    Abstract: Embodiments describe a method of controlling a two-stroke internal combustion engine. A method of controlling a two-stroke internal combustion engine includes determining a base nominal exhaust gas temperature, determining a base barometric pressure correction to base nominal exhaust gas temperature, determining exhaust gas temperature differential, determining exhaust gas temperature injection correction, and utilizing the exhaust gas temperature injection correction to make a final short-term fuel or ignition correction.

    Abstract: A braking system for a snowmobile includes a track driveshaft and a splined spacer. The track driveshaft has an outer spline and is formed from a first material. The splined spacer has an inner spline and an outer spline. The inner spline of the splined spacer forms a splined connection with the outer spline of the track driveshaft such that the splined spacer is coaxially positioned about the track driveshaft. The outer spline of the splined spacer is configured to form a splined connection with an inner spline of a brake rotor. The splined spacer is formed from a second material that is different from the first material.

    Abstract: An exhaust system for a snowmobile includes a muffler housing, the bottom end of the muffler housing including a muffler exhaust outlet configured to emit exhaust. The exhaust system includes a muffler housing cover spaced from the muffler housing to define an airflow channel therebetween, the muffler housing cover forming a bottom opening. The exhaust system also includes a gas combiner at least partially surrounding the muffler exhaust outlet on the bottom end of the muffler housing and extending through the bottom opening of the muffler housing cover. The gas combiner receives air from the airflow channel and the exhaust from the muffler exhaust outlet to emit a combined air-exhaust stream.
