Can-Am is a registered trademark of Bombardier limited, Canada and my pages have no association with that wonderful company.

This site is meant as a place to buy/sell parts, share tech ideas and recently for me to offer you some unusual parts.

Back in my 30s I was big into Can-ams and Maicos even though I was a flat tracker. 49 years later I’m back into Can-am. $225 got me back from a 2002 Craigslist ad showing this 1979 Qualifier. It’s in pieces but is slowly coming back to life as an ice bike. It will look like a 1980 MX but will use the old style tank because vintage flat track tanks aren’t wide enough for C-A’s huge back bone.

Can-am Parts

Can-Am Cover screw set $24.95

can am screw set 1I needed cover screws for my 175 TNT. I checked the cost of Allen head screws at a hardware store and the price was about $32. Screw that. I bought stainless Allen socket head screws in quantity. I offer them to you for about what others on Ebay ask for a set of used Phillips screws-around $25 bucks. Phillips screws are awful. They round to the point of swearing and screwdrivers flying across the shop. These cap screws meet DIN standards and they have a class 6g thread (6mm-1mm pitch) and the minimum tensile strength is 70,000 psi. Stainless Allen socket head screws are such a smart idea. Hex screws tighten and loosen easily without the hassle of damaging slotted screws. Stainless steel won’t rust over the years. For added insurance, dab blue Loctite on the screw threads. Red Loctite is too aggressive to be used on fine threads-it can damage them.

Vintage Can-Am Style Tool Bags

gen 1 can am tool bag 1Can-Am and European off-road bike restorers and vintage racers are looking for period proper tool bags. Harley fork bags won’t cut it. Here is a new replica of Can-Am Gen I bag that will be perfect on Huskys, Pentons, TNTs, Qualifiers and maybe on Buls, Ossas, CZs and Maicos. It measures 9 1/8” (270mm) long x 5 ¾” (150mm) wide x 4” (100mm) tall. It’s American made by a leather worker who has been in the business for years.

The two end flaps were cut from bull hide and are 3/16” (5mm) thick. The other pieces are 1/8” (3mm) thick. Needless to say this bag is a tough cookie. My guy cheated and used wider head rivets because the original narrow rivets pulled through the leather. All other pieces are like the original because the same hardware is still used today.

With the bag I include a 3/16" PVC plastic plate which will inhibit the bag from conforming to the fender as time goes by. Mounting fasteners are also included.

Tech Stuff

Making a pretty Can-am engine

Most of you guys rebuild a can-am to race and don’t give a hoot how the bike looks so long as it howls. The other bunch of you are the beautiful builder types who want a show bike. Then there the fringy minority who want to race with a stunning TNT, Qualifier or MX. I’m on the edge of the fringe with custom show/race builds.

If you get into the weeds enough that you are painting your cases here’s how to reveal the painted Bombardier embossed logos on the case sides.

  1. cutting bandUse a cutting/polishing band like this on your grinding wheel. These parts are on the web-I get mine from McMaster-Carr. The idea is to cut through the scratches and leave a smooth top surface to the logo-with a power tool. If you don’t use this step, you’ll grind up an hour minimum, sanding down through paint, primer then into the metal going after the use-scratches. Use the blue fine band.

  2. Prep the metal for prime and paint. Paint all the case parts because you’ll go fruit loops trying to mask off the raised logo. There some trick new wet media blasting techniques that may reduce the post-blasting clean up to keep the crud from destroying you engine an hour after starting it for the first time.

  3. bombardier part maskedMask around the logos with a couple layers of tape. If you don’t the sanding block will over-shoot and screw up the paint job.

  4. bombardier part paintedWrap a sanding block with 320 wet/dry and water and attack the logos. Sand until they’re clear of paint and primer. If you have nicks and gouges-attack them with a pick. Re-sand with 600 w/d or finer if you are picky.

