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.

Rainy Day Carburators

A cold, rainy Saturday had me break down the carburetor on the Yamaha XS1100.  A Triumph Spitfire and Mercury LN7 owned as a teen made me pretty handy with carburetors.  In addition to multiple rebuilds I also got handy at jury rigging manual chokes thanks to the utterly crap Ford Escort carb set up.

The beautiful Mikuni unit on the Yamaha looks like a piece of industrial art in comparison to the pedestrian Triumph and Ford carbs, unfortunately it's seized.  After breaking down the top end I soaked it and freed up the seized throttle body.

The next to-do with the Yamaha is to clean up the gas tank and then reassemble the fuel system.  The engine isn't seized and spins easily, so I think I'll have an easy time firing it up for the first time in years (knock on wood).

Here are some pics of Mikuni's Yamaha masterpiece:

The throttle cable wasn't playing nice even after taking apart the handle bar - so into the carb I go...

The Yamaha XS1100 engine block with the carbs off - it got the Warhol treatment....

Like everything else so far, the internals look to be in good shape on the old (35 year old!) Yamaha

Tiger Brains

The other day I was once again going over the details on the Tiger after taking the tank of for the billionth time.  Even though the stock pipes for the vacuum controlled idle system for the electronic fuel injection hold vacuum when I test them, I can't test that when they're on the bike, so they might be leaking where they join.  I happened to have some fuel line in the right size, so I've taken out the Triumph hoses and put these clear ones on instead to isolate another possible point of failure.

Once I got them in I fired up the TUNEBOY software and figured I'd run the idle control system test since it would move the plunger up and down and with everything off I could check to see that it's all working as it should,  except the ECU wouldn't connect to the computer.  I've done dozens of TUNEBOY adjustments now and know how the bike syncs with the PC over the serial port, but it wasn't connecting.  While trying some variations I turned the ignition on on the bike and the ECU made unfamiliar popping noise, and then none of the dash lights would come on (the running lights still do though).  The ECU no longer clicks off when the ignition is switched off either, which suggests it's not coming on either.

The intermittent nature of this failure always made my ass twitch in terms of it being electronic rather than mechanical.  Mechanical failures tend to be more consistent and easier to diagnose, and I've replaced everything around the idle control system now, so unless Triumph sold me a dickey idle control motor, which seems unlikely since the first one lasted 17 years and did over seventy-six thousand hard, Canadian kilometres and survived seventeen -40°C Canadian winters.  Assuming all the new parts are working as they should, an ECU that was losing the plot is as likely a culprit as anything else I've been chasing, and now it seems to have popped entirely.

So what do you do when your old Triumph's bike brain loses the plot?  Get another, I guess.  Used ones seems to be extraordinarily expensive and look to be in rough shape out of US used parts suppliers on eBay.  And for some reason they're charging twice what European suppliers are for shipping.  With that and the fact that The States seem like they're on the edge of a civil war, I think I'll be looking to the dependable Germans who have COVID19 well managed for a replacement Tiger brain.  If I'm thinking that, I wonder how many other people are avoiding business with the US right now.

But before I go that far, I'm a G.D. computer engineering teacher, so I'm hardly going to let an ECU go in the bin without having a go at it first.  If this is a short or something simple, I can solve that easily enough.  If nothing else I can see how the ECU is set up architecturally, but more often than not I'm able to get electronics I have to open up working again.  Time to flex my soldering prowess.

The most frustrating part about this is that I may well have solved the idle problem with replacement hoses, or maybe I didn't.  Maybe I chased down all of these hoses and parts for nothing and it was the ECU losing the plot all along.  Electronic Fuel Injection (EFI) is a wonderful thing, but the early systems were fragile.  There a lots of posts online about early Triumph EFI headaches, and I've added to them.

Guy Martin does a good special called The Last Flight of the Vulcan Bomber.  They grounded the last of these nuclear bombers in 2015 because they no longer had the expertise and technology too keep them safely air worthy.  In the show Guy talks about why there are plenty of older planes like Spitfires still flying when the Vulcan has to be grounded.  He says the Spitfire was made from bicycle parts you could fabricate in a shed, so they're relatively easy to maintain.  The Vulcan was an industrial machine with early electrical and electronic systems that were many times more complicated.  He goes on to talk about how the Vulcan looked like it came from another planet when only seven years earlier an Avro Lancaster was the state of the art.  There are performance advantages in these leaps forward, but there are also maintenance headaches that mean these early jets will never fly again.

