Accra to Sheringham

 At the end of November I attended the Global Conference for Cyber Resilience in Accra, Ghana. I was on a tight schedule with work expectations so I flew in and out in the same week, but had I the time and resources I would have ridden out. Mapping a route out of the African west coast to Europe is interesting. I got my Ghana visa quickly as part of the conference, but had I ridden out I would have had to do some legwork to get the other countries in order. To ride from Accra to Europe out of Africa would have also needed visas for Ivory Coast, Mali, Mauritania, Western Sahara and Morocco.

A problem with the Mercator map projection that we typically see the world map on is that it shows areas around the equator at scale but then distorts regions as they approach the poles, which is why many people think that Canada is about the same size as Africa when in fact three Canada's would fit comfortably inside it. This was made plain to me as we passed over Dakar in Senegal and then flew on for nearly another three hours to get to Accra (it's about the same distance as Toronto to Saskatoon).

Mercator projections were designed to provide true course headings for ships, and they do it well, but they were never designed to show the entire world. This is a Robinson Projection which shows the scale of things much more precisely.

Keeping those African sizes in mind and at an optimistic 400kms per day which includes five border crossings known to eat entire days by themselves, the African portion of this trip is just shy of six thousand kilometres, much of it across the Sahara.

5836kms across some interesting terrain...

I thought I was the first in my family to get out Ghana way, but my Grandad was dropped off there by the Royal Navy in 1940 and then proceeded to support his Hurricane squadron as they drove and flew across the Sahara to get into the war in Libya. They landed at Takoradi, so day one would be a sunrise departure into the equatorial heat (that needs to be felt to be believed) and a six hour ride up the coast to stand on the dock he landed on 83 years ago.

Of course that already puts me behind the 400kms/day average I was aiming at, but after experiencing 'Ghana Time' first hand, I suspect that trying to keep to a strict schedule is a sure source of madness in this neck of the woods.

It's fifteen and a half days at 400kms per to get to the crossing at Gibraltar and I wrapped up the conference on November 30th. If I left December 1st, I could apply twenty days to the Africa portion of the trip and give myself some time for surprises. That's still a tight schedule though when you consider the borders and terrain I'd be crossing.

If I could be on a ferry on the 20th, I'd be in Spain on the 21st and up in Evora in Portugal at that farm house we stayed at last year in time to meet up with the fam for the solstice. We could put our feet up over the holidays, but I'd eventually push on to Sheringham where I'd have a cottage rented for the rest of the winter and spring. A winter two wheeled insertion into England might require some patience as I'd have to wait for a weather window, though hanging out in Portugal for several weeks during the darkest days wouldn't be a hardship.


What to do it on? Yamaha has a dealer in Accra, and riding across the Ténéré on a Ténéré has a certain appeal. If I rode a Tiger all I'd be thinking about is the Monty Python sketch the whole time. The Ténéré 700 has an explorer edition for 2024 which has a bigger tank and comes with luggage and such. It's not the ideal machine for long overland treks, but it could certainly handle any surprises well enough.

If I were to give into my Tiger fixation, the new 900 Rally Pro model does the trick and would handle the days of making distance better.


Of course, given a choice I'd rather get my unsupported old Tiger sorted out and then take it!


I've said it before and I'll say it again, if I had money I'd be dangerous.

A Colourful SMART Adventures Late in the Season


I've been going to SMART Adventures since 2018. As a way to get myself doing things on a motorcycle that I don't get to do on the road, it's a great opportunity to expand your riding skills. Getting experience on a variety of different bikes is never a bad thing either.

I've had some great days at SMART. A particular highlight was during the deepest, darkest summer of 2020 when I did a full day that started on a trials bike, moved to a brand new GS1250 and ended on a dirt bike. It was a great day of bike learning across three very distinct machines.

Last summer we managed to squeeze in a half day and it was the first time I'd done the expert riding group, which I second guessed myself on being in. Unfortunately the father who dragged his son into it wasn't so introspective. I spent a good amount of money hoping for expert riding opportunities but the afternoon consisted of watching this kid fall off a bike too big for him that his dad kept demanding he ride, and then watching him drop the second bike we had to go back to get for him into a two foot deep puddle. We ended up spending most of the afternoon picking this kid up or riding back to the base after he broke a bike. I needed this trip to SMART to be a win after that last disappointment.

