The sled below belong to :

Adam Jacobson.

1975 Sno*Jet SST 440, slightly modified.

A few inches were added to the hood to fit the 500 Rotax inside. A custom motor mount was made, an oversized Mikuni is used to feed this beast, and has a modified Yamaha Phazer pipe.

The sled features a 133" Polaris Track with 3/4 inch lugs and custom brackets are used for more clearance under the tunnel.
