Here is the production numbers of the Liquifires of that model type.

There were 1175 made. Hard to tell how many are left in barns and back yards these days! You don't see many 78 340's on the snow anymore! A good one to restore and ride.

Looking good! You will have it ready for next season.

Wow, that is one clean sled. Great find.

For the oil, those came in 6 packs. When you got a case, they came in 4 - 6 packs per box.

It looks just like the Harbor Freight lift but in Black. My HF lift is red and looks exactly like it.

Nice work!! One of these days I will get to mine.

Welcome!! You get to have fun working on it. Then fun riding it!

I would leave the heat exchanger as it is. My Ski Doo's have a finned exchanger like this and I have never had any problems with it. Unless you are going to ride in low snow conditions on dirt roads, everything will be just fine.

I have seen those springs on the 76-78 sleds. Someone welded a spacer in there also to raise the front end some that should not be there. The 80-84 sleds used a single spring.

Just to clarify when you are looking for parts. It sounds like you sled will be a 1980 Liquifire. They did not make them for the 79 model year. The date stamp on the tunnel will show a manufactured date in the summer of 79, but they are an 80 model year. This throws people off. I do like Nick does o...

Just got mine in the mail yesterday! It is great!!

The TR800 only came on the 82 and up Liquifire. The 80/81 Liquifire, and all years of the Trailfire and Sportfire used the 102C.

It is different. The Sportfire box is a different shape and does not use the rubber carb boot.

I put this search out a few years ago. Thought I would ask again. I am still looking for one.

Thanks!

You can check to make sure it will run first like listed above. But, if it were my sled, I would change out the seals before really running it just to be safe. I have two trailfires, a sportfire, and a liquifire to restore. They will all get new crank seals before I even think of starting them up. T...

No. The ski stance is built into the front frame. It is not like a modern day sled where you would just change the A arms. You would have to fabricate something if you wanted widen it. Way more work than it would be worth on a 40+ year old sled.
