Kawasaki Concours C14 1400GTR Valve Check Part 2.2 - the cams are coming out

 I was (of course) hoping that the valves would all be in spec, but after a first round of measurements that is (of course) not the case, so this open heart surgery is going a step deeper: the camshafts are coming out. No point in getting in this far unless I sort everything while I'm in here.

Concours 14/1400GTR exhaust valves need to have between 0.19mm and 0.24mm of clearance. The intake valves need 0.12mm to 0.17mm. Looking at the notes below, I'm out of spec (tight) on most of them, making me wonder if anyone has ever been in here before. This one has 45k kms on it but it was semi-dormant when I found it. Most of the mileage was done in its first five years then it sat a lot. Alas, this is probably the case for most bikes.

Looking at this with red being too tight, white being in spec (anything on the edge I made pink), it's clear that C14s get tighter as they go: 

              Cyl 1                         Cyl 2                          Cyl 3                         Cyl 4

    EX  0.18   0.18               0.18    0.19                  0.19   0.19                0.19   0.22

    IN   0.14   0.14               0.14    0.14                  0.09   0.11                 0.11   0.12

Now that I've got a round of measurements, I'm going to do it all over again (that's what the pink notes are at the top of the handwritten bit above - the second round). Measure twice cut once and all that.

I hope to have confirmed everything this week and then I'll order shims to get everything in the sweet spot.  Or not...

It was -35 with windchill (-22C actual) last night. Will be again tonight, so I'm not going into the bloody garage!

Incredible that 5% of one millimeter is the resolution this machine works within, but what amazes me more is that even at a fraction of a millimetre I'm still sticking a bit of metal (like a caveman) in to measure these fine details. Why don't motorcycles make use of the mechanical precision used in car engines for the past quarter century and automatically adjust valves? Good question.

Like a caveman...

The middle ones are tricky to get to and the covers and various plumbing don't help even on the edge cylinders. That Moto Guzzi is looking more and more appealing, though it won't be the rocketship that the Kwak is.

Cam timing cover off to spin the motor and line up TDC for cylinders 1 and 4 which lets you check all the clearances.

Note the mark on the left side of the wheel where the cover gasket goes on - that's your timing mark.

The plumbing over the cams is something else.

The 0.127mm feeler gauge doing the business between the cam and that shim underneath. Replacing the shim with a smaller one puts the gap back in spec.

Using the bent and tapered bits I double checked each space. And will again before I commit to buying shims.

Kawasaki Concours C14 1400GTR Valve Check Part 1 - getting in there

It took 2 sessions about about 5 hours to get
to the point where I can actually remove the
valve cover and check clearances.

This is not the work of an afternoon. To get into the valves on a C14 takes patience. In addition to the advice about staying organized and documenting the process, I'd suggest a 'move the ball down the field' approach. As long as you get a bit more done each time you'll get there, but don't be in a rush and expect to have to come back multiple times. With this approach I didn't get as frustrated as I sometimes do in the garage. It being the middle of Canadian winter with no chance to ride any time soon helps too. Nothing stresses me out more than watching one of my few riding opportunities each year pass me by because I don't have a bike ready to go (though I hope the Tiger is).

I'm finally at a point where I can actually remove the valve cover. I won't lie. Yesterday as I was wrestling the air suction valve gear out of the ridiculously tight space I was wondering who the masochist was who designed this and had a little day dream about cold cocking them.

It's cold in the garage when it's double digits minus outside, even with the heater on, so hand cramps were an issue as I worked stuck fasteners loose. Whoever was last in there tightened the frame bolts well past spec, and even the small bolts holding in the air suction valves were a fight, having to be turned out a quarter turn at a time with a hex key.

Here's the order of operations so far:

Getting Cylinder Head Cover Access

Fairings

I've been into them before for various reasons. They're complicated, but came off with a minimal of swearing.

Once I had them all off access to the valve cover became seeable, but so is the mad amount of plumbing that surrounds them. Getting the fairings off is the tip of the iceberg on this job.

Frame connectors

There are some easy to get ones that you can remove once the fairings are off. 12mm bolts and a 5mm hex that connect the motor to the back and front of the frame. Whenever you think that's enough, Kawasaki Heavy Industries overengineered another piece. This thing really is built like a nuclear sub.

