Yamaha RS90PB, RS90PLTB, RST90B 2012 RS Vector Venture Owner's Manual

Regular maintenance includes checking and changing the oil, inspecting the spark plugs, examining the drive belt for wear, lubricating the suspension system, and inspecting the brake system. Refer to the owner's manual for detailed instructions and recommended service intervals.
First, ensure that the fuel tank is not empty and the battery is fully charged. Check the spark plugs for fouling and replace if necessary. Inspect the fuel line for any blockages and ensure the ignition switch is functioning properly.
To improve fuel efficiency, ensure the engine is well-tuned, keep the air filter clean, use the recommended grade of fuel, and drive at a steady speed. Regular maintenance will also help in optimizing fuel usage.
Common issues include starting problems, track alignment issues, and suspension wear. Regular maintenance and inspections can prevent most issues. Address starting problems by checking the battery and spark plugs. Track alignment can be fixed by adjusting the track tension, and suspension issues may require lubrication or replacement of worn components.
To adjust the track tension, lift the rear of the snowmobile and loosen the rear axle bolts. Adjust the tension bolts on either side of the track until the desired tension is achieved, then retighten the axle bolts. Ensure the track is aligned properly after adjustment.
During routine checks, inspect the suspension system for signs of wear or damage, ensure all bolts are tight, check for leaks in the shock absorbers, and ensure the suspension arms and joints are properly lubricated.
Spark plugs should be inspected every season and replaced every two seasons or 3,000 miles, whichever comes first. Always refer to the owner's manual for specific recommendations based on usage and conditions.
It is recommended to use high-quality 4-stroke synthetic snowmobile engine oil. Always check the owner's manual for the specific viscosity and brand recommendations.
Check the coolant level and refill if necessary. Inspect the radiator for blockages and clean it. Ensure the water pump is functioning correctly and inspect the cooling fan for proper operation.
Clean the snowmobile thoroughly and apply a protective wax coating. Drain the fuel or add a fuel stabilizer. Remove and store the battery in a cool, dry place. Lubricate all moving parts and cover the snowmobile to protect it from dust and moisture.
