1971 Triumph Bonneville Project: Engine Out

The weather's all over the place at the beginning of March this year.  Last weekend I had both road-ready bikes out for a shakedown, this weekend we're skiing in -20°C windchill; that's the road I was riding on last week.

As GP from Hammy Hamster would say, 'the elephants are against us.'  With the outside trying to kill us again, I'm focusing on doing a complete tear down of the 1971 Triumph Bonneville project.  I was originally going to see if I could get the bike in motion as it is, but a combination of factors including 1971 Triumph build quality and the early 80s muppet who tried and failed to turn the bike into a chopper's spannering skills have me now approaching this as a frame up restoration.

I've been working around the edges which has been good for reconnaissance in determining what state the bike is in, but now that I'm committed to doing the bike from the frame up the first job was to remove the bottom end of the motor and clear the way for a frame restoration:

The bottom end was surprisingly light and easy to lift out of the frame and none of the frame to engine bolts caused any problems.  Some were quite loose, so a frame up resto is making more and more sense as I don't trust anything the chopper muppet did to the bike circa 1983.

It was my first time into the rear drums and, like the fronts, they were age seized but otherwise not in terrible shape, though whenever I get into the dark places on this bike it looks like a scene out of Indiana Jones.

I've left the frame on the bench as I continue to strip it of accessories.  The last time I did some coating work on a project bike it was with Fireball Coatings in Elora but seven years on they seem to have evaporated.  I've been looking for alternate (and hopefully better) options and KC Coatings in Guelph looks promising.  I intend to get in touch with them and see if we can shot blast and powder coat the Bonneville frame, I just have to make sure they can do it on a complicated oil-in-frame design like this one.  Powder coating adds thickness and can cause problems with fasteners and fitting things back together so I need to find out if KC understands that and can can work with this one so that its mechanical pieces will still fit back together.

Following the frame I'll sort out both wheels (bearings, tires and inner tubes) before getting the rolling chassis back together and then rebuilding the motor with my swish new 750cc head.

Motor out and on a pop up workbench by the window.  It's lighter than it looks.

I set up the Black & Decker WorkMate by the back door to the garage to give me somewhere to work on the bottom end of the motor.  With the engine split and out of the frame, I can lift the parts off the bike around easily.  I might put the bench away and make some space while the project is in pieces.

Revco is fantastic at shipping (even during a pandemic) and very transparent and communicative with delivery times.  Everything I've gotten from them has been expertly packed, is new stock (no old/new tires).  They know what they're doing with motorsport tires.

If I had more space I'd have welding kit and an English Wheel set up in the workshop and get into a lot more fabrication.  I'd go digital too.  A industrial sized 3d printer would make me dangerous:  https://tkmotorcyclediaries.blogspot.com/2015/11/iihtm-digital-workshop.html

Café racer

I've been getting a handle on café racer culture recently.  A good place to start is the documentary below available on youtube:

A motorcycle phenomenon that combines DIY backyard mechanics, customization, restoration, links to British post war culture and a focus on pure two wheeling?  I'm in!  When you also factor in the old RAF inspired bike gear café racing only gets better.


What first got me thinking about it was It's Better In The Wind, a beautifully shot and music themed short art piece about friends on their classic café racers.  As a mood piece it captured a lot of the gritty romanticism in motorcycling.



Last summer I was reading Shopclass As Soulcraft, and in it Matt Crawford described motorcycling as 'a beautiful war', which captured the risk and reward beautifully.  That book is mind expanding stuff written by a guy who walked away from academia and the magical thinking of the thought economy to open his own independent bike repair shop.  It's a must read, change your life kind of book that will make you want to get your hands busy again; just the sort of thing that racer building encourages.

I've tried my hand at restoring old cars or just keeping them on the road, but that tended to be a make it work to get to work kind of situation, lots of stress in that.  This is a hands on project that may very well lapse into a piece of rolling sculpture.  Mechanics, electronics and sculpture? I'm in love with the idea!

So, I'm on the lookout for an old bike that needs to come in out of the cold for the winter, one that's looking for a new lease on life.  It can be rusty and rough, the more it needs changing the more I'll want to change.  The end result will only enhance the feeling of oneness I've already felt with the Ninja.

There are many café racer links that will catch you up online:

Winter Is Coming

My first season in the saddle is rapidly coming to an end.  I'm sad.  I've been OD'ing on magazines and media in the past couple of weeks but I'm also doing more concrete things to keep the dream alive over a cold, dark Canadian winter.

This weekend I'm finishing the garage (insulation & ply-board) which should make it more inhabitable for stage 2 of Tim's cunning winter motorbike plans.

With the garage organized (a tire rack for the car's off season tires, new workbench, shelving, etc), there should be a lot more room!  The Ninja will find a nice corner to spend the winter (while I strip the fairings off and refinish the frame).  In all that empty space I feel a strong urge to project bike!

One of my earliest motorbike urges was driving by an old Honda on the side of the road over and over again.  That bike was selling for $450.  If I can find an old bike that needs some TLC I'm going to get it home and give it a place in the garage.  I'll spend the winter stripping carbs and breaking it down to nuts and bolts.  The best way to understand is to lay hands on.  Having a rebuild project would be the perfect way to keep myself immersed in two wheel thinking.

Come spring I might be kick starting an old beasty that hasn't rolled on roads in years.  My recent infatuation with Cafe Racer culture might inform this process a bit.