With those off I took the coolant reserve tank out of the way (two 10mm bolts). So far I've gotten deep into this with just 10 and 12mm sockets and 5mm hex bolts (not counting all the fasteners on the fairings). The mechanical fasteners are considerately consistent (unlike Triumphs). I'm going to have to source other fairing fasteners as the cheapo Amazon ones I got all broke when removed.

There are two more frame connectors (because more of everything was how the Conours was designed), one on each side and held in by two 12mm bolts and a 5mm hex bolt. Whoever did these last tightened them to within an inch of their lives, but I got them out. The three fasteners are visible once you've got the fairings off, but once you've got them out the piece itself needs to be slid out from the plastic radiator shroud. I've been warming things up with the heat gun to prevent cracking as I bend plastic and rubber things.

The right side one is easy to access and if you've taken the fairings off, easy to remove. The pipe you see left of the top arrow is the air suction system. Getting that out is a right *@&#er.

The left side one not so much. Note the heat gun blowing warm air on the rubbers and plastics to make things easier to remove (helps with the electrical connectors too of which there are many).

With the frame pieces off it was a matter of removing the pipes and connectors that crowd the top of the valve cover. It's tight in there and even disconnecting electrical components was a real struggle with my non-Japanese sized hands.

You can't fit a 3/8 rachet and bit in that gap, so the air suction valve covers (which you can't even see in this because they're  buried under piles of electronics, coolant pipes and anything else they could stuff in there), need to be removed with tiny quarter turns with a 5mm hex key. Take your time, try not to get frustrated. You eventually get in there.

The ultimate goal it to get the rubber cover over the top of the engine out of the way.

First look at the valve cover, but lots of other gubbins have to come out before I could get that rubber cover folded out of the way.

Air Suction Valve

This consists of a rubber hose going up into the airbox above and connecting not one but two air suction valves (more is always better, right?). These are held in by 5mm hex bolts that nasty to get out - so nasty that I'm heading out to Canadian Tire to look at low profile rachet options (the 3/8 bit on the rachet won't fit in there and doing these by hands is painful).

With the air suction valve(s) - there are (of course) two of them, out you can see the cover, but that cam sensor in the middle of this pic has to come out too (8mm bolt holding it it).

Cylinder Head Cover Removal

• Remove fairings
• Remove Air Suction Valve (see Air Suction Valve Removal)
• Stick Coils (see Stick Coil Removal in the Electrical System chapter)

The stick coils for the spark plugs are in there tight too and require some careful convincing to come out. I'm probably the first person in here certainly since the bike started getting underused ten years ago and possibly ever.

With the Inlet Camshaft Position Sensor removed the valve cover was finally free and came off (out the right side) revealing the fantastically complicated top end.

Next up will be turning the engine around with a rachet and getting an idea of where the valves are in terms of clearances.

Zen and the Art of Motorcycle Maintenance: Patience with C14 Forks

 When I was younger I tended to struggle against time, but as I get older I'm finding that if I slow down and let go of that youthful mania I can see things that get missed and this makes me a better mechanic. Taking on the leaky forks on my 2010 Kawasaki Concours 14/1400GTR also seemed like something too complicated to get into in the garage after the much simpler right-way-up forks on the Tiger (which I get in and out of easily).

Like everything else on the Concours, the front forks are complicated. These would be the first USD (upside down) forks I've done after many right way up forks on dirt bikes and the Tiger, so I went looking for how-tos and was met with a wall of incompetence, both in video making and mechanical ineptitude. So bad were some of them that it made the job seem impossible, but it really isn't.

I finally found Coulda Shoulad Woulda's C14 Fork Seal video and it was just the thing. Yes, I'm starting you 25 seconds in because that's one hell of an intro:

Nicely edited and concise (other than that intro), oh that all youtubers took heed. After watching I believed it possible, so out to the garage I went... and was promptly beaten by the bolts on top of the forks which would not move despite a trip to Canadian Tire to buy the long 24mm socket needed to get on them properly. That socket promptly started rounding them. I suspect whoever was in there last didn't believe in torque wrenches.

