Tachometer problems on Beta EVO

Hey all,

I've installed a Tachometer [Hardline Hour/Tach] onto my Beta but the RPM it's showing is way off. When I touch the wire in any mode (near the spark plug end) with my fingers it drops by a factor of x2. Am I missing something?

The tach supports the following modes:

* 1 pulse = 1 revolution
* 2 pulses = 1 revolution
* 1 pulse = 2 revolutions

RPM shown in the following mode:

* 1 pulse = 1 revolution (4000rpm)
* 2 pulses = 1 revolution (2000rpm) (drops to 1000 rpm, when wires are touched)
* 1 pulse = 2 revolutions (8000rpm)

Any ideas? #-o If you are currently using a tach/hour meter with great success what brand/mode?

Thanks!
