Frequently Asked Questions (23)

  • Why won't my Yamaha Blaster YFS200S start?

    If your Yamaha Blaster YFS200S won't start, refer to the troubleshooting chart which outlines checks for the fuel, compression, and ignition systems:

    • Fuel: Check if there is fuel in the tank, if the fuel cock is in the correct position ("ON" or "RES" if needed), and if the fuel cock is clogged. Also, check for water or dirt mixed in the fuel.
    • Compression: Kick the kick lever to see if there is compression. If there's no compression, consult a Yamaha dealer.
    • Ignition: Remove the spark plug and check the electrodes. If they are wet, wipe them clean. If they are dry, attach the plug cap and ground to the chassis, then kick the kick starter strongly. If there's no spark, adjust the plug gap or replace the plug. If the issue persists, consult a Yamaha dealer.

  • What causes a Yamaha Blaster YFS200S to have no spark?

    If there is no spark, the troubleshooting chart suggests checking the spark plug electrodes. If they are wet, wipe them clean. If they are dry, attach the plug cap and ground to the chassis, then kick the kick starter strongly to check for a spark. If there is still no spark, you may need to adjust the plug gap or replace the plug. The Throttle OverRide System (T.O.R.S.) is incorporated into the ignition circuit, and if it fails, the spark plug will not spark. If this system is suspected, have it checked by a Yamaha dealer.

  • What type of fuel does the Yamaha Blaster YFS200S use?

    The Yamaha Blaster YFS200S uses PREMIUM UNLEADED GASOLINE ONLY with a pump octane number ([R+M]/2) of 90 or higher, or research octane number of 95 or higher. If knocking or pinging occurs, a different brand of gasoline should be used. Unleaded fuel provides longer spark plug life and reduced maintenance costs. If unleaded gasoline is not available, leaded premium gasoline can be used. Gasohol containing ethanol can be used if the ethanol content does not exceed 10%, but gasohol containing methanol is not recommended.


    For more information, see page 43 of the manual.

  • How do you properly ride a Yamaha Blaster YFS200S?

    To properly ride your ATV, it is essential to familiarize yourself with its operation and controls. This ATV is intended for recreational use by experienced operators only. Before riding, read the Owner's Manual and understand all safety information and labels.

    Key riding techniques include:

    • Starting and Accelerating: Release the throttle lever, pull the clutch lever to disengage, shift into first gear, then gradually open the throttle and slowly release the clutch lever. For higher gears, release the throttle, quickly pull the clutch lever, shift, then gradually open the throttle and release the clutch. Always close the throttle while shifting gears to prevent damage.
    • Decelerating: Release the throttle and apply brakes smoothly and evenly. Shift to a lower gear, ensuring the engine has sufficiently slowed before engaging to avoid loss of control or drivetrain damage.
    • Turning: Place your weight on the footboard to the outside of the turn and lean your upper body into the turn while maintaining an even speed with the throttle. Practice at low speeds first.
    • Climbing Uphill: Use proper gear and maintain a steady speed. Shift your weight forward. Never open the throttle suddenly or make sudden gear changes. If you stall or roll backwards, keep weight uphill, apply brakes, and lock the parking brake. If rolling backwards, apply the front brake and keep weight uphill.
    • Crossing a Slope: Lean your body in the uphill direction and correct steering by pointing front wheels slightly uphill. If tipping, gradually steer downhill to regain balance.
    • Crossing Shallow Water: Drive slowly and carefully through water up to 35 cm (14 inches) deep. Check for obstacles and test brakes after leaving water.
    • Rough Terrain: Ride cautiously, look out for obstacles, keep feet on footboards, and avoid jumping.
    • Skidding/Sliding: Learn to safely control skidding at low speeds on smooth terrain. If rear wheels slide, steer in the direction of the slide. Avoid braking or accelerating until control is regained.

    Always wear an approved motorcycle helmet, eye protection, gloves, boots, and long-sleeved clothing. Never operate after consuming alcohol or drugs.