Everything I needed for the job was $200 taxes
in on Amazon. The tools seem well made and
worked. The fork seal driver also came in
handy when clamping the fork on the bench.

I applied heat and kept at it, but they would not move, so after lots of sweating and swearing I
stepped away and emailed the local Kawasaki dealer, who I tend to stay away from because whenever I contacted them they give the impression that I've interrupted and annoyed them. A terse reply the next morning that was not forthcoming with the details I needed showed that their service department remains firmly of the mindset that they are doing me a favour whenever I pay them exorbitant fees for service. I finally got out of them that it's $375 to service forks out of the bike and they would only use Kawasaki parts so the seals I'd bought for the job I'd have to buy over again at their markup. A conservative estimate for the job would be $500 in service, parts and taxes, but probably more.

That took me back to the garage where, to my astonishment, the tops came off easily after a few sharp taps with a big socket and some more heat applied. If at first you don't succeed, step away and perhaps after cooling down you've already won. As Classic Bike says, 'heat and patience.'

With the tops loose I was off to the races. I applied some
intentionality to my process and decided to do a fork each day after work rather than trying to do them all at once. This paid dividends because the first fork was a learning process, and when I left it for the night I thought it over and the second one went twice as quickly with fewer problems. Taking your time and moving intentionally is an underappreciated skill in our manic, modern world.

The process of dismantling the forks is fairly straightforward, but requires some jiggery pokery around compressing the spring to get to the internals. Here are the order of operations assuming you've already removed the front fender and wheel:

• Loosen the fork tops while they're on the bike! This isn't easy as the handlebars are in the way. I removed them for access. I also found the metal quite soft. I went out and got a long 24mm socket but it made a mess of them. A well placed vice grip while clamped on the bench did the job better.
• Remove the fairing plastic cover over the front wheel
• Undo the plastic cover at the top of the fork tree (three 10mm bolts) and remove the horn as well which is attached to it
• Loosen the lower fork clamps
• Loosen the upper fork clamps
• Slide out the forks (this was also a pain in the ass - I ended up using a long screwdriver to gently open the clamps a bit to let the forks drop

That gets you to the point where you can start working on the forks themselves.

• Undo the loosened fork tops (if you're luckier than me and the cock womble who was in there last didn't tighten them to death)
• Install your fork compression tools. There are holes in the plastic spacer at the top for you to put a rod in and use the axle mount at the bottom for the other rod

It looks complicated but this is just the fork compressor clamp and a bottom rod provided in the Amazon kit being compressed with rachet straps. 

•  With the spring compressed you will see the nut at the bottom that holds on that top piece
• Pull up on the top piece and you should have just enough space to slip the spring holder piece (also in the Amazon kit) in place. This allows you to loosen the bottom nut and spin off the top

• With that off you can release the rachet straps and remove the spring
• Remove the tube from the centre of the unit. It's fragile so put it somewhere safe and then don't forget to reinstall it (don't ask)
• Empty the oil into a container that lets you see how much is in there. Be sure to work the internals to get everything out

The side with the leak (on the right) had less in it, but both were low. There is supposed to be 550ml of oil in each fork. The dark green stuff on the left looked to be completely different to the brown stuff on the left. I'd guess whoever tried to get into these last couldn't get into one of them and just serviced the one they could - which is nuts!

• Separate the outer fork from the inners
• This lets you pop off the outer seal
• The inner is held in by a retaining ring that's easy to pop out
• Ease the fork seal out of the tube (I applied some heat as the old ones were rock hard - this softened them up a bit and made removal easier

