Picked up this sled in unknown condition, but when the price is right you don't ask questions! Turned out to be a 1985 Formula MX, and it's actually in pretty decent condition. The 470 rotary valve engine needed a little bit of loving.

Great job bringing that barn find sled back to life! I've done the same with sleds, boats and cars. Something very satisfying about restoring something vintage that has good bones but doesn't look great and bringing it back to life! Well done! Love you're style.

My uncle bought this sled in 86 and I grew up ripping around our ice traps. In 96 I bought it and rebuilt the engine I was 16 then won my first trophy at a 1000 radar run. Beat a 500 by 1 mile an hour. Lucky my friend's 84 Phazer had a can and couldn't run in stock class he beat me by 6mph. Went to cats from there.

The Blizzard MX was still in production for 83/84. Doubt many were sold by then though. 83s looked just like the 82s, but the 84s were black like the 9700s. I actually have an 81 Moto Ski Grand Prix Special MX, which became the Sonic MX for 82. I’ve seen some others around on the internet, but supposedly not many of them were built. They didn’t even show up in the 81 advertisements.
@toocheaptosmoke

Interesting, never knew they kept them in production that long. Had read some articles about the formula mx release being delayed, I think in '84 they had the SS25 or something that had this engine but leaf springs up front?

I consider you an expert in vintage snowmobiling. My first sled experience was with an Allied. I think made in Minnesota. Then Polaris mustang. Then a Wildcat. It was the top in my opinion.

Great on groomed trails but hang on tight when you get in the rough stuff. Also have an '85 Safari with the same rear skid; basically the same chassis with a 377 and no tunnel coolers. And both my '89 Mercury Grand Marquis and '04 Chevy Express 3500 have functioning factory tape decks.

It's a shorter 114" w/ 1.97 pitch track, can use 15" or 16.5" wide versions. There were blizzards and citations that used a similar track, a newer 121" track would need suspension and track driver mods.
