A snowmobile includes a tunnel having an inverted U-shape, having top, left side and right side portions which at least partly enclose a space. A drive track is disposed around a rear suspension assembly and at least in part in the space. A first heat exchanger has a heat exchanger liquid inlet and outlet. The heat exchanger liquid outlet fluidly communicates with the heat exchanger liquid inlet and with an engine liquid inlet. The first heat exchanger forms part of the top portion and is operable to dissipate heat toward the space from liquid passing therethrough. A second heat exchanger has a heat exchanger air inlet and outlet. The heat exchanger air outlet fluidly communicates with the heat exchanger air inlet and with the engine air inlet. The second heat exchanger forms part of the top portion and is operable to dissipate heat toward the space from air passing therethrough.

Heat exchanger for a snowmobile engine air intake

A snowmobile has a frame including an inverted U-shaped tunnel having top, left and right portions at least partly enclosing a space. A drive track, operatively connected to an engine, is disposed around a rear suspension and at least partly in the space. An air intake system has a heat exchanger surface disposed in or adjacent to the space. Air flowing through the intake system contacts the heat exchanger surface to be cooled thereby before entering the engine.

A snowmobile has a frame including a tunnel, at least one ski, an engine having an engine air inlet and a drive track operatively connected thereto and disposed at least partly below the tunnel around a rear suspension. A heat exchanger connected to the tunnel has a heat exchanger air inlet and a heat exchanger air outlet fluidly communicating with the heat exchanger air inlet and the engine air inlet.

An adjustable handlebar riser assembly has an outer member, an inner member, a pin, a retainer member and a locking member. The inner member and the outer member have mating flat-bottom V-shaped faces. The inner member slides at least in part within the outer member. Each of the outer and inner members has at least one aperture through their flat-bottom V-shaped faces. The pin is inserted in an aperture of the outer member and in an aperture of the inner member. The retaining member is connected to the pin at one end while the locking member is connected to an opposed end of the pin. The locking member can exert a tension on the pin, pressing the outer member onto the inner member for locking these members at a selected position relative to one another.
