My 94 D1 has a tempermental tach. It will jump around for no reason that I can think of. It happens most of the time after the engine has reached operating temp. I checked the gap at what I believe is the sensor in the lower section of the distributor, and it is about the same whether hot or cold. I thought that it might have been electrical (voltage) related after I had to replace the battery, but it came back shortly after. Could it be gapping due to temperature differences? Thanks in advance! And I still love this "Beast"!

Might check your alternator -- tachometer failure often indicates an alternator on the fritz.

A friend's tach began not working right, turned out that the serpentine belt was mis-routed, which prevented the alternator from working properly... the routing made it so that the belt didn't grab the pulley on the alt enough, so it slipped, and was only giving a partial output.

A quick, easy, free thing to check....

Had the serpentine mis routed on mine as well. Stuck in MD for 2 days b/c of it. Took about 15 seconds to fix.
