Yamaha Bear Tracker 2WD Breather Kit (4BD-11160-01-00, Ay50)

The Yamaha Bear Tracker 2WD Breather Kit (Part Numbers: 4BD-11160-01-00, Ay50) is an essential accessory designed specifically for the Yamaha Snowmobiles with a 4-stroke, 4-cylinder engine. This breather kit is engineered to enhance the performance and longevity of your Bear Tracker snowmobile by effectively managing the engine's crankcase ventilation.

This kit comes with two crucial components: an oil breather assembly (Part Number: 4BD-11160-01-00) and an intake silencer (Part Number: Ay50). The oil breather assembly is responsible for venting the crankcase gases, which helps maintain the optimal engine oil level and prevent oil dilution. It consists of a breather filter, a vent hose, and a breather tube. The breather filter ensures that contaminants are trapped before the gases exit the engine, while the vent hose and breather tube facilitate the smooth flow of gases.

The intake silencer, on the other hand, is designed to reduce engine noise by effectively quieting the crankcase ventilation gases as they exit the engine. This results in a more enjoyable riding experience, especially in quiet winter environments.

The 4BD-11160-01-00, Ay50 Bear Tracker 2WD Breather Kit from Yamaha is an OEM (Original Equipment Manufacturer) part, ensuring a perfect fit and seamless integration with your snowmobile. Installing this kit is a straightforward process, and it provides long-lasting performance for your Bear Tracker snowmobile.

In conclusion, if you are a proud owner of a Yamaha Bear Tracker 2WD snowmobile with a 4-stroke, 4-cylinder engine, the 4BD-11160-01-00, Ay50 Breather Kit is an essential upgrade that will help you maintain the optimal engine performance and extend the life of your snowmobile.
