- 1970 Moto Ski Grand Prix 634 --- Original
Serial # G8H 701021
This snowmobile was made by Bouchard Industries (Giffin Corp) in Quebec, Canada
The Grand Prix model was a premier model with a gold metal flake hood and gold-colored engine and chassis.
Powered by a 634 Hirth engine, the largest power plant offered that year.
Very fast. See the drive-up segment of this video.
This example is largely original. The seat was recovered and a new windshield was installed. Beyond this, a great as-built original. Some surface rust.
I doubt that there is another person in the world that knows the complete history of every make and model like this man, Valdi..
We sold them ,and I worked on them and raced a 634 , 438 , and the 340 Grand Prix . And took a 634 and put on a 70 Zephyr for cross country racing. Ran oval , drag , and cc. When Moto Ski was bought out by Ski Doo we quit selling them but fixed and repaired sleds till we were out of parts . And I also raced for a uncle that sold Ski Doo and Boa Ski . I had the best world for a teenager at the time . Now 67 and miss those days .
I have a 1977 john deere 340 cyclone. I found out john deere was the winning sled for about 5 years which does not surprise me annd my sled came from thst era. I just found out that If you bought one of their machines and wanted to race the company had its own race team and pit crew for any customer who wanted to race! So if you had one you were sponsered and on the team! That is confidence in a product we dont seem to see anymore.
Absolutely beautiful machine! In the mid 70s, Dan Wark moved his family to my hometown in Gladwin Michigan and started the Wark Sport and Machine Shop next door to us on the Tittabawasee River in the White Star/ Wooden Shoe Village area. They sold and serviced Moto-Ski machines. Great snowmobiles and very fast. R.I.P. Dan and Rosie,gone but not forgotten. 📕
Awesome Sled....WOW...
Super cool hood and front lights . A total snow classic who's manufacturer had television adds showing their machines being ridden in dried up , rocky river beds at high speed taking a brutal pounding and not breaking. That commercial really stuck in my mind . Whenever i hear moto-ski that image pops back up !

The thing is that every single older sled needs a new windshields and seat covering...still original in my book
Wow that's awesome thank you for sharing, mint sled
Nice machine, our family had moto skis growing up in northern VT
very nice! I have a 1969 ski daddler with the same hirth 634.
Hirth made and sold a pile of those big fan cooled engines.
Take it easy. Like your vid’s but that tree came up fast lol. Stay safe.
Great machine
1969/1970, Moto-Ski had a SM760 model. They were very fast.
That thing is a badass
That was sincerely incredible to listen to, I find myself getting more and more fascinated with the topic of the old machines each day. Since you said you lived in Minnesota have you by chance heard of the Ridge Runner Twin tracked snowmobile?
I had a 74 TS400, last of the BSC motors.
In1975 they had the rotax motors.
Ihad a 70 340 and dad had the 71 634 both Gran Prix
Good video,... now you better get out of that backyard,... so those blackbird's can have it back,... they sure sound mad,... nice Moto-ski though,... I think our neighbor Jack had one that was called a Zephr,... big single cylinder (Hirth),... HD tillitson and 24 hp,... it was pretty close to our "71" 340 tnt Ski-Doo.........
SKI-DOO 775cc TNT
Is that the pulley rattling?
Not sure but I think JLO had a 760cc in 70 maybe 71.
Edit: hated the 634 cause coils were under engine and the recoil rollers and cage always problematic.
Jello motors got hot and the base seal popped out.
Does anyone remember the Dauphine snowmobile my dad had bought 3 for our family to ride, I still remember the 634 Hirth SS model Dauphin had beautiful purple and white machine !
For 634cc it was a dog. 36 hp
I was going to ask about HP. Did any mfr manage to get more ponys out of it? When I was a kid someone let me try a 634 Rupp across the field. I thought it was a rocket but I was riding a 12/3 Oly at the time.
