Anyone looking for a tach?

I bought a Tiny Tach ( http://www.tinytach.com/tinytach.php ) and it works
great. It has a lithium battery inside so all you have are 2 wires to connect,
one wire wraps around the spark plug wire and one goes to a engine ground
(I grounded mine to the valve timing cover). Now all I have to do is figure
out were I want to mount it.

The trailtech TTOs are pretty good too:

I've used them on moped builds. Usable resolution and long battery life. Considering using one of the water temp versions on my Yager when the warranty runs out. Want a bit more engine health info when making those max-speed interstate runs.

The one I plan to put on my 4T is this one:

Spendy, but I'm a sucker for an analog-style sweep.

That analog one sure does look nice. Like you said a little pricey but probably well worth it, I'd like to see where your going to mount it.

Will that analog sweep work on a 2t?

Jim, the Koso will work on 2-stroke or 4-stroke motors.

There's also this one, which should be fine for a 2T Vespa/Stella (don't know too many that spin past 8K willingly)...

And they have a cheaper, higher-revving option:

I dig the VDO, though. It looks more appropriate on a vintage 2T.

Which one is the VDO?
I don't see any one that has the VDO marking. .
Thanks...

It's the "Puch Monza" 8K tach. The Puchs were 2-strokes, so it'd work fine on a vintage Vespa.