We tried to arrange a trip up in August but things got complicated (dog died, kid going to college, in-laws being difficult) and it never came into focus. I thought this would be our first year not going up to Horseshoe Valley, but Max's reading week was at the end of October and the week before the weather looked like it might hold up, so I signed us up for an afternoon, and this time SMART nailed it, though in fairness it's not their fault if a toxic dad wants to design a miserable afternoon.

Going this late in the season and during the school year means you're less likely to trip over father/son drama. Max got Dave who was the instructor who taught him both ATVs and dirtbikes previously, and I got Tyler who I hadn't had before but is an incredibly talented off road rider who also has a knack for finding where I was at in terms of skill and then keeping us at that edge throughout the afternoon - I learned tons.

Having a look around before the ride out, it's not easy keeping the jealousy in check when it comes to SMART Adventures owner Clinton's bike collection.

Why are y'all wearing rain jackets? 'Cause it was raining... a lot! That's inches deep mud.

We started with some warm ups in the bowl at the base. I've been on a 250 CRF Honda before but this time they had a Kawasaki KLX 300 with bar risers which fit me even better. Tyler had me doing riding with one hand while standing up (in mud), which isn't as easy as it sounds, then rear wheel lock up braking, then both wheels coming as close to locking up the front as we could manage (in the mud). We also did logs and tires, but once Tyler had an eye in on where I was with clutch control and balance we took off into the woods, which were spectacular!


Riding in a thick ground layer of leaves is tricky. You can't see rocks or mud underneath, but it teaches you to ride looser and float over the surprises without over correcting for them. We did a lot of kilometers through the rain and brilliant colours and the riding was never dull.

I'm always surprised at how physical proper off-roading is. With mid-teens temperatures and the rain gear on I was dripping wet with sweat. I worked hard at using my legs to grip the bike so my arms weren't putting pressurized inputs through the handlebars. It's a combination of balance and lower body strength that demands a lot of energy. One suggestion was to turn my feet fractionally into a corner to weight the pegs in the direction I want to go (a Clinton Smout move) and it works!

We got back for a break but before I parked the Kwak we did K turns. The idea is if you get stuck going up too steep a hill you let the bike stall in gear (or kill the motor in gear) and then roll it backwards leaning into the hill and letting out the clutch bit by bit as you turn the back end until you're parallel with the hill (still leaning up it). The tricky bit is once you're near parallel having backed up on the clutch, you start turning the handlebar lock to lock and the bike's nose will fall under the twisting to face downhill. You then stand it up and roll on down. The final move was to bump start the bike. You do this by leaving it in third gear and dropping the clutch at the bottom of the hill as you sit down on the seat. It sounds like a lot of gymnastics but I got it to work on the second try. Tyler said it can really save your bacon if you get stuck on a big adventure bike on too steep a hill.

Just when I thought it couldn't get better, Tyler went and got a couple of the new Surron electric dirt bikes out of the lockup. He gave me the bigger Storm model and then told me (jokingly) not to get it wet. We left both bikes in economy mode because of all the wet leaves over mud. Tyler described 'S' Mode as 'scary', and don't press turbo! 

383 ft/lbs of torque in mud and wet leaves? What could go wrong?!?

I hadn't dropped the big Kawasaki all afternoon despite the crazy conditions. I should have four times but saved it each time. Being able to practice saves is one of the best parts of SMART. I genuinely got to do things on a bike I've never done before, which is the whole point. Sounds ominous, right?

We got out into the woods again and both Tyler and I were down in the first five minutes, but not because the Surron was a torque monster (it's actually easy to get the hang off). It's the lack of clutch after riding one all day that caught me out. I was sliding down the muddy side of a trail covered in leaves and went to pull in the clutch to drop a gear, except the clutch is the rear brake and the Surron doesn't have gears. The bike was out from under me in an instant. Here's a pic from right after - check out that mud!


I finally got myself back on the bike after I slipped in the mud again throwing a leg over it and we went down a second time. The bike took a minute to 're-arm' because I'd popped one of the brake sensors out, but Tyler figured it out and we were off again.

We made tracks after we both learned not to use the rear brake like a clutch.

That's Tyler - ace instructor!

Interesting choice of name, great bike!
No one went down again and by the end of a forty minute blast through the woods and into the trails beyond the SMART owned land, I was getting a feel for the Surron (not Sauron from LotR). Being able to focus on riding without worrying about gears and clutches was one part of it. By the end I was getting crafty with the hand operated brakes. The other piece is the silence. When you goose it the bike roosters dirt like a mad thing, and it's properly quick. The only noise it makes is once you're up to speed and it's a ghostly whine, which suited the October hallowe'en woods. I could hear rain hitting leaves as we whispered through the trees.

