Ok, so after looking all over I found this Glowshift Digital Tach/Shift light combo unit that was small and I really liked it:
It was like $54 shipped, had the mount curved to fit the speedo bucket, and i think looked sharp. After searching around on the forum, it looked like Rawarrior also found this tach but ended up going a different route. So, here it is mocked up on my speedo bucket:
And the view from the drivers seat:
I like it! Of course I would clock it so that it the display is shown correctly. I would have to drill and tap new screw holes but that is not a big deal. The other benefit of this tach is that I can open it up really easily and waterproof the board and weatherproof the enclosure.
So, the first problem is I hook it up to the stock tach wire it reads exactly half of what my big autometer is showing. I almost expected this... since the tach only has options for 4-6-8 cylinder use. But armed with a bunch of info from this site, Vmaxoutlaw and http://www.gadgetjq.com/tach_install.htm I figured this obstacle was surmountable. So, I soldered up the simple diode/resistor circuit to take the spark off of two coils instead of one to give the tach the signal it needs (this pic courtesy of gadgetjq, but mine was identical):
I get it jumpered up to both rear coils (my bike is a 92) on the bike, fire it up and the tach reads 0. I pull off the connection to one coil and it goes back to reading half. So, I take the resistors out of the circuit, because some people just say you only need the diode, the resistor would probably only smooth out the tach operation. Still doesn't work...
So, I talk with Glowshift and of course they say that in a multi-coil operation, I need a tach adapter as it says in their product data. Well, I assumed what I built was an adapter...? They say I need an Autometer 9117 adapter like this:
Well, that thing cost like $70, and if I wanted to spend $130 on my tach I would have just bought the autometer tach/shift light like the Glowshift one. But I like the Glowshift better because it is smaller. So my question is, what is different between the autometer adapter and the one I built, or one of these:

I may just have to send it back, but I was really hoping this would work. Anyone have any ideas?
