New snowmobile at 90%, I recovered elements of the Small-Doo M and I transformed everything (almost as much work as starting from scratch)
Tank to be too long we will go to the maximum, Conquer 2.8 '' X 174 '' track, 5 lbs lighter than my previous 153 'crawler. I changed the last third of the pallets for more flexibility (so it was less likely to dig)
New rear suspension, sturdy all-aluminum arm, self lubricated nylon busshing, lateral rotation of 10 to 15 degrees over the entire length of the suspension, not just at the rear like other ...
33.5lbs, the same weight Nexteck carbon fiber suspension at $ 5,500 USD, but the latter must be stronger than mine.
I bought myself a paint powder coat, a lot more beautiful than aluminum color and does not oxidize.
Quick opening cover in 3 parts.
Front of the tunnel which marries the caterpillar, to be able to turn back the motor of advantage.
No choice to put the exhaust behind the chain, everything is very tight. But there is always a way to disassemble the engine head without leaving anything else.
Under the tunnel covered with UHMW non-stick sheets, no snow ice, less weight
Carbon fiber panels in places where friction or shocks should not be important.
Electric starter with 2000A lithium cell battery, adds 6.5lbs instead of 20-25lbs for a conventional starter.
Front suspension with spheres joins and ball busshing homemade in the shock absorbers to ensure a large suspension travel with this configuration. Although this configuration is not the best in the bumps, I have retained it because it reduces the wheelbase compared to double-wishbone arm, then its strength weight ratio is better (less material required for its manufacture , if frontal impact it will be cashed in a straight line or instead of being transferred by leverage towards the center of the chassis)
Walk narrower feet for less resistance in the snow and easier to put a foot on the ground.
The entire triangulated structure serves to support transmission, driven, brake, more solidly than it takes.
Even block engine 460cc, with an improved head thanks to my flow bench, I will try to see the air fuel ratio directly on the ground instead of the dynamometer. I can already estimate the maximum power and speed with the flow and the compression ratio.
I have other innovations to make and things to add that can be done after. It was urgent to try it, there is a lot of snow.
