Tach Questions

[kantornado]

1st things 1st I was not prepared 4 how many 2 inch tach's were under $50. Most are between 10 and 25 $.

 

2nd with so many choices between electronic/mechanical/digital/L.E.D. what is best and is the more wires it has better 1 has 7 wires out the back to several locations or do we (K.I.S.S) (keep-it-simple-stupid) with 1 wire to the spark plug??

 

3rd Color choices on the face with so many 2 choose from it's real hard to figure out because of sun light and mounting location. There's blue,red,yellow,white with color graduations to the red line, black face with color spectrum's off the charts (very pretty but practical??) Then just numbers and red line is another color of light depending on choice of digital read out and face color.

 

4th I am mounting it next to the cruise switch under where cassette door used to be.

 

5th Why does everyone seem to buy Barons or H-D ones with all these choices. Is it mounting options??

 

 

I'm not a tach guy never mounted one in a vehical. Just used them for work.Thank you in advance..............Ron

One of the things you might want to check on any tach you decide on, is whether it's compatable with a wasted spark ignition.... The RSV are wasted spark systems. The Autometer Pro-Cycle tach I put on the '99 had 4 dip switches and would handle 1 or 2 or half pulse signal.

Like me a lot of people buy HD compatible tach and they install just fine. 2 wires!

Thank you CONDOR and BUBBER I will check on wasted spark ignition. I did not know this about the RSMV. There are allot of tach's out there that are 4-6-8 cylinder rated & are for motorcycles. I just need to find out about this wasted spark thing. So its off to research............Ron

Waste spark ignition systems fire the plug on the exhaust stroke as well as the compression stroke. Some tachs need to be set to two cycle to account for the extra spark.
