I've looked everywhere to try to find some information on it. My stepdad and i collect vintage snowmobiles and came across an 81 blizzard 9700. i have had a couple blizzards but none like this, it has a 9700 much bigger and faster then the 9500. we took it to the radar runs and it did 96mph in 1000ft. pretty good for an older sled. I would just like to kno a little about it. Was it a special order sled from ski-doo or what. I've never seen another one and can't find one on the internet anywhere, i'll try to get a picture of it tomarrow and i'll post it.
