'97 CBR900RR LED Indicators and Rubber Parts

The Fireblade project has the main bits (fuel leak leading to an engine drowned in gasoline) fixed with a carb rebuild and a new petcock.  But there are lots of bits and pieces to sort out before I go get it safetied and put on the road.

The weather warms up tomorrow so I'm hoping for a ride, but Saturday was a -20° March 7th kinda day, so into the garage I went to get the little details worked out.

I was initially going to hold off on the LED indicators, but dead bulbs and broken covers on a 23 year old motorcycle meant the LEDs were actually the cheaper, easier and more modern looking fix anyway.  I'd brought a second set when I got the ones for the Tiger, and also got an adjustable indicator relay, so I had all the parts on hand.






The rear indicators look like they were attached by a monkey.  I ended up pulling them all off and removing all the stripped, half installed wood screws that were holding them in.  I then drilled a hole in the rear plastic under-tray and mounted the second set of LEDs I had on hand from the Tiger upgrade.




The wiring was pretty straight forward with green being ground on both indicators (connected to black on the LED) an orange to LED power (yellow) on one side and light blue to LED power (yellow) on the other.  The LEDs also have brake light function where they strobe when you first press the brake.  Both red cables on the LEDs go together into the middle pin on the brake lights.  It works a trick:

Some other odds and ends are also proving troublesome.  Living in rural Canada means everyone's still in love with imperial sized fasteners.  All our local hardware stores have rows of 'em, and maybe 2 metric bolts.  It was tricky figuring out the sizes of missing fasteners anyway, but some internet research into OEM parts supplier parts listings got me this far:

Bolts to hold down the fuel tank:
96300-0604007
Bolt, flange (6x40)


Other metric sized bolts in the same assembly:
BOLT, FLANGE (6X20)

BOLT, FLANGE, 6X32 CBR900RR FIREBLADE 1997 (V) CANADA


A 6x40 metric bold means (as I understand it) a 6mm wide bolt that is 40mm long.  But metric sizing also looks like M6x40. I'm assuming their the same but don't understand why there isn't a consistent format for metric bolt sizing.

Lots of links to other websites.

The bolts into the frame that hold down the fuel tank and the brace for the windshield are 6x40, but I couldn't get an M6 bolt in there.  I ended up cleaning out the thread by tapping it out again and then it went in nicely.

Rubber parts are particularly hard to find on this kind of bike - it's just old enough for existing stock to be gone and just young enough not to have a classic aftermarket parts ecosystem.

The cracked airbox rubber connector to the carbs is nearly impossible to find.  The only
online place I can find them is for a full set of four plus shipping from Europe and ends up at over 70 Euro ($110CAD)... and I only need one of the damned things!

I'm looking into some cunning fabrication options.  Some people have tried plumbing PBC couplings as a kind of secure bandage over the original rubber tube.  Though if I can find one that is the right diameter and well put together I might simply be able to trim it and substitute it.

Others have tried various fixes like heat shrink or inner tubes.  I'll do some more research and figure out next steps...



These guys suggest silicon hose as a temporary measure.  Since what I need is on the airbox side (I was easily able to get carb side rubber replacements), it shouldn't see too much gasoline so the silicon fix might be the quickest way forward.

These guys suggest a sealant.  Again, because it's not on the carb side this might do the trick.  In terms of cost this is the cheapest fix, so I'll probably start here and see how it goes.

I'm wondering if I can't 3d print the correct part.  There are flexible materials we can use to print objects using a 3d printer.  I suspect we're only a few years away from having a 3d printer in our garages that can print these rare parts out of flexible filaments:

February 23rd: First Ride of 2020

The Weather Network suggested that we might get a break in the never ending snow and ice, and on the weekend of all times!

After a couple of days of near zero sun, Sunday hit the target with a 6°C high and lots of blue sky.  The last time on two wheels was November 26, 2019, so that's 89 days of misery.  That should be the longest break as I'm likely to steal some more rides in the coming weeks.

Here are some photos from the ride using the Ricoh Theta V wrapped around the rear-view mirror.  Here's the how-to on doing on-bike 360 photos.  I stopped to look at the bison since they were right by the fence...


















Back home again I washed the salt and sand off and hibernated the Tiger again.  The new LED indicators work a treat.  The old Triumph fired up at the first touch of the button after a nearly three month hiatus.  The new front brakes were a little vague until they bedded in, then they felt as sharp as ever.  The chance to ride has me dreaming about making miles again soon.

Mid-Winter Motorcycle Maintenance: Triumph Tiger Front Brakes



It was a busy long weekend in the winter maintenance garage.  In addition to going over all the electrical connectors on the Tiger, I also did the front brake pads, which weren't making any noise, but after last year's noisy rear brakes forcing a change during the too-short Canadian riding season, I figured some preventative maintenance was in order, and good thing too!  You can see the metal noise strips just becoming visible in the photo.