Early fuel injected bikes are a lot like that Vulcan - they can do things earlier bikes can't like get better mileage, not need parts changed to ride at altitude and generally require less maintenance.  I just fixed up one of the last carbureted bikes, a 1997 Honda Fireblade, over the winter.  EFI was around then, but Honda wisely went for highly evolved carburettors rather than new, fragile and poor performing EFI systems.  I rebuilt the carbs, which are a complex but highly evolved four-carb set, and the bike runs like a Swiss (or rather Japanese) watch.  The EFI on the Tiger did the job without any attention for 17 years and seventy-six thousand kilometres including two rides into the Rockies - something no carburetor could do, but when it finally broke, boy did it break.  It's things like this that will make these first generation EFI bikes rare in the future.  Like the Vulcan, they're so complicated and difficult to maintain when they go wrong that they'll get retired from service where an older, simpler bike might still be fixable.

Wahay!  A new ECU is two-grand, AMERICAN!  That's over $2500 Canadian!  The whole bike cost me three grand.  See what I mean about the costs of keeping emerging, fragile old tech active?

COVID19 Rapid Restoration: Fireblade for the first time since Obama was President

The Fireblade project has come together nicely thanks to the strangeness we all find ourselves in with the COVID19 pandemic.  With a suddenly extended March Break, I was able to sort out the fairings, get the LED indicators wired up and finalize all the plumbing for fuel delivery.  It was all fiddly, last minute stuff, but with the time in hand it was easy to sort.  The adjustable indicator relay got wet when I cleaned up the bike which prevented the LEDs from flashing, so it got waterproofed and sealed.  The first ride was enlightening...

That's the first time it's been running since Obama was in office.  It's a very different thing from other bikes I've owned.  I'm a big guy and 50 years old, but the yoga helps with the flexibility needed to ride this machine.  The foot pegs are significantly higher than anything I've owned before, and I'm leaning forward over the gas tank in a much more prone position than on the Tiger.  I was very conscious of the clip-on handlebars and the lack of leverage you have when cornering - steering on an adventure bike is much easier because you've got big, wide bars that offer a lot of pull.  The Fireblade was so much harder to turn (the weight of leaning forward doesn't help) that I actually thought the steering was obstructed, but it wasn't, it's just a lack of leverage.

After the first ride I thought, 'this thing is virtually unrideable!'  But as I was working out the details and getting used to it the riding position started to make a different kind of sense; I think this bike can teach me things.  The centre of gravity is so low, and the bike is so much lighter (over 40 kilos!) than my Triumph Tiger, while producing thirty more horsepower, that it's a significantly different riding experience.  I wouldn't want to go touring with it, but for an athletic afternoon out on nearby twisty roads, it's the instrument of choice.

The inline four cylinder 918cc engine makes a glorious noise when you crack the throttle, and the 'Blade is responsive in a way that makes any other bike I've ridden feel heavy - that's something I could get used to.  On subsequent rides I got my legs into the cutouts on the tank and once locked in place the whole thing suddenly clicked.  It'll take all the core work I've got to work with it, but this machine expects you to take riding as a sport rather than a leisure activity.

So far I'm at $1200 for the bike delivered, $250 in taxes and registration, $280 for a replacement carburetor which I cannibalized with the one I had to create a working one (if anyone needs late 90s CBR900 carb parts, get in touch), and another $200 in parts that included the shop manual, oil and filters and the LED lights.  All in I think I'm at about $2000 on the road and running like it's new again.  Looking up CBR900RRs online, a one a year older model with three times the kilometres is on for $2800.  Low mileage mint ones are going for $6-7000.  I think I could sell it in a year for a thousand more than I put into it.

When the pandemic happened here just before March Break I took home the Structure Sensor 3d scanner and did some scans, which is what you're looking at here...

It's very satisfying to bring the 'Blade back to life.  Now that the mechanicals are in order I'm thinking about racing stripes.  Amazon has some well reviewed ones on for a good price, I'll give them a go rather than painting them on.

