What's a Kawasaki GTR1400/Concours14 like to ride? NUCLEAR SHINKANSEN!

I picked up this Concours14 (or 1400GTR or ZG1400 depending on what market you're in) back in April for $5500CAD.  It had been sitting for some time and was full of spider nests.  I got the safety sorted yesterday and got the bike licensed and on the road today so we're ready to finally make some tracks with this thing.

What's it like to ride?  I've owned more Kawasakis than any other kind of bike and their engines have always been what makes them special, and this bike is no different.  The 1352cc inline four at the heart of the Connie was identical to the ZR1400 hyperbike's motor back in the day, and it shows.

On my first ride I pulled out to pass a truck and it was behind me almost too quickly to process.  I'm coming off owning a late 90s Fireblade so it's not like I'm inexperienced with quick bikes, but the 1400GTR not only has the horsepower but also has the torque to back it up.  Where the 'Blade was staggeringly quick (and light), you had to wind it up to make it go.  It felt like a light but not overpowered machine at sub 6000rpm engine speeds.  At 6k it became seriously quick and if you were brave enough to chase the 13,000rpm redline the bike turned into a total head case.

You don't need to wring the Kawasaki's neck to make astonishingly rapid progress.  It weighs over 100 kilos more than the Fireblade but makes over 30 more horsepowers and pound-feets of torque; it doesn't feel heavy, which is an amazing accomplishment for a bike that can carry over 500lbs, has shaft drive and feels like it's ready for five hundred mile days.

It's not telepathic in corners like the 'Blade was, but that bike's focus was so singular that it made everything else difficult.  The 1400GTR does a good job of cutting up corners, hiding its 300 kilo weight well, but then it can also ride all day, still hit 40mpg and carry two up with luggage.

Ontario makes you buy a vehicle history when you buy a new bike but I don't mind because it offers you insight into the machine's history.  This bike is a 2010 model but it wasn't first licensed for the road until 2014 (!) meaning it's only been rolling for seven years rather than eleven.  The first owner had it two years and then sold it on to the guy I got it from.  He rode it for a couple of years and then parked it after it tipped over on him in a parking lot (hence all the spider nests).

The prolonged park is what shrank the seal in the clutch that I've since replaced.  The drop also stopped the windshield from moving but both things have been solved now and this Concours, with only 32k on the odometer, is finally ready to do what these bikes do best:  make big miles.  One of the guys at our local dealership is a Concours fan and got his over 400,000kms, so these things have staying power as well as horsepower.

I'm looking forward to getting to know this nuclear shinkansen (Kawasaki Heavy Industries makes bullet trains too!) better this summer.

Triumph Tiger 955i: checking your motorcycle alternator and replacing a regulator rectifier

I tested the Tiger's alternator today. This is found under the round cover on the bottom left side of the bike.  I've lined up a MOFSET regulator/rectifier for the Tiger after some concise and clear advice from PSPB's FB forum where you always get clear advice instead of a bunch of internet mouth-breathers jumping in with what they don't know.

The Triumph OEM reg-rectifier isn't available and costs nearly $400 while also being an inefficient silicon controlled rectifier (SCR) shunt type reg-rectifier.  The one coming is a metal oxide semiconductor field effect transistor (MOSFET) based unit that is both faster and more efficient both thermally and in terms of providing steady voltage to the battery.  

With a new reg-rectifier coming, I took the advice on PSPB's FB forum and tested the alternator.  To make sure you're getting clean AC power you test the three wires going into the alternator for resistance (they should all show similar resistance between them).  The result was a steady 0.5ohms across all the connectors, which bodes well.

The final test is to make sure nothing is showing infinite resistance to ground on the bike.  Once again the alternator in the bike showed good wiring with no infinite resistance to ground on any of the wires:

The next step will be to wire up the new reg-rectifier when it gets here (should be early next week) and then see how things go.  The one I was able to find is wired for my specific Triumph (though Triumphs and Ducatis from the era both seemed to share the same unit).  With the new reg-rectifier wired up I should be good to go with the Tiger again and hopefully the (new over the winter) battery isn't having to carry the bike like it was and I won't have the stalling issues that have been plaguing me.

UPDATE

The reg-rectifier came in from Amazon right quick and I just installed it.  Having just brimmed the tank I didn't want to get the 24 litre monster off again to install it, and installing it with the tank in is tricky, but I managed it.

The kit came with replacement connectors, which is good because the ones on the bike disintegrated when I took them apart.  I was liberal with the dielectric grease and it all went together well.

I fired up the bike and it's now producing a very steady 13.9v and when I rev the engine nothing changes (before it would drop to barely 12.1v suggesting that while the motor was spinning above idle the battery wasn't being charged.  I didn't run the bike hot as I was in the garage with an impending thunderstorm going on outside but the readings I got suggest the strange electrics are resolved.

If you're experiencing regulator rectifier issues usually shown through an overcharging or undercharging (as was my case) battery, look up MOSFET type reg/rectifiers for your model of bike and save yourself a lot of time and money trying to chase down OEM replacements that simply don't exist.

The plan is still on to get the Tiger to 100,000kms by the time it turns 20 years old in 2023.

I wish Blogger weren't so stingy with headers or I'd alternate between the Tiger TMD logo and the new Concours TMD logo as I now have two functional and quite different bikes on the road.

