels designed to take numbers.

I can’t seem to own a bike without re-imagining it.  The Ninja went from flat black to blue and orange.  The Concours is continuing a transformation into gold and crimson.  Now it’s the KLX’s turn.

The white plastics on the KLX look cheap, appliance-like and nasty.  To rectify that I started looking for carbon pieces but they tend to be focused on sports bikes and I couldn’t find any KLX sets.  

I then looked for replacement plastics I could experiment with, but they aren’t cheap.  My next stop was sticker sets, which tend to be even more juvenile than the original graphics set-up (though the black metal one looked alright).  Why is everyone fixated on death imagery (skulls, bones, flaming effigies, etc.) on motorcycles?

A short term fix is to just focus on the offending pieces
(the headlight surround, fork protectors and rear side panels).

Amazing how five panels makes the bike look so different.

Longer term I’d like to learn how to form carbon fibre panels, but short term I’ve found a number of cheaper fixes to my aesthetics problem.

Canadian Tire sells the Dupli-Colour carbon fibre kit for about forty bucks.  It comes with two colours and a patterning cloth.  I should be able to sort out the natty white panels (two front fork guards, the headlight surround and the rear side panels) with that kit.  It’s a cheap, short term fix.

I was reading about a vinyl wrap project Performance Bike UK was doing last night.  They did the whole bike in vinyl, but you can pick up carbon fibre look vinyl for next to nothing.  Maybe I should try that instead of the paint.  After some looking up on Amazon.ca I found some carbon fiber look vinyl wrap that will let me try out what PB did with their Suzuki on a smaller scale.  I also found some mirrors on hand that are much less derpy than the stock KLX mirror, and the

$45 for shipping on a $27 part?  Really Amazon?

price seemed reasonable until I got to checkout – this Amazon ‘retailer’ is charging $45 in shipping for a $27 part.  They can’t be selling too many of those.  Fortunately I found a similar mirror with reasonable shipping costs and ended up getting a body colour mirror, 4 rolls of carbon look vinyl and a vinyl applicator for the same price as that over inflated shipping price, taxes and delivery included.  Amazon is no longer Amazon, it’s a whole bunch of sometimes shady online sellers.  It’s more like ebay than Amazon of old.

With more cash on hand I’d like to swap out knobblies for something more road focused and dualsport/scramblery.  Having the knobblies around for intentionally deep off-roading will be good, but I think I’d use the bike a lot more if I could get places without the tires slapping the pavement like wet squid suckers.

Canada’s Motorcycle has Shinko 705s in the right sizes for under one hundred bucks each.  Two hundred and fifty bucks in and my carbon fibre KLX will be a step closer to the more road friendly scrambler I’ve been dreaming of.







Further research unearthed some pretty cool options.  This twin light headlamp seems pretty Airwolf cool.

















Acerbis does a variety of front ends for enduro/dual sport bikes, like this Cyclops one.  

Nano-Tires

I installed Counteract balancing beads on the slowly-being-rebuilt Concours today.  If you’re impatient you’ll find the installation process a bit tedious, but the technology sure is cool.

Some have complained of liquid based self-balancing processes damage the tire, but the Counteract beads are micro-sized, synthetic beads that migrate to the out of balance side of the tire through static and centrifugal force.  Since they’re internal it means there are no unsightly weights stuck to my lovely new tires.  The claim is that these beads work better than weights as they adapt to the changing conditions throughout the life of the tire.  I’m hoping that they work as well as advertised.

On a cold, windy Saturday in February, I put the beads in through the valve stem using the provided small, plastic bottle, you keep gently squeezing air into the tube which pushes the beads into the tire…


The kit comes with valve stems and fancy caps as well.  Once I’ve had the new tires out on the road I’ll update this with an assessment of how well they work.

Update:  it’s late March and I’ve had a couple of chances to take the bike out.  I’m surprised at how well the beads work.  The wheels start off smooth and only seem to get smoother the faster you go.  Once I’ve gotten the carbs sorted I’ll be able to give a more accurate description, but early indicators are good.

