Yamaha RS90GTA, RS90LTGTA, RST90A 2011 RS Vector Venture Owner's Manual

To perform a basic oil change on your Yamaha RS90GTA, first ensure the snowmobile is on a level surface. Warm up the engine to make the oil easier to drain. Turn off the engine and remove the oil drain bolt located at the bottom of the engine. Allow the oil to fully drain into a pan. Replace the drain bolt and remove the oil filter. Install a new filter, then refill the engine with the recommended oil type and quantity. Check for leaks and ensure the oil level is correct.
If your Yamaha RS90LTGTA won't start, check the following: Ensure the kill switch is in the 'run' position, the fuel tank has fuel, and the battery is charged. Check for any blown fuses and inspect the spark plugs for fouling or wear. Verify that the fuel lines are not clogged or leaking. If all else fails, consult a professional technician for further diagnosis.
To maintain track tension on your RST90A, place the snowmobile on a lift to elevate the track. Measure the track sag at the midpoint between the front and rear suspension wheels. Adjust the tension bolts on either side of the rear axle equally until the sag is within the specified range in the service manual. Ensure the track is aligned and test it by rotating it by hand.
The recommended maintenance schedule for the 2011 RS Vector Venture includes: changing the engine oil and filter every 1,000 miles, inspecting the drive belt every 1,500 miles, checking and adjusting the track tension and alignment every 2,000 miles, and inspecting the brake system every 3,000 miles. Always refer to the owner’s manual for detailed intervals and procedures.
To properly store your Yamaha snowmobile for the off-season, first clean the entire machine thoroughly. Add fuel stabilizer to a full tank and run the engine for a few minutes to circulate the stabilizer. Change the oil and filter, and lubricate all moving parts. Remove the battery and store it in a cool, dry place. Elevate the snowmobile to prevent track and suspension compression. Cover it with a breathable cover to protect it from dust and moisture.
If the headlights on your Yamaha RS90GTA are not working, first check the headlight bulbs for any signs of damage or burnt filaments. Inspect the fuse box for any blown fuses and replace them if necessary. Ensure the headlight connectors are secure and check the wiring for any visible damage. If the issue persists, consult an authorized dealer for further inspection.
To adjust the suspension settings on your RS90LTGTA for a smoother ride, you can fine-tune the front and rear shock absorbers. Most models have adjustable spring preload and shock damping. For a softer ride, decrease the preload and damping settings. Always make adjustments in small increments and test ride after each change to assess the impact on ride quality.
If your RST90A is overheating, check that the coolant level is adequate and that there are no leaks. Ensure the radiator and cooling fins are free from obstructions like snow or debris. Inspect the thermostat for proper operation and replace if necessary. Verify that the coolant pump is functioning. If overheating persists, consult a professional technician to diagnose and resolve the issue.
Yes, you can replace the drive belt on your 2011 RS Vector Venture yourself. Begin by removing the belt guard and then relieve tension by compressing the secondary clutch. Carefully slide the old belt off and compare it to the new one to ensure proper sizing. Install the new belt by reversing the removal process, making sure the directional arrows on the belt, if any, point in the correct direction. Reinstall the belt guard and test the belt alignment by slowly rotating the clutches by hand.
Signs that your Yamaha RS90GTA's spark plugs need replacing include difficulty starting the engine, reduced fuel efficiency, poor acceleration, and engine misfires. Additionally, if you remove the spark plugs and notice heavy deposits, wear, or damage to the electrode, it’s time to replace them. Always use the spark plugs recommended in the service manual.
