Triumph Tiger 955i Valve Clearance Check

I just measured the valve clearances on the Tiger.  They're supposed to be checked every 20,000kms, I've put 27k on it since I've had it and who knows when they were done previously, so this was well past due.

Getting to the valves isn't that problematic since I've gotten gas tank removals down to under 10 minutes while I try and trace down this frustrating inability to idle.  Here are the numbers:

Cylinder             Intake                     Exhaust
      1         .13mm & .10mm       .20mm & .23mm
      2         .13mm & .10mm       .20mm & .20mm
      3         .13mm & .10mm       .20mm & .23mm

Intakes are supposed to be 0.10-0.15mm, so they're all within spec.  Exhausts are supposed to be gapped at  0.15 to 0.20mm, so a couple are on the cusp, though they're a tight 0.23mm (you have to push the spacer in there like you mean it - the .2mm is still snug, just not as).

Turning the engine with the rear wheel in top gear was pretty easy - don't grab the spokes, use the tire, you get more torque and it turns pretty easily.  As you turn the back wheel you get the cams pointing up, which is when you check clearances by sliding a feeler gauge under the cam and above the shim.

This Spurtar 32 blade feeler gauge from Amazon is a nicely made thing that offered me a full range of tapered ends that covered what I needed for checking valve clearances on this 955i Triumph Tiger. 

With the Tiger's timing pretty much to spec valve clearance wise, it suggests that my intermittent stalling problem isn't related to valve clearances.  Working on older bikes (and watching Car S.O.S.) has me well aware of what fails on older vehicles:  RUBBER!  Perished rubbers are Tim's go-to in Car S.O.S. when it comes to restoring an old vehicle - this Tim is thinking that's the issue with this 17 year old Tiger too.

I spent today putting things back together and double checking everything.  The vacuum system that feeds the idle control wasn't plugged in 1-2-3 (I had it 1-3-2).  That's something stupid enough that it might be the culprit.  At this point I don't care what it is, I just want the bike to idle to the point where I can depend on it to not stall on me and leave me hanging.

If I get it all back together and find that I'm still stuck with an intermittent stall I'm going to start systemically replacing all the rubbers in it.  Doing a deep cleaning on the fuel injectors is an idea too.  I ran into an old guy at Canadian Tire who swore by Sea Foam for cleaning fuel systems, so I got a can.  I've got some in the Tiger tank for the rebuild which will hopefully be done by tomorrow.  In a perfect world the Tiger will be back to normal and I can go after the valves in the winter if I'm so inclined.  If it's still stalling out on me, It'll be a perished rubber hunt next.

I'm already on it, replacing things as I find them...

It seemed like an extraneous expense when I got this set from our local NAPA auto parts shop, but having o-ring replacements at hand saves a lot of waiting.

A very shiny valve cover going back together again.  10Nm is all you tighten the valve cover down to.

Replacing the o-rings at the fuel inputs (I replaced the original terrible plastic ones with these aeronautically sound stainless steel ones shortly after getting the Tiger). 

I was hoping to get it all together, but I'm fabricating rubber grommets and trying to look into details as I go, so this is as far as I got in the 35°C heat.

Whimsical Tigers

On our recent cross-Ontario ride we were stopped a number of times by people who were curious about the Tiger.  This is an eye catching, obviously modern looking bike with a Triumph logo, it prompted questions.  If they see a new 'classic' Triumph, most of the general public think it's actually a classic.  They wouldn't recognize the difference between fuel injection and carburetors even if it's advertised on the bike, they just see an old machine.

Colourful Triumphs of yore.
The Naughties were neon!

The confusion of a new-looking Triumph (even though it's 13 years old), and what they thought a Triumph should be isn't too surprising, and I'm happy to fill them in on the triumphant return of the brand (it's a good story), but it makes me question the modern bike colours and styles.