Where am I at with an electric dirt bike? If I owned a Surron I'd play with the settings so the energy recovery/gearing pulled a bit more and provided more of what feels like engine braking. That would have prevented the spill on the hill. So much of dirt biking is clutch though. You manipulate the clutch continuously to offer smoother power delivery, especially in tricky conditions. A dirt bike without a clutch and gearing is missing a key control, not to go faster, but to manage the power better. The throttle on the Surron felt a bit wooden after riding the big Kwak all afternoon, but that may well have been because I couldn't feather the Surron's power delivery with a clutch.

The upside is the silence when riding, though it isn't really silent with that ghost whine. It did make me miss the thud of the thumper, and the simplicity of the controls (no clutch, no gears) lets you concentrate on other things, but at the cost of simplifying the riding which I have mixed feelings about.  Aesthetically, a bike having a heartbeat is pleasing, though I could get used to that ghostly howl.

The older much used Kawasaki went through all sorts of gymnastics during the afternoon without missing a beat, while the Surron needed TLC after one drop, which doesn't bode well for its resilience. I'd describe my first time on an electric dirt bike as interesting, but they're not ready for prime time yet. If I were to buy a dirt bike tomorrow it would be a fuel injected ICE model that is decades into its evolution rather than an ebike that's at the beginning.

SMART was running a regional trials event that weekend and I asked Tyler about electric trials bikes, but he said most riders are still using ICE models - once again because the clutch offers much more nuanced control. I suspect electric bikes will end up adopting something like a clutch to allow for that finer control, though they don't need gears so perhaps the clutch is simply another electronic intervention. It's just a matter of time for this to all get worked out, but they're not quite there yet.

As we pulled in to SMART a red fox fan across the parking lot, and I saw wild turkeys and what might have been a coyote in the woods. We clambered out of our muddy gear past 4pm and got changed before heading up the road to Vetta Nordic Spa where we put our aching muscles into various hot waters as we watched the moon rise through the skeletal trees. Yes, the rain stopped and clouds blew over pretty much the minute we stopped riding, but the weather is part of what made it such a good afternoon of riding! As a way to wrap up the riding season (it was snowing the following weekend), there are few better.


You should go!

Finding Your Way Around OEM's Giving Up on Parts Support: Triumph 955i Fuel Injection Seals

With Triumph giving up on my Tiger before I'm prepared to, I'm going to document the research and give details on what works when you're trying to keep a Triumph 955i's fuel system working by replacing old o-rings.

This has involved a crash course in o-rings and engine operating temperatures. As I work out a fix here I'll post details on o-ring sizing, what type works and include data on measuring the intake manifold at temperature.

It's been all Concours for the past few weeks while the Tiger is laid up. I'm hoping to get the fuel system sorted before the snows fly and I have to wait for next year.


Here are the measurements for the upper and lower fuel injector seals. The classy move by Triumph would be to open source publish the technical details for all the parts they no longer support so that the rest of us can get on with keeping the history of the marquee alive. With that in mind, here are the deets for the upper and lower fuel injector o-rings:

The thick ones go on top where the fuel injector meets the rail. My best guess is 3mm thick by 1.5cm outer circumference.


The skinny ones go on the bottom where the fuel injector slides into the intake manifold.

My best guess there is 2mm wide by 1.4mm outer circumference. 






Unfortunately, buying off the shelf boxes of o-rings isn't likely to get you anything that fits. The two below from Amazon didn't. This thing looks handy: https://www.allorings.com/O-Ring-AS568-Standard-Size-Chart.

The Tiger is a metric bike, so I'll work in mm (if Triumph went imperial on o-ring, what the actual f***). The thicker o-ring is 1.5cm or 15mm outside diameter (OD) and (I think) about 3.5mm cross section (CS). Looking at that chart, the #203 is a 14.58mm outer diameter with a 3.53mm cross section. That makes it mighty close. What would be nicer would be if Triumph just came out and gave us the precise sizes for these parts it has discontinued. Triumph?

The thinner one is also a 1.5 (ish) mm outer diameter (15mm-ish), but the cross section is thinner - perhaps two and a bit mm, and they have a 2.62mm cross section standard o-ring size. You'd have to hope Triumph didn't make bespoke o-rings for their fuel injectors, right? For the skinny o-ring I think I'd take a swing at the 2.62mm cross section / 14.43mm (1.443cm) size.

