The Yamaha Blaster is a high-performance off-road vehicle that was manufactured between 1988 and 2006. It features an air-cooled 195cc two-stroke engine, six-speed manual transmission and reverse start. This model was designed to be very light and fast, making it ideal for racing or other high-speed maneuvers. While operating in severe conditions, it may be necessary to adjust the engine idle speed to ensure smooth performance. As a result, the engine will perform better and reduce wear on other critical parts.
Set the parking brake on the ATV and start the engine. Allow it to fully warm up to the point where the engine idles on its own without assistance from the throttle.
Locate the mixture control screw while the engine is still idling. This little brass screw is located on the left side of the carburetor, right next to the choke lever.
Turn the screw with the flat head screwdriver. When the screw is turned clockwise, the engine rpm increases. When turning counterclockwise, the rpm’s will drop and eventually restrict all fuel from entering the engine.
Setting engine rpm higher than factory recommended can be dangerous for both the ATV and the operator.