When we went to get the Tiger, 11 year old Max's eyes bulged out of his head and I knew we had a winner.  Who makes a Lucifer orange tiger with stripes?  Triumph in 2003, that's who.  When they weren't churning out violently orange Tigers, they were putting out a wild assortment of colours.  Of course, this was before Ewan & Charlie jumped on their austere Bayerische Motoren Werkes R1200s and reset the aesthetic paradigm for adventure motorcycles.

Why so serious?
That muted blue is as close as you get
to colour on a new Tiger.  Other choices
include military green or grey.  A purposeful
look is what sells  adventure bikes  nowadays...
and don't forget to dress like a starship trooper!

Nowadays everything has to appear relentlessly purposeful and ridden by people who look like they've just landed on an alien planet.  Whimsy and fun are replaced by bikes that look like they come from Army surplus, and riders who just got decommissioned from the special forces.  No wonder people were eager to walk up and start a conversation with the guy and his son on their brilliantly orange Tiger that looks like it just popped out of Winnie the Pooh.  The public wants to be curious about motorcycles, but a lot of motorcyclists seem determined to make themselves as unapproachable as possible, and manufacturers have to cater to that attitude in order to sell.

Besides paint options there is also the issue of styling.  I find the compound curves and organic look of our 955i Tiger very engaging.  Whomever was designing Triumphs in the early Naughties did it pretty much exactly the same way I would have.  Since then Triumph, along with most other brands, have been chasing a more chiselled, hard edged look.  Lamborghini did a stealth fighter aesthetic after the Diablo with crisp, folded edges and it seems to have spread.  Between the muted colours, sharp edged styling and attitude driven rider styles, it's little wonder that our whimsical Tiger had people approaching us.

I realize manufacturers have got to build to the tastes of the day, but I'm hoping there are a group of motorcyclists out there who aren't so serious and miss those fantastic styles and colours.  If there are, there is hope that my whimsical Tiger won't be so exceptional in the future.

Even when they're blue, they're
mostly  black.

Black motorcycles are dead sexy. No, really. Researchers at the University of Kentucky (March, 2011) found that in 36% of crashes involving a driver’s failure to observe a motorcycle and then turning into its path involved black motorcycles.

Army green, ready to attack
those adventures!

Looks like whimsical colours can keep you alive!  It might be time to bring back peppermint green and neon puce!

As the years go by, the colours get more and more muted.

I like my Tigers Tigger-like...

Triumph has a great sense of humour, just not with adventure bikes (those are very serious).

West Coast Siren Call

I came up with the idea of setting up motorcycles down south in rental storage units to access over the winter a while back.  This is just the sort of thing I'd do if I had that kind of disposable money laying around.

To set up San Francisco bike storage I'd need to get an Ontario bike down there and parked up in the storage facility.  The idea is to have a ready to go bike that I can fly to with minimal luggage.  I'd eventually be able to fly in to San Francisco with only a carry on bag, take a cab to the storage unit and be on two wheels in one of the best motorcycling locations in the world within a few hours of flying out of the snowbelt.  For the setup I'd take known, works-for-me gear for the ride and then hang it up in the storage unit along with the bike.  Flights back at the moment are one stop, seven hours and about $700 Canadian.

The weather is already closing in here.  We've had dustings of snow multiple times.  This would be one of my last chances to make the ride out west before the white wall of winter descends on us.  In trying to make good time to SanFran, I'd also aim to get a motorcycling bucket list item done:  an Iron Butt thousand miles in twenty-four hours:

Day 1:  Elora to Hampton Inn Portage IL.  Just under 500 miles over the border and to the edge of Chicago.  Make sure everything is ready for the big push on Day 2 (the Iron Butt 1000 miles in 24 hours).  Make sure everything is good to go on the bike, get in early, eat and rest up for an early departure.

Day 2:  Portage IL to Denver, CO.  Be on the road by 5am for the big push west.  Cross Chicago before rush hour picks up and then thump across the plains.  1027 miles in 24 hours.  Get in to Denver overnight and then 2 days at the Embassy Suites by Hilton Denver Stapleton.