The brake change was pretty straightforward with the caliper pin cover coming off with a bit of heat and the rest of the pieces coming apart with no problems.  After cleaning up the metal spring pads with a wire brush and thoroughly cleaning the calipers, everything went back together with minimum fuss.  The caliper action was nice and smooth and they willingly got pushed to full open to accept the new pads.  After a couple of pumps of the lever everything was tight and grippy again.  I managed to find the types of caliper I was looking for on Fortnine, and they happened to be orange and look good on the Lucifer Orange Tiger.

The only real pain were the brake master cylinder cover bolts.  The first one came out easily enough, but the second didn't want to come no matter what I did.  Eventually a hammered in Phillip's head screwdriver and some heat cracked the bolt's grip and out it came, but it's pretty mangled.

I was able to find that the bolt is a countersunk M5x16mm bolt.  It's a pretty common thing so I'm hoping I don't have to order it online and can pick one up locally.  It's probably too much to ask to find one that's got a nice coloured, metallic finish.

That covers what I wanted to get done as far as winter maintenance goes with the Tiger.  Other than the brakes and a clean and grease, it was all about the LED indicator upgrade.  Next year it'll be a swing arm removal and chassis grease and it'll have been several seasons since I last did the brake fluid and coolant, so that's on the future list too.  Now it's just the long wait for spring and a chance to get out and ride again.

In the meantime the Honda Fireblade Project is also in pretty good shape.  The carbs are sorted, as is the petcock.  I'm only waiting on a break in the weather to test everything.  In the meantime I've got another set of the LED indicators waiting to go on, but I'm tempted to wait on that as long as the stock ones work.

If you had £70k to spend on a car, which would you choose? Much more than a car!


£70k?  Yikes, that's $121,026 Canadian!  If I can opt out of the dick swinging options above, here's how I'd spend my hundred-and-twenty-K on things with four wheels, and two:


Mazda 2019 MX-5 RF GT
$44,870 CAD
That's a GT model with bells and whistles.  Put me on a twisty mountain road in this and your typical knuckle dragger in one of Top Gear's choices and I bet I'm the first one to the end... and I won't be sending it in for service and repairs every five minutes - and it looks spectacular!


RAM ProMaster Van
$44,625 + $15,375 upfit = $60,000
If you've read this blog before you know I've got a Guy Martin/van obsession that often coincides with a mid-Canadian-winter psychotic episode (I'm getting close now) involving escaping south with a bike in the back for a chance to get on two wheels again.  The Ram's a funky van.  I'd keep back another $15,000 to upfit it into a long distance camper/bike hauler/multi-use vehicle.


That puts me at about $105,000 Canadian with two new, very different vehicles.  What to do with the other sixteen thousand?


Suzuki DR650SE
$6000 (!)
They're on sale at the moment and a rock solid piece of off the tarmac ready kit.  It'll keep up with traffic on the road (unlike the KLX250 didn't) and take me anywhere - including expanding the short Canadian riding season by tackling the odd bit of snow.  I might look into some enduro competition with it too.  It's be a rough and ready option in situations where I'd be worried about a more road ready bike.


I've still got ten grand to play with and I've already had more fun than any of the try-hard Top Gear choices.  Time for something really frivolous that'll be as fast or faster than any of Porsche/Renault/Lamborghini nonsense that kicked this off.


'08 Suzuki Hayabusa
$7000
The first thing I stumble across on Kijiji is a $7000 '08 Suzuki Hayabusa.  Odd that Suzuki is the only Japanese manufacturer I've never owned and I've got two on the list this afternoon.

I've got a thing for orange bikes, and this one looks a peach - older rider, low mileage for the year and well looked after.

I'd hold back the other three grand just to make sure this is faster than anything on Top Gear's list because I like to be Tom... Petty.


If I had £70k to spend on a car?  I'd buy a nice car, a useful van and two awesome and very different motorcycles!  Why be dull?

MotoGP Technology and Motorcycle Dynamics

Neil Spalding's MotoGP Technology is a dense read.  I got it in September and I'm still only two thirds of the way through.  I read a bit, then chase down details so I make sure I've got the concepts understood.  This approach isn't very efficient, but it is thorough, and I've got bugger all else to do motorcycle wise over this long, cold, Canadian winter.

I've been an avid watcher of MotoGP for seven years now, including riding down to the last Indianapolis MotoGP race in 2015, but this book has made me literate in the mechanics of Grand Prix bike racing in a way that I never was before.

I've also spent a fair amount of time coming to terms with motorcycle dynamics and especially how these bizarre machines move around corners.  From watching Keith Code and reading Twist of the Wrist 2, I've tried to understand the inputs I need to make to control a bike effectively.  Spalding speaks with great intensity about how the technical side of MotoGP serves that sense of feel when building a prototype for a specific rider.

