Can-am Vintage Bikes

can am bike disassembledBack when I was in my 30s I was big into Can-ams and Maicos even though I was a flat tracker. 45 years later I’m back into Can-am. I even have plans to start vintage MX racing next year at 75--we’ll see. $225 got me back in with a Craigslist ad showing this 1979 Qualifier. It’s in pieces but slowly coming back together. I’m rebuilding it as an 80 MX. Last year I bought a bunch of parts and from from Mark Schrapel in southern Minnesota-Mankato. From his parts I’m going to make a 1977 125MX spider which they never made. The frame and engine turned out to be a 1978 “Fun Bike.” I think it was a way for Bombardier to dump a bunch of pre-1979 parts before the new line came out.

I tell you this because getting parts is a challenge. This section of my site will be to 1) offer parts others don’t have, 2) share information I’ve learned, 3) give you a list of all the suppliers I am aware of and 4) do a photo series of my builds-which may give you ideas.

Report 6/28/17

I have nothing to report because my attention is on building a Sportster into a Hooligan to go racing. AND building a Ski-Doo 600 MXZ for winter. And building a Briggs mini bike for racing too. AND finishing an ice boat. You know how it is don’tcha! I now know how few months of nice weather are left so the Can-ams are going to be winter projects

Can-am builder ideas

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 of 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. There is one important proviso 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 tmurphy440@aol.com.

I guess you could leave the oil injection pump in place to act as a plug or remove it but it is easy to 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.


can am frame 1Well it looks like I start with the 1979 250 Qualifier which will re-enter life as a 1980 MX. That explains the light orange color. Not hard to do with the commonality of parts. The next mission is to rebuild the stand higher so I’m not bending over so much. When I drop the engine in you will be wowed because it is totally tricked out.

can am adHere's an ad I did years ago when I was Omar's Dirt Track Racing. That 250 Can-am in dirt track trim had black screws and you could lay it over like a Russian speedway it stuck so good. I still sell dedicated ice fenders, but I redesigned them.
