I tried to test the RPMs to see how accurate the tach gauge is on the RX, but with the coils in the sparkplug caps and sitting deep in the head I couldn’t get an electrical reading on a hand gauge. All the doos I’ve owned had rpm gauges reading 200 higher than reality. Has anyone ever test the rx-1 tach for accuracy? If its anything like the speedo, our clutching goals could be way off.
