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...

Dream Motorcycle Trips: Madness in the Desert


If you've read this blog you know I've written a historical fiction of my granddad's time in the RAF during World War 2. The two books I've done already are about his time behind Nazi lines in France in 1940, but after he escaped he got sent to Africa and spent the the next chapter of his time overseas crossing the Sahara (in 1940s vehicles!) and fighting in Egypt and Libya. I'm keen to eventually trace his steps but when am I ever going to be on the east coast of Africa?

The Allies didn't have control of the Mediterranean in late 1940 (remember Guns of Navarone?), so the Royal Navy took Bill and his RAF squadron down the east coast of Africa to Takoradi in Ghana. There they unloaded their Hurricanes and ground support vehicles and then they (incredibly), saddled up in their 1940s vehicles and leapfrogged with their planes ***across the Sahara***!!! It's a 5000+ kilometre odyssey that leaves me absolutely awe struck:

Sure, Tim, you're saying, but when are you ever going to get to Ghana? Well... I applied to the Global Forum for Cybersecurity Expertise's cyber-research proposals in the summer and my paper on quantum disruption in cyber got accepted... which means I'm going to Accra, Ghana to present it at the end of November at the Global Conference on Cyber Capacity Building. That puts me about 200 kilometres away from Takoradi where I'd have a chance to stand where Bill stood in late 1940.

I'm feeling pretty scrappy. The dream ride would be to get a collection of 1940s RAF bikes, cars and lorries and repeat that astonishing trek across the desert to the southern coast of the Mediterranean. That's some pretty gnarly country, so doing it as part of a documentary with a film crew that looks at what life was like in the desert in World War 2 would be the dream part of this ride.

Some of my cousins ride and some of their kids are old enough to do it too. There are several times in Bill's military career when he shouldn't have made it out, but he had a knack for it. An opportunity for his descendents (who wouldn't be here if he didn't have that knack) to repeat this Sahara crossing while talking about the history and passing through the heart of the desert on 1940s technology would be... epic.

Yep, that's what epic looks like.

Austin Vince did Mondo Sahara, which was ambitious. This is... more.

Dream Motorcycle Trips: Riding with Austin

I've been watching the inestimable Austin Vince lead his latest VINCE trail riding adventure in the Spanish mountains on Facebook. Austin's Mondo self funded world trips have gotten me through many a long Canadian winter. The chance to ride with the man himself through some of the most beautiful and remote parts of Spain would be epic.

We drove through Northern Spain last winter but it was in a rental Kia. This is Spain next level!

Concours Tip Over

 No pride here at TMD. The other weekend I went out for a ride with my lovely wife and we stopped for a snack. The parking lot wasn't even but the bike was full of fuel and had the top box on and it was a very windy day. I had to lean on it to get it to stand up and thought it would be ok - you might see where this is going.

I was once told that bikes fall over, it happens to everyone, but I've never had it happen before. I'll be more cautious next time. My best guess is the road behind the restaurant channeled the wind making for even stronger gusts and it toppled the bike. We were around the corner on the patio when I heard the worst kind of smashing sound and immediately got up to come around to see Big Blue on its side. I remembered the lift with your legs holding the handlebar in and the back of the seat, and got the big thing upright again.

It started right up and I rode it around the corner to another spot on more even ground out of the wind tunnel. Much swearing ensued but it was really my own fault. I checked it twice to make sure it was stable, but that second check should have told me I didn't like how it was sitting and I needed to find a better spot. Lesson learned.

The wing mirrors on GTR1400 / Concours 14s are (big) plastic pieces over an aluminum frame. They're one of my least favourite stylistic choices on the bike. They work well but they are enormous and make what is already a big bike look even bigger, so my first reflex was to find a lower profile alternative. The bike looks much more svelte when it's mirrorless.

The only aftermarket option I could find is pretty much the same thing - industrially big. I might be tempted to customize something, like perhaps an electronic rear view option, but something stopped me. I've worked hard to get the C14 to fit, but it never has. Bar risers, modified foot pegs and a pang Corbin saddle and it still feels like it was made for someone else. Love the engine and it handles well enough with the rear tire mod (slightly larger profile balances the bike forward a bit more) and getting the suspension set for my size helped too, but it still feels like someone else's bike, so I started looking at other options.

I reached out to the metal shop teacher at my school but he can't weld aluminum. He suggested Fergus Welding & Machine Shop just up the river from us. It was described as 'turn of the century - 18th Century'. I gave them a telephone call (because they have no digital presence at all) and went over to show them my broken mirror frame.

Our shop teacher wasn't kidding. This place is in an old stone building and it was indeed old-school with paper filing upstairs and blacksmith come metal shop downstairs. The broken bit was in fact aluminum and their Yoda-like welder said that if it was 'white metal' he wouldn't be able to do anything with it and that he'd only find that out when he 'hit it' for the first time. I left my phone number on the box and off I went.

I got the bike undressed and cleaned everything up. I'm amazed at how strong the fairings are on this thing. Even with seven hundred odd pounds coming down on it the thing held up with only scratches.



Fergus Welding & Machine Shop called back end of the next day and Dave said he was able to sort it out. It cost me $25 and I tipped them with a six pack. The part was impossible to source used and a new metal piece was asking $260US, so I came out ahead there.

The job was really well done. Dave tacked the part back together following the break and then filled it like the magician he was described as. When I put the assembly back together it fit like a glove - all the holes lined up perfectly and when I took it out for a spin tonight everything is tight and works as it should. It gives you an indication of how over-engineered this bike is that it can tip over, break the metal mirror frame but not smash the mirror itself. There's a lot to like about a C14, but me fitting on it comfortably isn't one of those things.

Undressing the whole bike gave me a chance to clean it up properly. The owner before me parked it in a shed for several years and spiders made it their home. Many webby nests were found throughout, but they're all gone now. It also gave me a chance to lubricate the throttle cables and clean all the electrical connections of which there are many. This bike continues to amaze with how complicated it is, but it's build like a nuclear submarine.


Next steps? Sort out the fairings. If it were a more popular bike I could get some Chinese knock-offs and get them painted for a grand, but I'm not that lucky. I looked up Color Rite who I got the Neptune Blue touch up paint from when I first got the bike. The previous owner had it tip over on him (on the other side) and the touch up made it all but disappear.

Color Rite does good stuff, but it ain't cheap and their shipping (at nearly $100CAN!) is astonishing. If I'm $200 in to touch up, perhaps I can remove the panels, flat them myself and then find a local paint shop to do them up for me. I'll have to see what that costs.

A Perfect August Ride

I grew up next to the sea as a kid and miss it everyday. Sometimes I've just got to see some water. The nearest/nicest way to do that which actually hits the odd corner (I get what I can take in the corner desert that is SW Ontario) is over to the Niagara Escarpment and up it to Georgian Bay. Saturday was a 24°C perfect August day, so off I went.














Some quiet time on the trails at the end of Beaver Valley in the woods and then it was an hour blast back through the tedium to the maddening crowds.
