A vehicle is provided and includes a frame including a tunnel and a front portion, an endless track at least partially positioned within the tunnel, a ski supporting the front portion of the frame, a spindle coupled to the ski, and a front suspension coupled to the spindle. The ski defines a central plane extending vertically and longitudinally, the central plane defining an inboard lateral side and an outboard lateral side, the ski having a bottom surface and a keel extending therefrom on the outboard lateral side. The spindle is coupled to the ski at a first position on the outboard lateral side of the ski. The front suspension is coupled to the spindle at a second position outboard from the central plane of the ski.

A device for attaching to a ski of a snowmobile includes first and second spaced apart legs. Each leg has a ski engaging portion proximate a second end that is configured to engage a bottom surface of the ski proximate outer edges thereof. The device includes at least one wheel attached to the first and second legs between the first end and the second end and a cross bar that attaches the first and second legs proximate first ends thereof. The device includes a lever arm extending from the cross bar between the first and second legs wherein the lever arm is configured to be angularly positionable relative to the first and second spaced apart legs. A handle is attached to a distal end of the lever arm and has a surface configured to engage a tip end or a ski handle of the ski. The device includes a retaining member attached to the handle that is configured to engage the ski handle, wherein when the ski engaging portions engage a bottom surface of the ski and the retaining member engages the ski handle, the ski is elevated and the at least one wheel engages the ground surface such that the skis do not contact the ground surface as the snowmobile is moved.

A clutch alignment apparatus and method of aligning a dual clutch system in a continuously variable transmission that enables a user to measure the alignment of the primary clutch and secondary clutch when the system is under a load that is similar to that which is applied when the system is operating under normal operating conditions.

A snowmobile having enhanced steering control has driving control system including an electrically actuated device coupled to a steering system having a user operated steering element with the device applying torque to the steering system, a throttle, a plurality of sensors including a torque sensor and at least one additional sensor to generate terrain condition data and operational data, and at least one controller coupled to the device and the sensors. The at least one controller selects a terrain condition mode using the generated terrain condition and generated operational data, determines the torque to apply responsive to the angle and speed of rotation of user operated steering element, and operates the electrically actuated device to apply the torque to the steering system, with the torque being applied only by the electrically actuated device.

In some embodiments, a fuel rail for a two-stroke internal combustion engine includes a fuel rail body, a fuel inlet component integrated within the fuel rail body as a one-piece component and in fluidic contact with a fuel line, one or more fuel exit ports in fluidic contact with a cylinder of a combustion engine, and one or more fasteners adapted to secure the fuel rail body to a cylinder wall of the cylinder of the combustion engine