Unfortunately I'm stuck for getting the bike safetied and registered on the road because everything is closed at the moment.  I'll spend the time making sure everything is order and looking to the aesthetic details and hopefully I'll be able to put the bike on the road when we put society back in motion again in May.

Five Years: Diversifying Motorcycle Experience and Finding Balance

After the first year on two wheels I began thinking about more challenging motorcycle projects that would diversify my experience.  Starting in year two I did my first away motorcycle ride, renting scooters and then a BMW around the southern end of Vancouver Island - that led to my first article being published in Motorcycle Mojo and gave me a lot of insight into variations in motorcycling.

In addition to pushing my riding experience in daring new directions (like riding two-up with my son on an unfamiliar bike on one of the most challenging roads in Canada), I also began looking for a bike that needed more than just regular maintenance to operate... a bike that needed me.

I discovered just such a thing toward the end of that riding season, a long dormant Kawasaki Concours that we had to cut out of the grass it was sitting in.  Something that old (twenty plus years at the time) had a lot of perished rubber on it, and when I finally got it up to temperature it also had a sizable oil leak.  The winter was spent getting a new oil cooler and lines, replacing a lot of rubber bits and otherwise getting this old warrior back on its feet again.

The Concours not only got me moving mechanically, but it also offered a real blank slate, something I've since realized is only available on well used bikes (unless you're loaded and like to pull apart new things).  I'd enjoyed the aesthetic restoration of the Ninja and was looking forward to doing the same thing on the Concours.  Getting an old bike and making it not only usable but unique looking has been one of the highlights of my motorcycling career to date, and a trend I intend to continue.  It's something that my current too-nice Tiger doesn't offer me.

The Kintsugi Concours became my go-to ride and the Ninja became my first sold bike.  It was difficult to part with something I'd developed such an emotional bond with.  I can understand why the people with the space and means hang on to every bike they buy.  Having beaten the selling a bike emotional roller coaster, I immediately went looking for another, but it took a while to finally find the right thing, and in the meantime the old Concours suddenly became less than dependable.

A KLX250 that couldn't do 100km/hr with me on it made me feel like I was overly exposed and under-powered while riding on the road, though it was a deft hand off it and gave me my first real off road experiences.  I held on to it over the winter and when there was finally a break in the never ending Canadian snow I thought this is the moment the KLX will shine, on dirty, just thawed roads - except it wouldn't start.  It was a lot easier to sell because I'd never fallen in love with it.  Getting $400 more than I bought it for didn't hurt either.

Later that summer I made my next motorcycle buying error and stumbled into an old Yamaha XS1100 sitting on the side of the road.  I ignored the three strikes against it (non-runner with no ownership being sold by a gormless kid) and purchased it anyway; I won't do that again.  I got lucky on the ownership - it was within a whisker of being a write-off and had a long and difficult history (I was the thirteenth owner!), but I was able to sell it on after sorting the ownership and just broke even.  In the process I stumbled onto a balancing act I hadn't considered before.

I love riding older bikes I wrench myself, but they aren't always ready to ride.  When the otherwise dependable Concours wasn't and my only other choice was an ancient Yamaha I'd only just freed up the brakes and carbs on, I found myself with nothing to ride as the cruelly short Canadian motorcycling season began.  I'd gambled too much on being able to keep the old bikes rolling.  With riding days so valuable in the Great White North, that wasn't a viable approach.

I still had most of the money from the Ninja sitting aside and my wise wife said to just focus on getting something newer and more dependable.  Maintaining that balance means having a riding ready bike and a project bike, and not messing up that equation.  To further complicate things, I'm a big guy so I needed a bike that fit, and my son was getting bigger every year and loved coming along, so I needed a bike that would fit us both.  Being the onerous person I am, I didn't do the obvious thing and buy a late model Japanese touring bike that runs like clockwork.

My daily rider suddenly popped up on Kijiji but it ended up being the most emotionally driven purchase yet.  Instead of a sensible five year old, low mileage Kayamonduki, I got bitten by a thirteen year old Tiger.  It was European, over budget, too old and with too many miles, but the owner was a young professional (nuclear operator!) and from the UK and we had a good, straight up chat about the bike.  I was honest about my position (the Tiger was out of my league but I loved it and wanted it), and he was straight up with his position (he was about to take it in to trade for a new Triumph at the dealership and even my lower offer was much better than he would have gotten on trade in).  I ended up feeling like I stole the bike for over a grand less than he was asking and he got more for it than he otherwise would have.  It was an emotionally driven purchase with a lot of rational oversight.

