Honda Spree and Elite 50 Forums

can any of you wiring gurus out there help me with tach wiring, I have and old tach that I want to hook up, just not sure how to mate it to the cdi setup on my 84 spree, I'm sure some of you guys have done it.

First, not just any tach is gonna work. A car tach with 4-6-8 settings will not work, it will read anywhere from 1/2 to 1/4 of your actual engine rpm. You need a tach for a 2 stroke. Wiring the tach will depend on what kind of tach you have. A Tiny Tach has built in batteries and to connect you wrap the wire around the spark plug lead and ground the other lead (if it has one).

Hi - welcome back!
Like Bear says, there are a lot of ways to for a even a cycle tach to interface.
Here's some links to tachs showing a few different connections. Some have adaptors, inductive pickups, some tie into the coil wiring and some are just a wrap of wire around the ignition coil wire.

thanks guys those links will give me a really great start, i figured the 4 stroke tack would show 1/2 or 1/4 speed but if I can get it to work in that state that is all I really need for now, I just want a cool gadget that moves when i rev up. And down the road when i can pony up the cash for the right rig i will do that for sure. one of those links will have the answers i seek i'm sure. and whewn I have tach in hand i'll post somee pics. Here is one like the tiny tach but pretty cheap!

Hello all,
New to this forum looking for information on sun pro 2 tach mods. Found on a web search where mousewheels had made mods to these tachs. Would like to get in touch to discuss a project I’m working on.
