Zongshen RX3: Engine Cooling System

The smaller the engine the greater the effect when the fans kick in / out or when the thermostat opens / closes. A 250cc engine doesn't make all that much heat so external forces will influence it very quickly.

Combine that with an imprecise digital gauge (only 5 bars to indicate the relative heat) and it may look like its bouncing around at certain times. Imagine if a heat value of 1 = 1 bar on the display & 5 = 5 bars heat, if the value is fluctuating between 2.999 and 3.001 the display will be bouncing between 2 and 3 bars even though the change in heat would be unnoticeable with an old school analog gauge. This is a common problem with digital displays.
