Engine

• The 2003 Yamaha Blaster has a two-stroke internal combustion engine. Two-stroke engines are capable of finishing process cycles by just one crankshaft revolution and one piston downward stroke. Four-stroke engines, which are common in ATVs, require twice the amount. These types of engines lack valves, which in turns reduces both their weight and construction. The engine of the 2003 Yamaha Blaster is air-cooled, which means that it depends on air circulation just above its hottest components to achieve proper cooling. The displacement of the engine refers to the full volume of its valves. For the 2003 Yamaha Blaster, the displacement is 195 cc (cubic centimeters). The compression ratio is 6.6:1.
  
  

Brakes

• The 2000 Yamaha Blaster's front brakes are dual drum brakes. The rear brakes are sealed disc brakes. Drum and disc brakes function on a similar notion, which is that shoes apply force over surfaces that are spinning. Disc and drum brakes generally consist of similar components (such as pistons and brake shoes), although drum brakes include extra features, including springs, emergency brakes and adjuster mechanisms.
  
  

Drive Train

• The 2000 Yamaha Blaster has a manual clutch, six-speed transmission. The manual clutch is responsible for both engaging and disengaging the ATV's engine power, which permits the vehicle to either start or stop.
  
  

Dimensions

• The 2000 Yamaha Blaster has a dry weight of 320 pounds, which does not include fuel or equipment weights. The overall height of the 2000 Yamaha Blaster is 41 inches, while the overall width and length is 41 inches and 69 inches respectively. The seat height is slightly over 29 inches. The wheelbase, which is slightly more than 43 inches, is the distance between the center of the wheels in the front and the rear.