• With everything cleaned up, slide the outer seal on the inner fork making sure it's the right way around
• Install the inner seal in the large (upper because these are USD) fork tube. Doing this while it's separated is much easier than trying to hammer it in when they're attached. I had no trouble getting the inner fork tube on once it was installed (the holes in the inner shaft are chamfered so sliding them on is straightforward
• Don't forget to install the retaining ring after you've got the inner seal in (letter side down because these are USD - the 'open' side should be facing the oil).
• Install the inner fork in the outer with new seals
• Put the spring back
• Put the plastic bit on top and rebuild your spring compressor (don't forget the metal cap)
• loosen the nut on the threaded inner rod and use a matching bolt to give you something to pull it up with when you've got it back together
• Compress it all down again with the ratchet straps
• Pull the top using that bolt you put on and slip the metal piece to hold it in place
• Remove the bolt you used to make it reachable and tighten the nut on the inner threaded piece that's held by the tool you slid in to hold it compressed
• Insert that inner rod you put aside earlier (no, really, remember to do that)
• Screw on the fork top piece and tighten to the lower nut to it
• Double check that you've put all the bits back (inner rod, metal cap on top of the plastic top piece)
• Press down on the compressor that's in the holes in the plastic and slip the retaining metal tool out
• Release the rachet straps
• Put 550ml of fork oil in each. I used 15 weight Maxima
• Work the fork to get any bubbles out (I also let them sit overnight to let things settle)
• Spin the outer fork onto the now attached fork top threaded piece
• Reinstall the forks. The lower bolts said 30 Nm but they still gave me headaches when one sheered in the tube. I stepped away and sorted it out the next day when I wasn't annoyed.

This seems like a handful but if you work your way through it one step at a time it all makes sense. The first fork took me a couple of hours to take my time going through. The second one took less than an hour. Once you've done this once you'll feel able to do it again. Give Coulda Shoulda Woulda's video a watch and you'll have what you need to get it done... and be patient!

Yep, that's a broken lower fork clamp bolt sheered off inside the housing. I ended up getting it out by getting needle nose pliers on the end sticking out and spinning it out that way. This job fought me at every step, but it's all back together with matching (clean) oil in both forks and everything one tightened (to spec) not too tight. One tight, not too tight...

When things went wrong (and the did... often) on this job, I got myself to a reasonable stopping point and stepped away for the day. When I came back the seemingly insurmountable problems (stuck fork tops, broken bolt in the lower clamp) all seemed to have answers.

The old seals were rock hard. I'm curious to see how nice the forks feel with the new ones.

Vice grips did a better job on top fork removal than the specially purchased long 24mm socket did. Applying heat was easy in the vice and the seal driver tool was handy for clamping the fork off the bike.

Removing the handlebars didn't help with loosening the tops of the forks. Hat and vice grips on the bench finally did the trick. I'm going to try the handlebards without the bar risers for a while and see if it feels ok.

***

I've had the bike out a few times and the feel in the front end is fantastic. I'm getting feedback like I've never had before and it's leading to a much more enjoyable ride, both when taking corners and navigating poor pavement; transformative isn't too strong a word.

When I put it back together I dropped the forks in the front tree about 1/4 of an inch, so the bike feels a bit more on the nose. The other thing I did was take the risers out of the handle bars. These had me more upright in the seat, but I left the 'angle wedges' in and the steering feels more immediate than it did without really affecting my geometry. 

This servicing has been well worth it, but so has the opportunity to reconsider the geometry on the front. Right now the GTR1400 is as perfect as I've ever had it, and just as it's about to hit 45k.

Sail Away: First Long Ride on The Kawasaki Concours 14

First long ride with Big Blue/Nami-Chan (not sure what its name is yet) today up to Georgian Bay to listen to the water.  For a kid who grew up by the sea living in landlocked Southern Ontario wears on me so sitting by the shore listening to the water lapping on the rocks calms my permanent sense of dislocation.

Thornbury Harbour, Geogian Bay, Ontario - Spherical Image - RICOH THETA

What's the Concours 14 like to ride over distance?  It's a very comfortable long distance machine. Compared to the Tiger it's smoother, significantly less vibey and quieter.  This isn't necessarily a good think because riding a motorbike isn't always about comfort - sometimes you want it to beat the shit out of you.  What is good is that the 1400GTR is a significantly different bike to ride than the old Triumph Tiger, so both fill a different need in the bike stable.

The Tiger (when it works perfectly which isn't often recently) is a capable off roader on trails and fire roads and lets the wind pass through you since it's practically naked, which is both exhausting and exhilarating.  After the long ride today the abilities of the Kawasaki are much more clear.  The only nagging issue is that my backside has gotten used to Corbin seat engineering and the Kawasaki stock saddle just isn't up to the job, but otherwise the bike is a revelation.  Effortlessly quick, smooth and surprisingly agile in the corners, though you can still feel the weight carries but it carries it low.

