There is a video on the internet showing a few bombardiers that have had their rear suspension modified by having the tires removed and replaced with a slider type suspension. One machine has only the sprocket and the one rear tire on it while some of the others use two tires per side. It is a very interesting video and well worth the look. It also shows an old 1939 B7 along with a few other interesting machines. Some have been cut down and used as flat deck type vehicles.
The video was taken in St-Roch-de-Mekinac, Quebec and looks like it is some sort of rally similar to the Cranberry Portage Rally.
I sent a request to the person that posted the video to see if he/she could post it on our NT site and am awaiting a reponse. As the video is from Quebec, we may have a language problem.
If anyone would like to try and view it, here is a few steps that will hopefully help.
1. go the Youtube
2. type bombardier snowmobile in the search box
3. click on one of the bombardier video
4. the one that is posted by fatssoalbert is the good ones. he/she has a few, but the one that is 4:45 minutes long is the good one.
5. if you click on his/her profile, it will show all of his/her posts and there are a feww well worth the look
There will be quite a few different video choices pop up with bombardiers, but the rally ones have some good machines. There is one there that appears to have all mag wheels on the rear suspension, but may just be painted.
Hopefully I will here from fatssolbert and inform us as to the suspension set up and perhaps send us some picture for posting on NT. It would be nice for him/her to join and past along the NT site to whatever club that happens to be out there.
The Quebec event appears to be the same sort as Manitobas with some prttey nice machines.
Good luck and hopefully you will enjoy this as much as I did.