With all that good karma the Tiger has turned out to be a special thing.  I was only the third owner.  In thirteen years it had averaged less than 4000kms/year, and on two years the first owner had ridden it out to Calgary and back (seven thousand plus kilometres each time).  It had been power commandered (that had never come up in the purchasing discussions), indicating that the original owner had really fawned over this bike.  The guy I bought it off wasn't very mechanically minded and it hadn't had much in the way of regular maintenance, but then he hadn't used it much.  Within a couple of weeks I'd gotten it safetied, done all the maintenance and given it a good tuning - it has run like a top ever since.

It's an older, European bike, but fuel injection and a resurgent Triumph Motorcycles Co. using the latest manufacturing techniques means it's not a bonkers choice as a daily rider.  On the second year of ownership it fired right up after hibernating under a blanket in the garage, and it did again this year.  I've fixed some dodgy, plastic fuel connectors on the tank, changed the tires and done the fork oil and other fluids along with the chain, but other than the fuel fittings, it's all been regular maintenance.  The Tiger has been such a treat and it's such a rare thing (I've only ever seen one other) that I can't see myself letting it go.

Meanwhile the Concours became the project bike, but since I wasn't depending on it, the project took on new dimensions.  I stripped the old fairing off and ended up with a muscle bike like no other.  I've experienced some drift with this project and I think when I get it to a riding level I'll sell it with the aim to make my money back on it (shouldn't be too hard considering what I got it for).

I think the drift comes from biting off more than I can chew as far as tools I have on hand and time and a comfortable place to work.  If had welding gear handy and could do the fabrication I needed, I think I'd still be be pushing for an edgy completion to the project which has taken longer and has been more involved than I initially planned.  The heart is willing but I'm too tight money and time-wise to chase this big of a thing.  In the winter it hurts to go out in the garage and work on it and in the summer I'd rather be out riding.  Future projects might be more of a Shed and Buried/SPQR approach where I can get a bike sorted and back on its feet again, have some fun with it aesthetically and then move it on without losing any money on it.  Making enough on each one to keep me in tools and pay for the process would be the dream.

The sophomore years of motorcycling have been about pushing into more challenging riding opportunities.  From riding Arizona (another one that got published), to going to the last MotoGP race at Indianapolis to circumnavigating Great Lakes and Georgian Bay, I've gotten more and more daring and gone further afield with each season.

These years have also been about dusting off and expanding my technical skills and have seen me do everything from oil coolers to complete carburetor rebuilds.  The garage has gotten better and better in the process, though it's still bloody cold in the winter.  If I could find a solar powered heating system for the space I'd be a happy man.  If I had a heated, insulated work space about twice the size, I'd be even happier.  The other side of the coin is riding opportunities.  Living somewhere where you can't ride for 3+ months of the year isn't conducive to building saddle experience.  I'd be happier if I lived in an all year riding opportunity - or at least if I had access to such places over the winter here.

20 hours might have gotten me able to manage the basic
operations of a motorcycle - the Conestoga course was a
weekend with about 4 hours on bikes each day, then some
very tentative rides in the neighborhood got me to 20 hours.

At five years I feel like I've put a lot of time into improving my rider's craft.  I've also spent a lot of energy getting the rust off my mechanical skills.  What I most wish for the next five years is to maintain my hunger for more motorcycle experiences.  I'd like to try  a wider range of different bikes and types of riding and find a way to dig even deeper into mechanics.  This year I'm hoping to take an off-road training course.  In the future I'd love to find the money and time to take track riding, if not to pursue racing then at least to explore riding dynamics at the extreme end in a controlled environment.

If you put ten thousand hours into something you've developed a degree of expertise in it.  In each season I've tried to beat ten thousand kilometres of riding (and succeeded) before the snows fall.  Those fifty plus thousand kilometres have probably had me in the saddle for over a thousand hours and I've easily spent that again in the garage doing repairs and maintenance.  If feel like my motorcycle apprenticeship is well underway, I just need to keep finding ways to feed that expertise.