Windshield down, lots of airflow, a great view
and the bike feels more likes sports-bike.

For the first time I adjusted the X-screen modular MCA Windshield to its maximum length and it did an astonishing job of protecting me at highway speeds.  So much so that I barely closed the Roof helmet on the ride.  The pocket of air it creates is stable and the wind noise so much less that it's just another aspect of this bike that'll let you do long miles without exhausting yourself.

Ergonomically, the windscreen also does something smart for airflow.  If it gets hot you can lower it to the point where it almost vanishes.  This pushes a lot of air through your upper body and supports your chest from leaning on your wrists.  I hadn't put much stock in an adjustable windshield but it not only changes the look of the bike, it also changes its functionality too.  On long rides changes in airflow keep you comfortable and focused.

Windshield up while you're making tracks
on less demanding roads and you're in a
quiet bubble of air that lets you go for miles.

The bike itself seems to manage heat well which the old ZG1000 previous generation Concours 10 I had did not (it used to get stupid hot!).  If stuck in traffic, even over 30°C pavement, the temperature gauge never went above half way and the fans haven't needed to come on yet.  The lack of wind-flow over my legs on hot summer rides may yet be an issue though, the fairings are too good.

The other complexity piece of the C14 that I wasn't sure I was interested in was the digital dash but that too is proving valuable.  I'm no longer guessing what gear I'm in based on revs and road speed so I'm no longer trying to shift into a non-existent 7th gear, which happens often on the Tiger.  Though the 1400GTR revs so low while in 6th/overdrive (3200rpm @ 110kms/hr) that you wouldn't be looking for another gear anyway.

Mileage has been a concern on this smaller-tank/worse mileage than the Tiger bike.  The Kawasaki's 22 litre tank is 2 litres smaller than the Tiger's which also gets 10+ more miles to the gallon.  I'm going to fill up a spare 2 litre gas canister and run the Kawasaki for maximum range a few times to see what this C14 can actually do.  When I fill it up it cheerfully states it'll do 360km to a 22 litre tank which works out to 38.5mpg or 6.1 litres per 100 kms.  The display shows when you're maximizing mileage so a long ride without wringing its neck to see what mileage it can achieve is in order.  If I can get 400kms out of a tank that'll put me up into the mid-40s miles per gallon, which would be a good return on such a heavy, powerful machine.  The range indicator jumps around to the point of being meaningless and then cuts out when the bike gets low and you need it most - not the best user interface there, Kawasaki, but I've heard there may be a wiring hack to stop that from happening.

So, after a 290ish km run up to Georgian Bay and back I'm very happy with the bike's power, which is otherworldly, it's comfort is good but I'm looking at seat improvements.  I've heard other larger riders put peg extenders on so there is a bit less flex in the legs, which might eventually happen.  Many people also put bar risers on them so the bars come towards you a bit more, but I'm finding that I'm able to move myself on the seat to get a more vertical or more sporty riding position depending on what I'm doing, so bar risers aren't on the radar.

I did pick up a spare fuel bottle that fits nicely in the panniers (which take a bit of getting used to for all the keying in and out but are huge and don't affect the bike at speed at all).  Next time I'm on a long ride I'll top the spare bottle up when I top up the bike and then see how far I can push the range.

It was an uneventful ride except for one incident.  Leaving Thornbury harbour the 360 camera fell out of my pocket onto the road.  I pulled over quickly and safely and then ran back to scoop it up off the road.  There was traffic back at the lights in town just starting to move and 3 cyclists riding on the side of the road coming towards me but still some way away.  I ran out to the camera, scooped it up and ran back to the curb and almost took out one of the cyclists who had elected to accelerate towards me rather than giving me space to get off the road.

She yelled, "bike!" and I made a dexterity check that had me dodging around her rather than taking her off the bike.  They kept going but I was left standing there wondering what the thinking was.  You see a guy duck out into the road to pick something up so surely you would ease up a bit and let him do what he needs to do to get out of the way - but not in this case.  From what I've seen of cyclist's approach to sharing the road, I imagine that I'm entirely at fault for that.  It left me shaking my head at their thought processes.
