Yamaha BR250TZ 2010 Bravo Owner's Manual

Regular maintenance tasks include checking and replacing the engine oil, inspecting the drive belt, cleaning the air filter, checking the spark plugs, and inspecting the brakes and suspension components.
If the snowmobile won't start, check the battery connections, ensure the fuel tank is filled, inspect the spark plug for wear or fouling, and verify that the kill switch is in the 'Run' position.
It is recommended to use Yamalube 2-S or a high-quality 2-stroke engine oil that meets or exceeds the manufacturer specifications for the Yamaha BR250TZ 2010 Bravo.
The drive belt should be inspected every 500 miles for wear and proper tension. It should be replaced if there are signs of fraying, cracking, or slipping.
Remove the air filter from the housing, wash it gently with a mild detergent and water, allow it to dry completely, and then apply a thin layer of air filter oil before reinstalling.
To improve fuel efficiency, ensure the engine is properly tuned, maintain the correct tire pressure, reduce idling time, and regularly clean the carburetor and fuel system.
Common signs include difficulty starting the engine, rough idling, reduced engine performance, and increased fuel consumption.
Adjust the suspension by setting the shock absorber preload to suit your weight and riding style, and fine-tune the damping settings for the terrain conditions.
Check the brake fluid level and condition, inspect the brake pads for wear, and bleed the brake lines to remove any air bubbles that may be causing the spongy feel.
Clean the snowmobile thoroughly, add a fuel stabilizer, disconnect the battery, and store it in a dry, covered area. Consider elevating the machine to prevent flat spots on the tracks.
