Also do you know of any Can Am Bombardier forums out there? All the ones I find are either out of use or for the modern stuff.

Tim do you need the short stroke of the long stroke bottom end?

Still plugging away at the bike currently making a speedo mount its complete overkill i didn't like the normal ways of mounting it.. I have gone for a Daytona Asura Multifunction Gauge. http://www.digital-speedos.co.uk/new-da ... -701-p.asp

I needed to hack some bits off the Fazer 1000 top yoke first. So stuck it on the mill i should have taken the hack saw to it first took ages.

Loads of swarf.

So time to design a mount.

Knocked up the gauge profile in a program called Fusion 360.

Rear view

Will fit in this

Made a rear mounting part for it this will attach under the yoke.

I am not sure, I didn't realize that here were different bottom ends (short & long), do you know how I can tell which type I have. what difference does it make?

Regards,

Tim.

I have had 3 bikes now that have the MX engine with 61mm stroke this is the MX5 engine from the Motocross bike.

Army Bikes should have the 57.5mm stroke. Why this is i don't know i suspect it was supply problem of the Army/TNT engines at the time. They have all had the correct rotary valves.

I will have a measure. I suppose I can use a bit wooden dowel down the spark plug hole. Do you have any engines (complete or bottom ends) that you may want to sell. Regards,

Tim.

There was a listing on eBay for two and a half engines (three top ends and two bottom ends all orange in colour) that I stumbled across but I can't remember what it was listed under but might be worth looking

May be a red herring in the context of the engine stroke question but aren't the MX motors pre-mix? The Army motor is certainly oil injection.

I should have mentioned they are still injected and have the different crank.

I have at least 6 engines. They all need stripping and overhauling.

You will be better off getting yours rebuild. They are old engines now and all of them need new seals.

Minter does a nice Can-am engine rebuild after seeing MrShineys

Another photo heavy update more on the speedo mount. Currently about a month behind with updates.

I have a good stock of used aluminium i have quite a few large bits of this. It's take a while to cut.

Trimming to size.

You end up with something like this.

Trimming the end to size

I now need to find the centre did a bit of marking out.
Image

I used a centre point to align it up.

Now the fun begins.
