Types of Gauges for Homemade Go-Karts

Gauges provide a vital link between engine and speed conditions, and the go-kart's operator. The operator quickly learns the normal operating range of each of his gauges. If the gauge indicates a reading outside of this normal range, the operator knows that there is a condition that needs to be addressed. Because a gauge offers this real-time information, it can help prolong the life of the engine, as well as play a vital role in preventative maintenance of the go-kart.

  1. Speedometer

    • A speedometer attaches to the transmission, or the axle of the go-kart. It gives an indication of the speed the go-kart is traveling. Many are mounted to the top of the steering column. This mimics their position in an automobile and makes them easy to read while driving. Many of the speedometers that are found in go-karts have been adapted from motorcycles.

    Tachometer

    • If the go-kart is used for racing, a tachometer is considered vital. The tachometer gives a reading of the engine speed. Knowing the engine speed is especially important in a manual transmission-equipped go-kart. In order to achieve top performance the operator shifts the transmission at predetermined engine speeds, called "shift points." The tachometer indicates when these shift points are reached. Many tachometers have a "rev limiter." This allows the operator to set the maximum rpm that the engine can reach. Limiting the maximum rpm protects the engine from internal damage.

    Oil Pressure Gauge

    • An oil pressure gauge indicates the amount of oil pressure that is required to keep the oil in motion. Oil pressure gauges help you keep tabs on the engine's crankcase. If oil pressure suddenly drops, or rises, the operator sees this and can stop the engine. Crankcase damage --- such as spun bearings --- is expensive to repair. Having the ability to spot a failure, as it happens, will go a long way in preventing engine damage.

    Water Temperature Gauge

    • Many homemade go-karts are water cooled. A water-cooled engine must maintain a certain temperature range , if damage is to be avoided. A water temperature gauge monitors this temperature. A water temperature gauge alerts you of any abnormalities that move the engine away from its optimal temperature range. Damaged hoses, bad water pumps and stuck thermostats will all create conditions that will be indicated by the water temperature gauge.
