Re: Add a Tachometer

Anyone know of a good place to get a single fire tach that is not to expensive. It seems all the ones I find it doesn't say or if it does they cost $200+.

Re: Add a Tachometer

Read the first post on this thread. Where to buy and how to install. I have one, it works great.

Re: Add a Tachometer

Here is one on eBay for the single cylinder Savage 650. This one should do the trick. No problemo.

It looks exactly like the one I put on my GeeZer. It's $69.99 Tachometer

I'm pretty sure the GZ fires on every stroke, not just the power stroke, and that is called double fire.

A single fire tach only expects to see a spark on the power stroke and would read 2X the actual RPM.

So why would ANYTHING want to fire on the exhaust stroke? Just seems pretty pointless on the designer's part, designing something more complicated with no use whatsoever!

:plus1: Yes, The G.Z. fires on every stroke, Duel fire ignition.I think it has to with the design of the ignition module.

So what you're saying, right, is that the designers can't design shit? I don't think I'd admit to designing anything so totally useless. :??:

Surely, if you're being paid to design an ignition module, you'd design one that fired only on the ignition stroke, which is the only place it's needed. O_o

Yes but it is cheaper, simpler and more reliable (fewer parts) if you just let it "sync" with the piston and fire every time it approaches TDC. :cool:

Having a spark at TDC on the exhaust stroke really doesn't DO anything useful.......but it can cause some interesting back-fires if the mixture gets really rich or the valve timing gets out of whack.
