    so a good friend just gave me a 1977 can am 250. it appears to be a mx3. the motor is stuck and the front wheel hub is shattered. thats the worst of it. its got a cool preston petty headlight fairing with a p277 stamp on it, neat, it seems pretty solid and complete. impressive build quality! magnesium everything, alloy seat pan and a big sticker on the gas cap that says competition use only, no warranty applies to this model.
    stored inside for 20 years or more. cdi ignition! looks aftermarket? mototek model cd40. anyone have any info, thoughts... id love to hear more about this burly looking rig

    thats just from cleaning it up! but give her a while she'll probably leave a spot. i have the sickness, i have too many and too many are projects like this. my buddy just called and said he has got the airbox and a different can am tank for me, i dont know how the hub broke because the hoop actually looks real good so maybe something broke inside and it grenaded? the exhaust looks really solid and im not sure the rear fender is right? school me? i asked to have the thread title contain the name, so maybe someone will have some info on this:ear

    The photos are great!! They speak to me... They say they want to move to Idaho and get a spool hub transplant.
    The result would make it the basis of my next shorttracke project!!!:evil

    cant find much info on this bike but after finding this i may have to keep her...this is copied from canned-ham.com

    the MX-3 included key developments in suspension, with Can-Am following the trend with laid down shocks and greater fork travel. Marzocchi forks replaced the Betor at the front, with an extended swing arm at the rear, improved overall suspension travel.

    The 250 model of the MX-3 was known as the Black Widow. The bike produced over 35bhp, with the small tubular frame and swing arm struggling to handle the power. Produced for a single year, it remains one the most sought after collector models.
    The Legend of the Black Widow

    The MX-3 250 is known as the Black Widow, but you won’t find that name on any sales brochures. The reason why goes something like this:

    The MX-3 was produced at a time when the thought of making bikes was already starting to wane at Bombardier. The bike was built on limited budget, as Bombardier had refused to invest the money in a new chassis. Laying the shocks down has already been tried by other makes and in a desperate try to keep up with the ‘70’s suspension chassis race, Can-Am followed suit.

    In the early test stages Jeff Smith reportedly looped the bike and refused to ride it. Jimmy Ellis tried and after a hair raising practice session in which a spectator was serious hurt, declared the bike “a black widow” – meaning it was lethal. Unfortunately the French Canadians took the declaration as a seal of approval (assuming Jimmy meant the word as an antonym) and commissioned special decals for the rear fender. But the American dealers took exception to them and stripped off the decals, with Bombardier being forced to issue a recall notice to remove them.

    But by then, the name had stuck. The Black Widow is now the most desirable of any collection. And yes it’s still as lethal to ride!

    ive gotta think on this one for a while, some info i found says the mototek cdi was sold as a dealer installed option.... this one may be hard to part with all of the sudden. what causes the hubs to break like that? if i do end up selling youve got 1st dibbs.

    I think there were a few magnesium hubs that did that kinda stuff back in the 70s. In those days they built everything to be as light as possible then strong. I am willing to bet you'll find a spare easy enough.

    Ive got a few parts here for a Can-Am,I think its a TNT though which was the street legal version. I once rode a works model 250 Can-Am years ago. It was reputed to be an ex Marty Tripes bike. Every nut and bolt was titanium,the frame was a one-off no oil in frame skinny tube looking thing,special hubs,etc.
    2 friends looped the thing hard,one in 3rd gear,one in 4th. I figured out when I rode it the trick was to keep the rear tire lit,dont let it hook up or it would flip very quick. It ran like a big chainsaw with no flywheel effect,instant revs and revved to the moon. The rotary valve engines are easy to get big power out of. Not the best handling thing in the world.
    Parts are getting a little hard to come by.

    The "Black Widow"

    Have you taken a look at www.classiccanam.com ??

    Some of the info might help, it's getting kind of dated, but there may be some links that help...

    Good luck with the build!

    keep it, sell it, keep it, trade it..... too many projects and not enough time or money to finish them. so im going to steal the fairing and send it off to ebay, hopefully someone can restore it to its former glory. kinda kills me to pawn off a rare piece of mx history but i cant even fit this into the "bikes ive gotta get to room". i keep messing up my back and i cant even come close to reaching the ground with one foot so my reasonable side, (which doesnt come around very often!) says this bike will hurt me. my back is telling me to listen. hopefully a fellow adv'er gets it and will share its journey with us:waysad