Cabin Fever

I might be getting a bit jumpy waiting for spring…

I tried starting up the KLX on Wednesday when it was 15°C.  I thought I might ride across town to pick up my son from daycare, but I couldn’t get it going.

Today I got it going by giving it a blast of quick start with the air cleaner box open.


Consumerist Learning

I tried carrots, sticks and begging. I offered repeated hands-on opportunities with thousands of dollars of equipment (that I maintain just for their use), access to the latest industry standard training methods and information, flexible deadlines, and just about everything else imaginable. We’re at semester’s end and I’m exhausted trying to get students to take an active role in their learning.

As consumerist thinking gets more deeply embedded in our culture more and more students think I’m some kind of educational store clerk who isn’t doing a good job of serving them. The only relationship they can understand me having with them in the classroom is that of an employee. This isn’t only a student perception. Many of the powers that be would love to see a de-professionalization of the teaching profession (it’s cheaper!). This is a current social trend.


Disaffected students looking to control how I assess them fall into two camps: the risk averse academic and an exciting new kind of student: the five-oh (a term coined by seniors at my school for a student who is aiming for a grade in the forties because they know it’ll be rounded up to a pass). You don’t have to do an awful lot to get a mark in the forties. You can miss weeks of class, not hand in major assignments and fail tests but still pull off a forty. You also tend to do a wonderful job of poisoning a classroom when this is your approach.


What drove me around the bend this week was several of these poisonous five-oh’s approaching me to complain about their term grade. One seventeen year old who had missed three weeks of class and failed to hand in multiple unit summatives, all while playing games on the class PC and ignoring instruction even when he was there, approached me to demand an explanation for his terrible grade. It was somehow my fault that he categorically refused to do anything useful. I suggested we look at his participation in the current group-study project for the final exam. He hadn’t even signed up for it – he is nothing if not consistent. I told him something that’s as much a survival mechanism for me as it should be a consolation for him:

“look, you don’t care. You seem to be OK with that, and I can live with it too, but not if you’re going to come up here whining about grades you haven’t earned. The grade you have is charity, but you come up here demanding more. If you’d have put in any kind of effort at all I’d be doing back-flips trying to help you, but you didn’t, and you still aren’t. Your grade is reflection of your terrible work ethic. I don’t know what you know, but what I’ve seen suggests it isn’t much. That’s also a result of your work ethic. Are we done here?”

It turns out we were done there.


Less bothersome because they don’t actively work to dismantle the entire learning apparatus of education is the risk-averse academic. I’ve run into ‘you don’t teach properly‘ frustrated student thinking before. This is inevitably spouted by a relatively successful student who has been taught to be a passive consumer of learning in an overly structured and systemic classroom. These students tend to be academic kids who have figured out the game, and like the five-oh, they are looking to exploit it while doing as little as possible themselves. You give me pointless, linear, obvious information, I consume it then regurgitate it for you. You think I’m very smart and give me an ‘A’.


Marking exams the other day I came across just such a ‘you didn’t teach us anything’, they got this in the response section:
“I didn’t really teach you?  I have provided you with gigs and gigs of material and thousands of dollars of hands on equipment in an environment designed to support everyone from experienced to brand new learners. If you think learning is someone putting ideas in your head you’ve misunderstood learning (telling people what to think is indoctrination). You learn when you internalize information, and that happens best when you are the one discovering it.  You can’t own knowledge you haven’t earned.  Learning isn’t a handout, you’re not a passive consumer of learning, it’s an active endeavour on the part of the student.  If you’re waiting for someone else to tell you what to think, you aren’t learning anything at all.”
 .
This is a relatively successful student who refused to make mistakes and sat there passively, waiting for clarity. Clarity means getting concise, linear directions that make clear a pointless exercise (so you can follow the pattern and get an ‘A’). Guess what his parents do for a living? Yep, they’re teachers. Fortunately for him (if not for learning itself), he’ll find many teachers more than happy to play the game with him. I encourage and reward failure and admire brave attempts at understanding stochastic processes that defy easy description. I guess I’m a nightmare of a teacher.
.
Between the insidious five-ohs and the ever-so-smart risk-aversers, I’m exhausted.  I’d day dream (as other high school teachers do) about teaching in post secondary, but this consumerist thinking has infected it too, with helicopter parents demanding to know what they’re paying for when their university child (in their twenties) gets a low grade.  I’d prefer to teach high school anyway, you get to help a student find their way from the ground up.  When it works it’s very rewarding.
.
Thank goodness ‘tech millionaires’ (the same people who have monetized your attention) have a solution to one of the last non-economic human relationships left in Western culture (I bet it involves monetizing the teacher-student relationship somehow!)

