I heard the 71 ski doos are made a little thin, tunnels crack, but that makes them even lighter. But besides rust, these sleds do seem to hold up good.
I think there maybe two different Chinese companies that make clone Honda Trail 70's minibike that can be bought for a few hundred dollars. Here is an example of a relatively inexpensive snow sled that would make for a good clone. I owned a 1973 Ski-Doo Elan 10hp I believe and it was a blast to drive in the snow.
I want to put a 20hp Briggs or predator in my 71 Olympic so then I’ll have a 4 stroke with electric start. A small v twin would be cool as well but would like to keep the weight down.
@@Trikekid84 Interesting thought but you just know there's a good reason all snow sleds are 2 cycle. Drove sleds for about 6 or 7 years some 40 years ago and I hated having to mix gas and oil. I think it was Yamaha that came out with the first sleds that you didn't need to premix you just added oil to one reservoir and gas to the gas tank. I'm sure they are all engineer that way now. I am from the Fred Flintstone era of snowmobiling. Extremely simplistic, but cheap and affordable.
@@dampkring100 the rear cogs seem to last longer because they are a different type of material, and it’s a lot less work to pull the rear axle out than the front so I’m still running them.
Yeah it can pivot over terrain, there is only a cross shaft where it bolts to the tunnel, the shaft that the wheels are on is just hollow with a bearing pressed on.
I remember going through bogies springs from breaking and we finally changed out to a heavy spring that hardly ever broke. We use to beat the crap out of these little sleds and they would just keep going and going and going.

Great job! Thanks for the detailed explanations throughout, really helps
Well done !
Now, this Ski-Doo is good for another 50 years of service.
Powder coating, interesting! Thinking about t.v and the hooks! That paint and process makes for good parts! Ding
Nice work. They made these old sleds pretty tough that there are still so many around. Guess we're all waiting for snow...

When doing a restoration. Always change the rear axle rubber cogs. Don't ask why. 😌
Wasn't really a restoration, just a repair at this point haha.
@@Trikekid84 the point of replacing the rear cogs too,went right over your head.

Do the bogey systems rotate on the shaft as well as butterfly for a lack of a better term.

Nice video, was wondering where you got the drive sprocket mounting plate?

I’m redoing my bogies and wondering where the one with only one wheel goes the rest of the shafts have 2 and this one has 1 in the middle
That's the very front one. Only the elan did this, Olympic, Nordic, tnt all have four per set.

Where was chain tensioner
The 10mm bolt on the face of the chaincase, its spring loaded, it just bolts in. Easier to install when the chaincase is out.

Now watch the engine will blow up first bar run. 😂🤦♂️
the music is annoying. dislike
