snowmobiles

[LHF2019]

That's faster then I would've thought.... I also think off the start a bike is no match but ya deep snow you don't get near these kinda speed... I find snowmobile speedo are way off in general and there are so many variable even between the same sled, so these are more approximation then anything else but sound about right to me...

I always said after 100 mph nothing changes just takes longer watching the needle climb.

I always said "nothing good happens after a hundred"

Deer for all seasons:

The only real disappointment with the 4110 in the background was its inability to lift vintage sleds "the long way" (with fork tines running under the running boards). Just doesn't have enough ompph to do it with snowmobile's engine weight located that far out from the pivot pin. Put the sleds on pallets and lifted the short way. Made stacking the sleds on the 2nd tier of a garage platform a bit of a workout.

Not a fast sled seen here. That is me operating it.

I wouldn't mind getting my hands on expedition or a scandic...

I'm not sure which way you mean "Lead". Were they always out in front, or a lead weight like you use for fishing? I do recall that they were one of the first liquid cooled sleds, although the JD Liquifire was right behind them.

Edit; I just answered my own question.

1974 Mercury Sno-Twister

When the history of snowmobile racing is written there will be a select few sleds that will be recognized for totally dominating the competition. The 1974 Sno-Twister was just such a sled. It arrived at the time when Mercury Marine had decided to go racing after manufacturing sleds that had...

This thread has gotten me to search out vintage sled sites and articles, and brought back some good memories.

My Nemesis was a 340 Sno Twister at Radar Runs

After graduating from a 1980 3500 Citation, to a 1979 300 Enticer, I wound up Twisting Wrenches at a Doo Dealership, bought a 1981 7500 Blizzard in a box.

Found a Doner 1980 354 Rotax, nicely Craved and Polished (Bosch Ign) and started working on it for Radars Runs. The Polaris Dealer's Tech had a 76 340 Sno Twister, and it would be me and him at every run. The thing looked like it weighed 1/2 of the Blizzard and was probably short 10-15hp, but it was quick, especially on Colder days.

I recall, leading 1 event most of the day. Putting down a run 3 mph faster than he could get, and before the track got chewed up. Close to the end he beat me by 2 mph.

I went over and asked "Where did that come from?" He said "I dropped 5 Sizes in Main Jets" A Rotax wouldn't have even started, (pun, but they liked Rich)

I never got into snowmobiles but I always wanted to challenge my friend to a drag race against my CBR. Problem was finding parallel road and field long enough for the challenge.

Stock 800 or 1000 sled? With perfect grip the sled might win the 100 yrd dash, but after that it should be all bike. Big engine drag sleds are a whole different thing though, those are quick!

Our one & only snowmobile we had in my childhood back in CT in the '60s was a 1964 Larson my father bought/traded for. It had an 18 hp 2 stroke. It was tough to get it going good with me and my friend Jim on back if the snow was deep. I used to pull him around the pastures on his snow skis until he snagged a looped piece of barbed wire one time and face-planted badly. During warmer weather I jury-rigged some lawn mower wheels in place of the skis and we rode around the field out back some but it wasn't comfortable and the wheels didn't last long either.