The All O-Rings site also has a good description of the materials you want to get your o-rings in. Nitrile and Viton are what I went with in the pointless Amazon order, but those are the materials you want in a fuel heavy application like this.

That's the configurator (right) - pretty straightforward, but it sounds like they manufacture each order, which probably won't make this a viable solution for someone just trying to keep their old Triumph on the road.

If only there was some kind of network of retailers who supported Triumph motorcycles who could order this parts to help their customers keep their older Triumphs rolling... some kind of 'dealer' network who understand how parts work and how to order this sort of thing in large enough quantities to make a profit while offering customers what they need.

I'd prefer to use All O-Rings for the parts, but they might be a B2B type of thing, and I'm not a B.

Amazon's kits:


Turns out Amazon's shot-in-the-dark kits didn't work either. There's more to this o-ring sizing caper to come. I wish I could just 3d print the nitrile o-rings I was looking for (doesn't look like it's additive manufacturing friendly).

Discontinued Tigers and Triumph Supporting its Riders

If you follow the blog you'll know I'm on a mission to get my 2003 Triumph Tiger 955i to roll over into six figures on the odometer. I picked up the bike with under forty-K on it and have done the majority of the now high miles on it. Over that time I've had an ongoing battle with the early fuel injection on the bike, but other than that it has been my preferred ride even as a series of other bikes passed through the garage.

Once again the fueling has gone off on the bike just as I was hoping to push it over the 100k mark in its 20th year on the road. If I lived somewhere where the weather wasn't trying to kill me for four months of each year this would be an easier goal, but trying to do it in Canada where the bike has to sit through minus forty winters and then navigate the frost heaved results in our too-short riding season? It's technical a flex I'm up for, but it's a shame that Triumph isn't.

I tried the usual solution of rebalancing the fuel injectors, but the bike is still stalling out and running rough. I checked the valves less than 15k ago so that isn't likely it. If it isn't throttle body balancing, which the bike is prone to needing, perhaps it's time to, at over 90k, to finally replace the o-rings and gaskets in the fuel injection system, but Triumph tells me that the majority of these parts are discontinued.

One of the reasons I enjoy the old Tiger is that it still catches eyes and prompts conversation when I'm out and about. Another reason I like it is that it can pretty much do anything (I've trail ridden on it and done multi-thousand mile two-up road trips too). It fits me better than anything I've ridden, is fun to chuck around in corners and has handled axle deep mud when I needed it to. The engine is full of character and pulls well even two up and, considering the miles it has done, the amount of TLC needed isn't unreasonable. I'd love to keep this bike going indefinitely, it's a shame that Triumph don't feel the same way.

I had a chat with the dealer (who isn't particularly local, it's a 170 mile round trip to go there physically - I usually get parts delivered), and they said that this is a problem with Triumph - they don't support their older machines. He then went on to say I couldn't use generic o-rings because the Triumph parts are strangely size specific. I'm going to try anyway because I really want to be able to jump on my old Tiger and ride.

Suzuki runs a successful vintage parts program so I'm not sure why Triumph wouldn't want to do the same to keep their bikes on the road, especially when they lean on brand heritage marketing so much.

Here's Nick Bloor's take on it:

Never standing still, always pushing to get the best from ourselves, for our riders. Building iconic motorcycles that celebrate our past while embracing the future through bold design, original styling, purposeful engineering and a genuine passion for the ride.
Always focused on delivering complete riding experience, creating bikes with the perfect balance of power, handling and style that totally involve the rider and bring out the best in them. 
This is our passion and our obsession. 
We are chasing the same thing as our riders THE PERFECT RIDE.
Nick Bloor
CEO Triumph Motorcycles

All good stuff, but maybe focus a bit more on celebrating Triumph's past, Nick? That includes the bikes your reborn Triumph have been making since the nineties. For some of us you created that perfect ride a while back.

When you market on brand history and provenance, shouldn't you support brand history and provenance? I'm coming at this hard because I want to believe... and keep my (not so) old Triumph rolling.

Fall Moto Photos

 Alas, the Tiger's fuel system is acting up (again), so it's all Concours14 this fall, but the big bike is doing the job. It handles two up without breaking a sweat and when I want to ride it like a sports bike, it never misses a beat. It's heavy, but once it's in motion it seems to loose one hundred pounds. It's no Fireblade, but it's surprisingly willing in the (few) twisties we have around here.

This time of year the fall colours mean you can enjoy a ride even on our tediously straight roads...