Day 3:  Rest day in Denver.

Day 4:  Denver to Grand Junction.  Into the Rockies, 333 miles to the Hampton Inn Grand Junction.  A lower mileage day means this should be as much about enjoying the mountains as it is about making time.

Day 5:  Grand Junction to Ely.  429 mountain miles to Ely and the Ramada by Wyndam Ely passing through 3 national parks, so it should be a pretty ride.

Day 6:  Ely NV to San Francisco.  554 mile day to wrap up the trip.  Get into San Francisco late, park up the bike and put everything into hibernation mode.  Load up a carry-on bag with the essentials and take a cab to the airport.  Retrace the four thousand plus miles back in five hours.

I should be able to take the bike out, park it up and be back home within a week, then I'll have a bike on-call on the West Coast.

For this trip I need something that can cover big miles effectively but is still a useful tool on twisty roads.  The big Triumph Tiger 1200XRx is a long distance capable bike that fits a big guy like me.  It's also easy to maintain (shaft drive, fuel injection) and comes with many long distance handy abilities like long suspension to soak up bad roads and luggage for the long trip.

A big Tiger in this format costs just over $24k Canadian.  It's a pretty thing, I saw the new ones in the flesh at the Triumph Tiger ATLAK meet up last summer.  Many magazines describe the bike as very large, but I didn't find it overwhelmingly so.  In fact, I was surprised at how svelte it was for a 1200cc adventure bike.

But there are some things about the big Tiger that I'm not a fan of.  I've never gotten excited about the big aluminum panniers thing on adventure bikes, or any bike for that matter.  I like the colour matched lucifer orange ones on my old Tiger.  I think the aluminum ones look half assed and unfinished, and I get to pay hundreds more for the privilege of having them because others think they're a fashion item.

The other issue is a recent BIKE Magazine review in which their Tiger developed a number of electrical issues.  Whatever is waiting for me on the West Coast would need to work when I opened that storage unit roller door.  The Tiger is also a reasonably sensible choice, but it'd be nice to have something a bit more come-hither waiting for me in San-Fran.

For surprisingly similar money there is something that I'd describe as more of a dream bike:  the Kawasaki H2 supercharged demon bike in sport touring form.  The H2 SX is an efficient, powerful, supercharger-chirping-as-it-breaks-the-sound-barrier thing of beauty.  It weighs about as much as the big Tiger but produces prodigiously more power and looks like a Japanese super model.

On top of that it has beautifully designed and colour matched panniers that practically disappear into the stunning looks of the bike, rather than looking like tacked on, low-rent metal boxes.

Having the SX sitting in a storage unit in San Francisco would be a constant West Coast siren call.  If I wanted to go far, it could handle it, if I wanted to canyon carve in and around San-Fran, it'd do that to.

As much as I love adventure bikes for how well they fit me, I think I'd have the Kawasaki super model waiting for me on the west coast.  It'd be a blast to ride on the trip out there and would fit in with Californian bike culture much better.

Prioritizing Work and Saving My Patience for What Matters

I was talking to Alan Seeley on email who now writes for Classic Bike (UK) Magazine. I told him about the s*** show that was trying to order used parts from eBay to keep the old Tiger in motion. He put me in touch with Chris Jagger and also put my issue into the letters section of the magazine. Chris's advice is that there are weak points on these bikes and as they age they get retired because of the lack of support. If you're going to take on a Hinkley Triumph, even a relatively recent one, don't expect the kind of support you'd get from other manufacturers.

I've sorted out '90s Fireblades and Honda never blinked when I was looking for parts. Suzuki is legendary with how they look after their engineering history, and Kawasaki has also been nothing but solid when I was working on older machines. I actually found it easier to find parts for a 53 year old Meriden Triumph than I have with much newer Hinkley machines. I've said it before and I'll say it again, for a company that markets on their history so heavily, Triumph vanishes when it comes to providing parts support, even for recent machines.

