1969 olympic nordic. also made it in 1970

You are right. But it was just called Nordic. It has a 18” wide track. The Olympic has a 15”. We had a 69 and a 70’ Olympic with that 399cc engine. 24 hp. The ‘70 even had electric start!

You guys know the oil -gas mix rate?

It is a 1970 or later. The 69 Nordic was a 371 cc and was yellow on the lower half. We had one and ran the bag off it

Mixture was 20 to 1 and that remained unchanged when changed to a 399.

Hmm, our 69 Olympic was a 399. I cant remember what cc the 18 hp,’69 Olympic was. It was a single lunger. Ya, the 399 was tough all right. My brother and I put a zillion miles on er. Lol

 

[HotShotHarry]

Oops, 52week is right about the 371. We had a 70and a 71. Not 69 and 70.

This is a twin cylinder. Is the serial # stamped on frame somewhere?

I have a 399 Olympic in show room condition with factory ski doo cover. Still has the sold sign on the key. The paint isn’t worn off the the bottom of the skis.

This link might be useful. http://www.vintagesnow.com/Ski-Doo_files/1970-1971_skidoo_SM.pdf

The 69 Olympic I recall was a 320. 1970 was a 335. The link shows many other variations

I don’t have any pictures. Should clean it up and take some. Got no plans for it. Just a space waster in my garage. My wife loves the old sled so I can never sell it, her dad bought it years ago for $40.

This is my buddy Steve's Ski-Doo, his dad bought two of them brand new for him and his brother [I think it's a '70]. His brother's is now a parts sled.
Doesn't ride it very often, steers like crap...need to bounce off curbs to make it turn, lol.
He has a Yamaha 1000 something he rides regularly...
