Do you have a service manual? Visit you local Authorized Ski-Doo Dealership for advice and to purchase a service manual. Do you have any information on what model it is, ect.? On the right side of the sled above the runningboards, check out the plate with the year, cc siza, VIN, ect.
Rotax named all their engines by 'type' (type 643, 809, 454, etc) THis doesn't necessarily mean CC's, although it's usually close. There should be a small ID plate on the recoil that will have this info...Finding out exactly what motor you have will help in finding specs...
Is it an 83 year or does it say 83 on the tunnel? - that would mean it's an 84 model.
It's got a 462 - it could be an Everest liquid. Is the hood yellow or white? - It could be an 84 SS - that was the first year for the safari chassis and they stuffed a 462 liquid in them too.
A 462 liquid with 1 carb would make around 60hp Id say. With twin carbs they make close to 70hp.
Well it must be a 84 ss/25, Also it has the single carb, how hard would it be to change that to a dual carb or would it be worth the hassal. Sorry i am new to this and don't know much about snowmobiles.
I know the sled is really no good anymore, but i am using the engine in a go kart chassi i have. Thanks for the info on the sled.
If I'm not mistaken the 462 cc motor in the MX was a Type 467. The 462 used in the SS & Safaris was not a 467.
How many acorn nuts on the head? I think the lo po motor used 8 while the hi po 462 & 521 motors used 12 (I think).
The other difference (not visible) is that the lo po 462 used 8 long studs to hold the cylinders & head to the case. While the other motor used 4 studs to hold each cylinder to the case, then the head was held onto the cylinders w/ 12 (I think) studs.