I took Chris's advice and went looking for backup used parts. This time around I found a throttle body that looked like it has spent some time in an archeological dig, and it arrived in a beaten up box but this time the seller padded it well and the plastic bits were intact. I cleaned and dismantled the unit and now have spare throttle bodies, fuel injectors and a complete idle control housing along with all the other odds and ends.

When I put the Tiger back together I tried putting pins in the broken wires on the fuel sender but it didn't work. I got a replacement fuel sender, but this time from a US eBay parts provider. I foolishly thought the shipping would be less but eBay surprised me with a surcharge on delivery that was 3x the shipping costs. Both the throttle body and the fuel sender came in on the same week. The throttle parts were much bigger and heavier and came from the UK with no surprise surcharge and the shipping cost was 30% lower. The moral here? Don't buy used parts on eBay if it's from an American based seller - you'll get caned by US Post surcharges. No so with UK suppliers.

The good news is the new part works well, but not without other teething problems. That age of this bike is really starting to show. The wires had broken in the sender unit but unbeknownst to me they'd also broken on the other side of the connector, so when I first plugged the new unit in I got nothing. After taking the tape off I discovered the broken wire, cut off the connector, crimped on new plugs and it works a treat.

While I was waiting on parts I pulled the valve cover and checked the valves just to make sure they weren't what might be causing the stalling and hesitation.

I'd last done this perhaps ten thousand miles and a couple of years ago - everything was still within spec. It's an afternoon to do it but worth knowing that the valves aren't the issue. That also gave me a chance to go over the seals on the airbox and pipes, clean and check the spark plugs, put a spacer on the throttle return to stop it stalling and wire in a bypass to the battery so it's showing 13 volts when running now (the wiring for the battery is byzantine and loses voltage over time). I also rebalanced the throttle bodies while I was in there.

With the new fuel sender in, I've had the Tiger out multiple times over the past week. It doesn't stall! It starts reasonably easily, Shows 12.8-13.2 volts when running (it used to hover around 12), and the throttle action is close to what it was before things went sideways.

How am I able to apply such patience to the Tiger? I sold the Bonneville!  Got what I paid for it and took a hit on some of the new parts I'd purchased, but with it gone I've got more room both in the garage and in me head to work on the Tiger.

The old Bonnie was interesting to work on during COVID but I'm still young enough to be motivated by riding rather than spending endless days in retirement hunting for expensive parts and installing them. Having two frustrating Triumphs was one too many, and since the Tiger's going to start demanding engineering rather than just mechanics if I want to keep it in motion, it was time to let go of my first attempt at (the eye wateringly expensive world of) vintage restoration. I like my projects to be more recent sidelined bikes - the '97 Fireblade remains a highlight (that I made money on!).

The Bonnie project had stalled out when I realized I was a grand in on new parts and nowhere close to being able to ride the thing. In retrospect I should have picked one of the other running options, but I went for the romantic Triumph option... and regretted it. An alternate reality Tim went for the BSA trials bitza and is deeply involved in vintage trials right now.

Links & Pics

Valve cover off on the Tiger. It's pretty easy to get into - other than having to wiggle the cover out the right side under the frame - which actually caused problems on the reinstall when the gasket didn't sit right and the bike barfed expensive synthetic oil all over the garage floor when I restarted it- but I'm not going to mention that in the blog.

With the Bonnie and bits gone, there is much room (both mentally and physically) to get on with keeping the Tiger in motion. The Kawasaki remains rock solid.

Used on Triumph models up until  four years ago - they don't make these any more.

I'm taking the broken one to bits and measuring all the bits. I currently have two plans: 1) digitally 3d model the part and look into 3d printing options with fuel proof materials. Nylon filament printing seems to be the fuel-proof material of choice. Lots of services out there. 2) is to build my own copper/steampunk version of this plastic bit using copper piping and fittings.