After all the team histories that kick off the book, Spalding goes after the various technical tricks that make a GP bike move like a jet plane, at least in the hands of the maestros.  The chapter I just read was on reverse rotating crankshafts, which led to a look at the complex gyroscopic effects happening on these extreme machines.  Spalding suggested looking up Eric Laithwaite and gyroscopic procession, which led me to this:



As Professor Laithwaite describes it, the spinning weight already has a path it wants to follow, he simple lets it follow it.  In doing so, what was suddenly a difficult to lift weight becomes effortless.  There are a lot of gyroscopic forces happening on a motorcycle in motion, especially at MotoGP speeds, and Spalding focuses on this in the later chapters of the book.

Curiously, considering it's 2020 and we have computer technology that can accurately model complex physics, it's apparent in the book that the physics happening on a motorcycle in extreme conditions are more a matter of educated conjecture than known fact.  Our best guesses are still what drives our understanding of the complexities of motorcycle dynamics, which is an incredible thing to realize.  How many people can say their favourite sport isn't fully understood by science?


Neil Spalding's MotoGP Technology is super current (it just got updated in the summer), written by an expert with decades of experience and insider knowledge, and delves deep not only into recent MotoGP technical history, but also into the physics that this technology is up against.  If you're interested in taking your understanding of one of the most extreme sports on earth to the next level, MotoGP Technology will help you get there.


With mysterious physics happening underneath them, what do MotoGP riders do?  They drift 250+ horsepower prototype racing machines... with their elbows AND knees on the deck!  MotoGP Technology will take you a step closer to wrapping your head around this genius, and the technology that enables it.

Moto Anime

Best. Wheelie. Ever! The Robotech Cyclone rocks!
At the end of the 1970s as a nine year old I came across Star Blazers, the English version of Space Battleship Yamato.  This was my first look at Japanese animation, which was quickly followed up by Battle of the Planets and Robotech.  It's safe to say anime was a major influence on my developing sense of aesthetics.  Being Japanese, there were an awful lot of motorbikes in the various stories, probably because many of the people making the animation were riders.


I've written about motorcycles and anime before, in fact you could probably call it a recurring theme.  The history of motorcycles in Japanese animation is a long and storied one.  Motorcycles themselves are deeply embedded in the Japanese psyche, in much the same way they are in Western history.  As a symbol of freedom and power, there is little that comes close.

If you haven't dug into Japanese anime and you're into two wheeling, you're missing out.  Anime offers a distinct angle on motorcycling that is often at odds with how it's presented in film and TV.  It's also quite culturally distinct.  Japan has a rebel biker culture similar to but distinct from Britain's cafe racers or North America's one percenters.  Anime films like Akira make that culture a big part of their story-lines.

Sometimes I forget how many times my formative, young mind saw motorcycles in anime in the 1980s and filed the idea away.  I'd actually forgotten that Princess rode a bike (albeit with rockets, missiles and it transformed into part of a spaceship - but who wouldn't want that?).

My life-long mecha メカ fixation (one I share with Guillermo del Toro) often merges with motorcycles.  The Japanese Shinto religion believes in a pan-theistic world where there are many gods or kami that can inhabit anything, including machines.  Many motorcyclists are prone to this Shinto-ist belief - if you don't believe me ask one what kind of personality their bike has.

Princess from Battle of the Planets rides like she stole it.

Have you tried tickling the carbs?
If you like the romance of riding, you'll find it in anime:



Akira is a seminal anime from the 1990s set in a dystopian future Tokyo where Bosozoku biker gangs have run amok!
Like Kaneda's bike?  It's two wheel drive pushed by a cold superconducting electrically driven power-train on a carbon/ceramic frame.  The whole thing comes in at just over 150 kilos.  You're seeing it folded down in the lower profile high speed mode, but it bends in the middle into a more standard shaped machine when needed.  It's rumoured to be a Honda, but any manufacturer's markings are gone from the stolen bike used by Kaneda in the film. Someone spent a mint making a working model of the thing.


There are a lot of anime that focus on motorcycles, usually with a dash of mecha thrown in for good measure.  Rideback is a near future anime with modern digital animation that focuses on robotic motorcycles, but the main relationship is between an injured ballerina and a modified bike that has all the rider aids turned off (she is the only one who can ride it because of her athleticism).  Once again you get a strong sense of Shinto as the bike itself is presented as a character in the series.  The relationship between it and Rin Ogata allows her to heal after her career ending injury, it's good stuff!

Baribari Densetsu is another moto-specific anime that's worth watching if you love riding. Have a watch below, you'll see what I mean.  This was obviously made by people who ride:


Racing on public, mountain roads by bosozoku on modified bikes was a social issue in 1980s Japan.  This anime follows the story of young men learning how to ride fast before going professional on track.  It parallels the lives of young racers at the time.

If you've never given Japanese animation a go, don't think it's all one thing.  You can get everything from violent, adult only feature length films to school girl soap operas, and you can bet there are bikes in pretty much all of them.


20 best anime with motorcycles:
https://www.ranker.com/list/best-anime-about-motorcycles/ranker-animeKino's Journey is a good one I forgot to mention - there are a pile on there I haven't seen before that are now on the hunt list.



Of course, there's always Sturgill Simpson's Sound & Fury on Netflix where the muscle car driving samurai becomes the moto-samurai with robot support...
