The Suzuki RM 250 was introduced in the mid-1970's and came equipped with a fuel tank capacity of 2.1 U.S gallons. Aftermarket fuel tanks are available which can increase that capacity if one still owns one of those models.
To turn on the fuel on a Suzuki 250, locate the fuel petcock, usually situated near the fuel tank. Switch the petcock to the "ON" position if it has an "OFF" and "RESERVE" setting. If your model has a vacuum-operated petcock, ensure that the engine is running or that the bike is set to "PRIME" to allow fuel flow. Always check for leaks before starting the engine.