You’d think that teaching an optional subject like computer technology would get you out of the five-oh infection, but thanks to guidance dropping kids into a class they have no background in just to fill up their time tables, and the five-ohs themselves seeking out courses that they think will be easy (computer engineering?  that’s video games, right?), I’ve had a rough semester.  The next one doesn’t  look much better since I’ve already found half a dozen students parachuted into senior computer engineering classes without the required requisite (computer engineering?  that’s playing video games, right?).

.

I’ve spent thousands of dollars and hundreds of hours of my own time getting comp-tech certified as a teacher and building a department up. This year is the first time I’m teaching a full schedule of computer-technology courses, but half way through it I find myself wishing I’d never left teaching English. I thought that teaching computer technology (a passion I’ve had since I was a child) would be thrilling, a chance to help other kids like I was develop into capable engineers and technicians, but between risk averse passivity and the rising tide of learning poisonous five-ohs, I’m left gasping for air.

Motorcycle 3d Modelling

I’m teaching a class on 3d modelling in Blender next semester, so what better way to practice than on my partially taken apart for maintenance ZG1000?

The model was made with the Occipital Structure Sensor 3d Scanner.  I’m trying different editing programs.  I used the 3d Builder integrated into Windows 10 to edit out the extra bits captured by the scanner.  It’s quite easy to use and has some pretty good editing tools.  If you’re trying 3d modelling for the first time it’s not a bad place to start (and it’s included in Windows 10!).


The file is shared on Sketchfab, which I find to be an easy way to do presentation editing and sharing of a 3d model.  We’re using Blender in class, so I’ll be cranking out some Blender motorcycle models in the next couple of weeks.  The trick is going to be to get them looking life like rather than digitally modelled.  I wonder how you model patina…





Difficult Metrics: The end of Creativity & Play in Learning

CBC’s Spark had an interview with Scott Barry Kaufman this week about his theories on creativity.  His identifiers for creativity include solitude, introspection, daydreaming and having new and varied experiences.  This reads like a laundry list of things education does poorly, or not at all.

The linear and systemic nature of learning in the education system is always on my mind as summatives happen and semesters end.  As I watch the system trundle towards final assessment (which means a lot of number generation), I’m always left wondering where the learning went.


Sometimes the internet feels like a meme confluence.  In this case related ideas of creativity and play mix together, making me question education’s intent in designing learning environments that stifle both things.  From the education system’s perspective, play is what you do when you’re not learning, that’s why they call it recess, yet Kaufman and a number of other thinkers believe that play is an incredibly rich learning opportunity.


A tweet by Mathias Poulsen on the marginalization of play in society got me thinking about the role of play in learning.  Play and creativity are inexorably linked in my mind.  When I play I create.  When I create, I’m playing.  I usually learn an awful lot in such a rich environment as well.

There are two aspects of modern society that drive the control paradigm Mathias refers to in his tweet.  Both flourish under the watchful eye of neo-liberal value theory.  Data collection is one aspect of this economic/social model and it’s happily provided by digital technology which seems designed to produce this sort of data.  With everything itemized the next step is to monetize it.  With absolute oversight better profits are ensured, but only for the people who can afford the absolute oversight.

Modern economic theory touts data driven metrics as the way toward a more perfect efficiency, and education has been eager to leap on board this very rational (at least that’s how it’s marketed) approach.  By quantifying everything we’re able to better manage people and property, not that there is a distinction.  The people who manage us are obviously big fans of this data driven approach.  It lends the air of mathematical credibility while also offering an automated ease of use.  No more worrying about people as people when you’re managing them from data.

toy_story_man_connect_dots
Data increasingly connects the dots and defines who you are. It used to be a more organic process but now it’s done by machine.