This case is for a custom 1977 MX/Qualifier hybrid built from a 1978 125 Can-am “Fun Bike” which nobody knows anything about. Bombardier used the “Fun Bike” to dump old parts prior to the new 1979 models.

Bypassing the oil injection system

bombardier oil injectionThe only good reason for trashing your oil injection system for pre-mix is you have a rusty-crusty frame oil tank or the early model backbone oil tank foam is degrading. Here's a tech bulletin talking about dealing with the foam.

There are important provisos, however. The stock ignition side main bearing will have to be modified or replaced. The factory main bearing had a seal-like oil sling plate which was oil directing. That seal/bearing can be popped off. Replacement bearings will not come with this plate especially if you buy your bearings from the famous Tony Murphy at 661-944-1624 or

You’ll also have to drill an oil passage down to the right side crank bearing. My super mechanic friend Sam Niskanen lined up a drill that would make a hole through the cast webbing right into the perfect place on the bearing. I don’t have a bulletin on how to do this.

You could leave the oil injection pump in place to act as a plug or remove it and make an aluminum cover plate which plugs the drive gear passages. Do a little high temp silicone plug job where oil lines exited the outside cover to block dust/dirt or use a simple tube like above. From what I’ve read, it’s best to leave the functioning oil injection pump in place to avoid negative issue like premature wear and failures.

Make a Performance Rotary Valve on the Cheap

Let’s say you have a TNT and 1) want more poop or 2) you have a TNT or Qualifier that you want to get to MX performance. If want to move more fuel/air into you engine do this:

  1. rotary valve 2 thGo to Canned-ham's technical documents page. You will find this photo of MX, Q and TNT valves.
  2. Increase the diameter of any valve to 4-7/8”.
  3. Print out the full-size photo. Trim around the photo and you have a template. You’ll have to cut out enough of the middle to line up the center teeth too.
  4. When the template lines up with your valve, mark the new cut line. Hint: The right side of all valves is the same so you are only futzing with the left side.
  5. Carefully cut along the new angle line with a grinder and finish the new edges.

rotary valve 1

This photo shows a real MX valve on the right. On the left is a TNT valve I changed to Q specs.

Note: This would be particularly helpful for 125 and 175 engines as they are so close and used the same pipes in most models. MX engines had additional changes like compression ratio, porting and pipeage. It ain’t all the valve.

125 &175 Broad-range Tuned Pipes

The header length for the 175 is longer than the 125. That seems to the only difference. The stinger length was not specified on the drawings I received many years ago.

This drawing is incomplete and was not labeled 250 or short stroke, but I assumed that from the 125/175 drawing that came on the same sheet. Again, stinger length and diameter was not specified. You might plug 32mm diameter into your formula and see how that fits. This pipe applies to models prior to the MX4.

I can’t tell you the power characteristics of this pipe but you can assume it will have more poop than stock pipes. If you have a hard time reading specs after blowing the diagrams up, contact me to see if I can help.

Refinishing Can-am Tanks

I’ve got to refinish two early tanks. One is slated for a black 1977 Black Widow replica, the other a TNT tank to be painted 1980 MX orange for my ice bike. I’ve been on YouTube looking at various plastic reclamation techniques. I tried the knife blade trick and it was too slow. In desperation I grabbed the B&D Mouse with 150 grit and was amazed how fast the junk yard grime came off. I didn’t want to use any coarser grit because I am unwilling to chase the deep-down sanding scratches. The yellowed white plastic seems hard to clear away but no matter if you are painting. Next up is 180 and 230 then 400. I’ll keep you in the loop.

When I figure out the secret formula for a dependable, long lasting paint job on plastic, I’ll let you know. I know you must use a plastic primer. It’s been explained to me that this stuff is like spraying on a tacky glue finish that bonds the plastic to the primer once the alcohol fluid evaporates.

Hint: I recommend putting an in-line petcock in your fuel line. After use drain out the tank gas so it has less time to permeate through the plastic and lift your paint.
