The Yamaha Blaster is a 200cc air-cooled single cylinder two-stroke all-terrain vehicle produced as an entry-level machine manufactured in Japan and sold in the United States from 1988 to 2006. Because of the Blaster’s initial low price tag, it sold in large numbers for many years. Its two stroke engine is easily modified by enthusiasts and a large aftermarket now exists for the quad. A wide range of add-ons are readily available from simple bolt on exhausts and suspension parts to complete aftermarket frames and larger displacement engines.
The heavily finned, air-cooled Blaster engine has roots from a water cooled machine, as evidenced by the plugged water pump casting on the right side of the engine. The history of the engine in its water cooled form can be traced back to the Canadian market Dt200 and the Australian market WR200. Theoretically, it would be possible to use parts from either of these bikes and build an all-Yamaha water cooled Blaster engine, or to simply swap the engines since the engine mounts are nearly identical.