It seems like an air-tight trap.  You are what you do and we can produce oodles of data that show what you do.  But there are aspects of human being that still defy the data driven trajectory of our society.   Creativity and the play that causes it to bloom are a pain to try and quantify and manage, even with the latest analytically insightful digital tools.  The only way education has managed to make data from a process as complicated as learning is to grossly simplify that learning in order to produce data to feed the machine, but play and creativity defy even this heavy handed approach.  You can grossly simplify learning with standardized testing, but all the testing in the world can’t capture creativity.

The best corporate thinking suggests making a fertile space for creativity and the play that can produce it, but keep management out of it!  Education isn’t as driven by the need to innovate and tends to model its management practices after classroom management anyway.  Education, with its hierarchical thinking and conservative approach, is a much riper environment for data driven absolutism than business ever was.


As a result of this data-driven press, play and creativity are increasingly foreign to the modern classroom.  If it can’t be itemized, quantified and easily compared it isn’t really useful as an aspect of learning; it’s not part of the system.  This is backed up by serious people with data who talk about how a rigorous, intellectually meaningful curriculum can only happen through the mathematical certainty of data-collection.   Less time is given to play and creativity is re-cast as something only geniuses (or the very rich – they’re often the same) have, you can’t learn by practising it.  Students are encouraged to get in step with the ‘real world’ and produce quantifiable material by following transparent and unwavering rubrics, lesson plans and standardized tests.  The data produced in this fish-bowl of honesty allows the education system to accurately and completely (except for the bits we ignore) evaluate student ability and direct them to the most efficient career pathway.  This is handy because career pathways are the only reason schools exist any more.


One of the benefits of a liberal society is the generation of a thriving creative class.  If we can’t compete on the cheapness of human labour (because we don’t the produce quantity of people other societies do), then we can compete on creativity.  Except our data driven approach to learning (and everything else, really) means we are letting creativity atrophy in our children.  


The only people who think creativity is a natural talent you can’t teach are people too lazy to nurture their own.  Those kind of people really like data driven thinking because it means they don’t have to do much thinking themselves.


The answer is yes.  Sir Ken is a popular educational trope.
Teachers are encouraged to watch a video that criticizes
education and then they’re told to prepare students for
standardized tests and grade them with numbers.


Like any hard-won skill, creativity demands commitment to change, metacognitive clarity and growth, and it can be frustratingly non-linear.  One sure way to spark creativity is to create an empty space, the solitude Kaufman spoke of, in which your mind is encouraged to produce its own outcomes.  This can’t happen in an always-on society where your attention is constantly being sought by digital thought merchants who have monetized your attention.  The habits you develop in this brave new world are so orchestrated that your mind quickly forgets how to structure itself; it comes to depend on digitally structured environments.


Another way to spark creativity is play, but not the kind of pre-determined outcome play you find in video games.  Play in those situations is more like the training of a Pavlovian dog; small rewards for correct behaviour.  You win because you’re scripted too.  Open ended play means there isn’t a script to follow, there is no right way to do it.  It means there isn’t a specific outcome, you’re back to conditioning when you demand specific outcomes.  In play-space the outcomes are often unexpected, and can’t be described in win/lose terms (once again, a specific outcome).

Creativity has no required outcomes.  The creative process does produce outcomes, but they aren’t handed down from on high by curriculum, nor do they look alike.  In a class of thirty students (not much solitude there, but you deal with what you’re given), each creative outcome may look so unlike the others that it is nearly impossible to track them all back to the same starting point.  As a standardized test result this is a disaster.  How do you rubric that?  How do you grade creativity?  How do you determine if Billy is 3% more creative than Bob?  The system demands numbers, you better give it them.

We’re here to teach people, not have fun… and intelligence has nothing to do with it!