Loud Pipes and Stunting Isn't a Reflection on the Vast Majority of Motorcyclists

Matt Galloway is the long-time CBC host with seventy-three thousand followers on Twitter and hundreds of thousands of listeners on CBC each day coast to coast to coast in Canada.  He tweeted out tonight about the stunting and loud pipes echoing around downtown Toronto on this heat wave Sunday evening.

The police have obviously been given direction to not pressure vehicular traffic during the COVID19 pandemic but this direction has led to a small minority of riders and drivers abusing the situation in a city where no one can leave.

Why anyone would abuse this situation?  It's a good question but one that motorcyclists in particular seem to have trouble answering.  I read a lot of British bike magazines and there is a lot of push back against anti-social riding there too during the pandemic.  When everyone is under the pressure of staying stationary, riding around like an asshole isn't a nice thing to do.

We live in a small town of less than ten thousand and yet I'm frequently unable to carry a conversation when the loud-pipe crew rolls by.  I don't find this safe (loud pipes save lives!) or even considerate or reasonable.  What it is is selfish and usually the result of someone with a massive inferiority complex making a statement about themselves.

What's particularly frustrating about Matt's tweet is that the kickback from the police will make life difficult for everyone on two wheels while also casting our sport in a negative light which will eventually result in even less people participating in our hobby at a time when less and less young people are bothering to get driving/riding licenses.

This isn't going to end well for anyone on two wheels.  Grow up people and try and think about something other than your own gnawing inferiority complex.

3d Scanning a Motorcycle

 Using a Structure Sensor I 3d scanned a 2010 Kawasaki Concours14 and cleaned it up in Meshmixer:

Kawasaki Concours14 3d Scan by timking17 on Sketchfab

The Structure Sensor is an old generation 1 device and isn't as high resolution as I'd like, but it gives you a general sense of shape and proportions.  Meshmixer is free from Autodesk and does a good job of fixing up voids and missing bits in the scan.

This is the model in case you'd like to mess around with it.

Structure.io came out with a higher resolution second generation model that they offer a discount on if you send in your old one.  It might be time to trade up.  My dream is eventually to get a 3d scanner that is accurate enough to scan and reproduce old motorcycle fairings that are out of production in order to produce millimetre accurate OEM replicas to keep old bikes on the road with new plastics via 3d printing accurate reproductions.

The next step would be to scan a customer's fairings and offer customized options based on 3d modelling.  It would be relatively easy to reproduce high quality copies of fairings with some interesting variations in design.  Alternate cooling, MotoGP style wings and even craziness like a motorcycle fairing redesigned with dragon scales of made out of feathers are well within the realm of 3d modelling/3dprinting.

The customized fairing/3d printing direction hasn't been explored yet.  Accurate 3d modelling would also allow a micro-manufacturing concern to reproduce the old plastic bits that are wearing out on bikes from holders and brackets to dash pieces.  Because they're 3d modelled, this would eventually build a library of out-of-production parts that could keep a wide variety of bikes on the road.

I've been dreaming about this kind of digital forge/micromanufacturing company since 2015:  http://tkmotorcyclediaries.blogspot.com/2015/11/iihtm-digital-workshop.html

Disney's Big Hero Six garage is part of the inspiration:

Chasing Intermittent Tiger Stalling: Checking Motorcycle Electrical Systems

I'm starting to think the stalling issues I'm experiencing on my Triumph Tiger might be an electrical issue.  The onboard computer isn't giving me any error codes, but when I rev it the lights on dash dim a bit, which shouldn't happen.

Motorcycle electrical systems are, like many aspects of motorcycling, a simplified and often more high maintenance version of what you see in a car where the extra space and size means you can make things modular, more self contained and cheaper to rebuild.

Instead of packing everything into an alternator running off the engine via a belt, motorcycles break things up to minimize drag on their smaller engines (belt driven systems suck a log of energy out of a small motor).  A bike will typically put a generator inside the motor on the engine crank so if the motor is turning over the generator is using magnets to generate electricity from the spinning motion.  This produces alternate current but, like cars, bikes generally use direct 12v current, so they need something to change the AC to DC.

Regulator/Rectifiers not only switch your power generation from alternating to direct current but they also regulate it so your battery is receiving a steady 14.5 volts on charge.  A failing reg/rec can overcharge or undercharge your battery.

The flakiness of my situation (sometimes it works, sometimes it doesn't) suggests that this is a connection issue.  Before I start replacing parts I'm going to chase down all the connections, Dremel them clean and refasten everything properly.  If I'm still getting stalls and weird light dimming I'll test components one by one until I've isolated the flakey bit.

I teach computer technology as my day job and a flakey power supply (which also converts wall AC to in-computer DC) can produce some very unusual and difficult to track problems in a computer.  This feels like that.

There is nothing magic about how electricity works, but many people are really jumpy about it.  I've found that a rigorous, step-by-step analysis will usually uncover even the flakiest of electrical failures.  It will again here too.

The regulator/rectifier (#7) at the top is under the seat next to the battery.  I'm going to remove, clean and reinstall that.  

The big parts on a bike's charging system are astonishingly expensive!  Replacing an alternator with a quality rebuilt parts will cost you about $170CAD.  To do the rotor, stator and regulator/rectifier on the Tiger would cost me the better part of two grand Canadian!  Some of that might be old-Triumph price gouging, but it's ironic that all the online explanations describe motorcycle charging systems as built down to a price when it's clearly built up to one... on a mountain.  But there are options...
