Mechanical Satisfaction


The Concours carburetors weren't snapping back when I released the throttle. Everything worked, but they wouldn't close on their own as they should. I removed the carbs, reset the butterflies so they all closed properly and replaced a bent spring. With everything lubed up and working freely, I reinstalled the carbs and ran the throttle cables over and along the top of the frame rather than around the side, trying to have the throttle cables address the carbs as perpendicularly as possible.  With the cables properly tightened, the carbs snap shut when the throttle is released, as they should.


My to-do list on the Concours is down to a rebuild of the master break cylinder.  The part isn't expensive.  I'd purchased a set and did it on the Yamaha XS1100 I had before, so the Concours should be pretty straightforward.
I also have to sort out a rear light and body panels for the back end.  I'd asked if they could be done at school in the metal shop, but asking for work to get done there seems to result in it disappearing down a hole.  I'd rather do the work myself anyway.  The plan is to form the panels for the back end and find a rear brake light with indicators built in and wire it in to the back end.


The last job is going to be reworking the radiator reservoir to somewhere around the battery box.  With that done, in theory, the Connie will be ready to begin test riding the kinks out.




Follow-up:  rear brake lights were found on ebay - let's hope they arrive this time.

If they do then ebay is a more dependable shipper than the Amazon Marketplace, which seems pretty bizarre, but there you are.

Naked Connie: 3d modelling customized motorcycle bodywork

I've re-3d-scanned the stripped down ZG1000 Kawasaki Concours in order to better work out what the rear lights will look like.  You can wheel in and out and manipulate that model below with a mouse.  The scanner did a bunch of software updates which led to a much higher resolution 3d image.




I modelled it with the stock seat on with an eye to taking the pillion seat off and building a very minimal back end.  With some careful cutting I'll be able to use the seat dimensions to figure out how best to render the rear light assembly.  I've been doing 2-d drawings but they don't deal with the 3d complexities of the real thing.  I'm hoping this solves that.




Using the 3d scanner with cardboard body panel templates gives you a pretty good idea of how it will look when it's done.




As far as electronic parts go, I think it's time to get the lights sorted out.  At the moment I'm looking at some integrated LED head and tail lights to minimize stalks sticking out of the bodywork.

Naked ZG1000 Custom Inspiration

Some Andy Warhol-esque ZG1K shapes to get a feel for what the bike will look like:


I'm still thinking purple with asymmetrical gold racing stripes, but that might change again.


Cardboard cutouts of the side panels I need have gone to the metal shop.   I'm going to prototype some 3d models on the printer at work and see what various shapes look like before doing the final cuts in metal for the rear section.


While that's going on I've got to get the front cowling figured out, which is what led to the video...

Fury Project: final drive & body panels

With the snow finally falling I've had time to start into the naked Concours project.  The first thing that needed addressing was the final drive unit which was leaking from the inner seal.  When the Clymers manual says you can do it but it's a big pain in the ass, it's best to have a practised hand do the work.  I took the unit off (easily done as it's held on the drive shaft by four bolts) and loosened all the fasteners on the inner plate.  

Two Wheel Motorsport, my local Kawasaki dealership, said they could do the work and estimated two hours of shop time and a twelve dollar seal.  I dropped off the unit and got a call back four days later saying it was done.  It was a nice surprise to find that the work took less than an hour and my $250 estimate was suddenly a $120 bill.  You hear a lot of negative talk about dealerships but Two Wheel did this job professionally and quickly, and then didn't overcharge when they easily could have.

I cleaned out the shaft drive end and re-greased everything.  Reinstalling the unit was easy and straightforward.  With the grease holding the spring in place I was able to simply slot the drive unit onto the shaft splines and re-torque the four nuts.  Everything went together smoothly and the drive feels tight and positive.

Since this was the only mechanical issue with the Concours I was able to begin thinking about the customization side of things.  With over 100lbs of plastic and metal removed from the bike I needed to start thinking about how to minimally dress this naked machine in order to cover up the plumbing and electrics.  Having a metal shop at work means handy access to fabrication tools.  Our shop teacher is also a Concours owner and is eager to help with panel building.  He suggested I do cardboard cutouts of the pieces I need and then we can begin the process of creating metal body work.