My pins in the connectors attempt with the old fuel sender didn't cut it.

I thought the C14 might have an oil leak, but it turned out to be the oil in the fairing after the spring oil change. After a thorough cleaning it's running like a (oil tight) top.

Here are some details on the voltage fixes for 955i Tigers. Running the wire from the reg/rec to the battery was straightforward:

Thanks to the massive shipping surprise it would have been cheaper for me to buy this new from a dealer (assuming they haven't discontinued it). Don't buy used parts from U.S. based eBay parts providers! It's not their fault, but eBay makes a mess of US/Canada shipping.

Tiger Test Ride(s)

 The Tiger rode like it has never had any fueling problems after I hacked the idle control system last time. Idle control is a common problem on 955i Triumphs and I've spent years trying to get mine back into spec even as finding parts for them gets more difficult. Turns out the solution is to remove it.

Ride #2: 40 minutes locally

Second ride this week and the bike idles rock steady and is as smooth as it has ever been, and the backfiring that had been getting worse is completely gone. Today it started on the button, ran from cold with no issues and took me on a 40 minute ride without a hiccup.

We live in an overcrowded little town now thanks to Southern Ontario swelling in size post COVID, so I took the Tiger through a lot of stop-start traffic to see if I could get it to hiccup, but it wouldn't! Makes me want to move more than ever though.

No problems on the back roads.

Pickup up from stops, no problem. Cornering roll on throttle? Smooth as butter. Idle never wavers and I'd forgotten how much fun to chuck around the Tiger is...

So if you're having never ending headaches with your Triumph 955i idle control system, yank the damned thing! Modulating the idle through varying the vacuum between the intake manifold and the airbox (the servo moves up and down revealing the vacuum passages for the three throttle bodies) serves some purpose (perhaps emissions?), but at this point in the bike's life at over 90k and 22 years in, removing the lot and connecting the intake vacuum lines together offers a viable fix for what may be one of the last of these bikes on the road in Canada. I'd be willing to play Top Trumps with any other 955is on mileage too.

Ride #3: Going Long

The next run was a 275 km run up to Georgian Bay to look at a blue horizon. These days it's also a reason to get out of our increasingly overcrowded and traffic jammy town.

The first 45 minutes are straight lining through farm desert, but the geography starts to get some character once you get into the Niagara Escarpment in the Gray Highlands. I didn't throw the 360 camera on until we got to the less tedious bits.

At just under half a tank the Tiger took me 140 kms and two stops to a fuel stop between Blue Mountain and the big water. It was still showing most of the red on the fuel gauge and took less than 17 litres (it's a 24 litre tank), suggesting that this mod isn't hurting mileage.

After the fill up it was some twisty bits over to Creemore for a bite and then the long haul back through farm desert (with its big, juicy flies) and then lines of traffic to get back to my driveway. Through it all the Tiger was mighty.

Flesherton to Thornbury through Beaver Valley (41kms)

Thornbury Harbour to Creemore Brewery (77 kms)

Thornbury Harbour!

Just past the scenic caves on Blue Mountain.

Creemore for a late lunch.

Steady 100km/hr sections, twisties, as big an altitude change as you can find in Southern Ontario and we never missed a beat. Left at 10am, got home just past 4pm, multiple stops, always started on the button whether cold, hot, or somewhere in between.Temp was mid-teens leaving and mid-twenties returning.

It's been a while since you've heard this on here, but I'm a happy Tiger owner.

1) Bin 2, 3 and 4
2) Remove the top of the servo (1) and leave it plugged in but detached from the airbox.
3) Block off the hole in the bottom of the airbox left by the removed idle control stuff..
4) Plumb the three vacuum lines out of the throttle bodies into each other through a T-junction.

Bob's your uncle! No promises, but it did the trick for me.
