Awesome thread! Great idea and great pictures. Thanks.
PS how did those guys survive? More than 1 on the hill at a time and I can't tell for sure but I didn't see beacon, probe, and shovel. No back packs with survival gear, no extra gas, and no one drinking beers....geeesh it must have been boring!!!!
Before that I think they were called a RV!Buddy had a oval racer with a 250 engine or something crazy small like that but strung right out!I was like 9 or 10 when I saw it but remember it would go like a raped ape but almost always get towed back to the yard!!1979 Moto-Ski Super Sonic 340 LC. This was the brother to the Blizzard 6500? if I remember right. Same as the Ski-Doo but with a Moto-Ski name/color. Kinda like GM/Chevrolet trucks. The last of that group of three Super-Sonics was still kicking around in someone's shed about 5 years ago, but I have lost track. The last time I actually saw it run in the mountains it had a 521 Rotax, 124x16.5" track and 2" paddles. Outclimbed everything else we had at the time, that was probably 20 years ago now. They did tons of mods to those things to make them reliable and work.

Okay, gonna try and remember all the details on Dad's old sled and how it ended up.
1979 Moto-Ski Super-Sonic 340.
- 340 replaced with a hand-ported/polished 440 Rotax, 340 twin pipes. Bored carbs (36.5mm?) This motor ran head-to-head with the 505 big-bores of the day.
- Gutted muffler
- Comet Clutch
- Updated Ski-Doo secondary for durability (had a LH side chaincase setup, the '83ish scandic driven pulley was the last one to make it on his sled eventually)
- Hand-made outside-air intake system (prevent vapor lock)
- Fuel pump moved to a hole in the bulkhead to be cooled by snow. (again preventing vapor lock)
- Cut and tapered tunnel (first one we know of in Western Canada)
- Chaincase/Driven Pulley to Motor brace (sound familiar? LOL)
- Chaincase to frame brace
- Boxed in the upper portion of the front bulkhead to prevent bulkhead twist/cracking, stabalize motor mounts.
- Visible in this picture is the full-wrap front bumper made out of thin mild box-section steel. This was built to help protect the fiberglass bellypan and to help pull out of the snow. The jig for that was still kicking around 10 years ago and Dad finally threw the jig out.
- 114x16.5x0.5 track, stock.
Sled was sold in the early/mid eighties. Lost track of where it ended up.
after alot of digging their might have been 3 build....I had one! here are some pics....the work was incredible...it seemed a new tunnel was built in factory after hours in the Race department......mine had the 521 with a fancy fiber glass intake to bring in cold air.....I wonder if mine was yours? I have not heard anymore about the other 2 but the rumor was 3 were built.
I have more pics of sled.....ask your dad if it looks like it was his? mine had a 521 but sold it seperate from the sled!