Body work craft day in the garage.
Doing the cutouts is tricky even in cardboard.  The left side cover goes over some electronics including the fuse panel and needs to bulge outward in order to contain all of that.  The right side is more straightforward but still needs cutouts for the rear brake wiring and rear suspension adjuster.  I'm curious to see how close the metal cutouts come to the cardboard templates.

The shop at school has a plasma cutter and we should be getting a laser engraver shortly.  With such advanced tools I'm already thinking about engraving panels.  Collecting together a bunch of line drawings of iconic images and sayings in a variety of languages would be an interesting way to dress up the minimal panels on this bike.  If the laser engraver can work on compound shapes I might drop the gas tank in there and engrave Kawasaki down the spine of it where the gold stripe will go rather than looking for badges or decals.

I enjoy the mechanical work but now that the Concours is working to spec I can focus on the arts and crafts side of customization.  Next up is trying to figure out how a minimal front panel that contains the headlight and covers up the electrical and plumbing at the front will look.

ZG1K: Customization, Inspiration & Aesthetics

Graphical thoughts on the ZG1K customization...

I'm still working through the proportions of a naked Concours.  It isn't a delicate device...

In spite of the colourful nature of the bike, it's a muscular heavyweight.
Inspirations for this build revolve around 80's sport bikes and naked streetfighters.  I grew up in the '80s and have a thing for fully faired race bikes with blocky rear ends.  The big, bulky Concours' tank lends itself to a strong, balanced back end.

The paint's already coming off the tank.  I need to figure out how to make a rough 3d outline of the rear body work (cardboard, wood, thin metal?) in order to begin getting an accurate sense of how the back end will look.  If I can get handier with 3d editing software I'll 3d print a few various prototypes first (maybe scan it with cardboard panels in place).

The front fairing will be a minimal street-fighter type of thing.  I wanted to go with a bikini fairing, but it's a bit too delicate for the big shoulders of the Concours.  Monkeying around in Photoshop has gotten me this far:



But this is more of a sculpting thing than a pen and paper thing.  I need to make some cardboard outlines and see what feels right in 3d (Close Encounters style).

The Mike Tyson/heavyweight feel of the Concours means I'm thinking more melee fighter than I am lightweight and delicate.

ZG1K: A Customized Kawasaki Concours

I've stripped down the Concours to the bare bones.  From there I intend to build it back out into a cafe-racer/naked streetfighter.  A barebones ZG1000 Concours looks pretty butch:

The brown seat will sync with
a crimson stripe.  Were money
less of an issue I'd get it custom
upholstered to run the stripe all
the way through.
The back end is going to get tidied up and topped with a cafe style brown leather seat.  I'm also researching LED light systems that will be all but invisible under the seat until they light up.

The front end is going to get a basic/minimalist light cover and a light that has indicators built in for a clean look our front (no indicator storks poking out).  The front fairing and light will be mounted to the forks.


Stripping on the Ducati Monster is
a thing of beauty.
As for paint colours, I'd like to try and take the tank back to metal and then have a crimson stripe running over the minimal front fairing, along the tank and across the minimal rear body work.  An asymmetrical design with a thick centre strip and a thinner stripe off to the right is what I'm currently thinking, though I'll see what works as the bike comes back together.  If the tank is too rough I'll redo it red with a gold stripe that matches the wheels.  Now that I say that, it might be what happens anyway.


I'm going to use the Structure Sensor scans to map out body work in 3d.  I'm also going to make use of a Dremel 3d printer to print out scale replicas of different body configurations.  These are some screen grabs of the 3d scan (which you can see at the top).











The massive twin exhausts might get modified, but right now I'm enjoying the big-guns look they have, so I'll probably be keeping it.  They help visually balance a bike that looks otherwise top heavy with that massive gas tank.


First go at a logo - I think I'm going to have to find the Kawasaki Heavy Industries
logo for this heavyweight streetfighter.