Fortunately, education has found a scripted way to insert play into learning!  Gamification connects well with educational thinking because they both are directed toward predetermined, specific outcomes.  When educators get all giddy about applying gamification to learning they are harnessing the current digitally driven social trend of attention engagement for their own ends.  They might feel that using this rather nasty process for the good of learning makes it alright, but the ends don’t justify the means in learning.  How you do it matters.

Gamification isn’t play.  You don’t magically produce play by gamifying a lesson plan, though our data driven reflex will happily accept this absurd simplification if it makes us feel like we’re with the times, and producing the same thing that Google and Apple are looking for: engagement.  Teachers and multi-nationals all looking for the same thing?  That’s got to be a good sign.  Our students are trained by financially bottomless digital giants to spend hours connected online.  Education should harness that reflex, right?


You can lead a horse to water, but you can’t make it drink, unless you can exactly measure the horse, the distance it has to travel and its circumstances and then manipulate the environment so that drinking becomes the only possible outcome.  That’s gamification in education.  Data driven thinking would suggest that with enough detail (happily provided by digital multi-nationals intent on not paying taxes while reaping record profits) we can engage a student and invisibly lead them to curriculum required (and usually very specific) learning outcomes.


Societies are societies because they’ve established patterns of thinking that the majority support.  To diverge from that pattern is to move towards the edges of social acceptance.  If you go too far you’ll have passed beyond social norms and become a pariah.  Society is very good at inventing words to describe people who aren’t conforming properly.  Creativity produces new thinking and so creatives tend to be outliers.  A liberal society accepts these creatives more than a conservative one (it is a distinct advantage of a liberal society).


If there is one social mechanism that enforces social norms it’s the public education system.  It has greater social contact with the population than the police or healthcare and focuses on the most pliable citizens (children).  This is generally done as benevolently possible, except when society itself has made some poor decisions, then public education quickly changes from an agent of personal empowerment to a means of indoctrination.  That education seems unwilling and incapable of fostering creativity through play shouldn’t come as a surprise.  That kind of nonsense isn’t conducive to a well organized, radically transparent, data-driven, modern classroom.  You’re not going to produce cooperative citizens if you ignore those societal truths.


Perhaps asking the education system to protect and nurture creativity and encourage play is beyond its capabilities.  As an agent of social conformity education tends to be the anathema of creatives, the lowest point in their creative lives, but if education doesn’t nurture and protect creativity don’t expect Twenty First Century Canadian society to do it.  Our society is becoming more stratified and rigid thanks to increasingly rigorous data driven control.  In a world where our attention is monetized and trained to expect digital frameworks, we are increasingly defined and limited by the data collected about us.  Play is a quantifiable waste of time and the creativity that arises from it is being cast aside.  


Ironically, this is going to cost our society billions.

Naked Concours

The Concours is a naked thing at the moment.  I’m under the fuel tank for the first time since I bought it.  I’m going after the spark plugs, but neither of my imperial spark plug removers would fit.  Kawasaki uses an 18mm metric socket.  Fortunately, Canadian Tire had that very thing in stock.

With the plugs changed it’ll be time to start putting it back together.  I’m cleaning electrical terminals and torquing bolts to spec as I go.


The wheels are off, stripped and cleaned and ready for reconditioning at Fireball Coatings.  I’m hoping to get them over there this week.




What twenty year old Concours rims look like after you’ve had a go at them with SOS pads for an hour.

 
They’re off to Fireball for a two stage gold/candy coat finish.  They look better than they have in years already, I can’t imagine what they’ll look like when I get ’em back!





The stripped bike is letting me get to pretty much everything.  I found the two cut-off gas tank ventilation pipes, which will get properly re-attached again.


Last but not least will be calliper rebuilds and braided metal lines for the rear brake and clutch (which have been waiting until some down time to install – I was loath to do it while I could be out riding).

It will all go back together on new tires and renewed rims ready for the season to begin as soon as the rain washes all the salt and other winter crap off the road.

If I lived somewhere more temperate I’d need two bikes so that I could rotate one out of operation for this kind of work.  Canada obliges by making it miserable outside for four months of the year.
