Hello,
I'm looking to see about getting a tach set up, wondering about the wiring, where to tap into.
I dont have a tach yet, wondering also what you guys run that works well.
I have the wiring diagram from the book, I'm not running head/tail light or a/c rectifier. Just enough wires to drag it.
Tether cord and coil/engine wires.

Pics would be great to. Thanks TB

most tachs have 4 wires
one for ground usually a black wire, a power wire usually red, a blue for light and a green for the coil negative wire,
real basic to hook up,when you get one , post a pic or wire colors and ill walk you through the hook up

Sweet. My boss raced back in the late 80-90's , well his son, I asked him the other day what he ran for a tach...... sure as shit he opens his desk draw and pulls out the effing tach. Gooooo figure, he was unwilling to sell.

I've wondered about this also!

You might think about looking up Digitron they have egt,tach,and temp all battery operated usually used for gokarts, and indy car can get rather pricey some units are couple hundred

I use a digitron egt/tach. Great tuning tool and lazy way to jet

I run a Trail Tech on my XC bike. It has a tack, just one wire that wraps around the igintion wire. IMHO a tack is a waste on a R. It revs so quick and you have to take your eyes off the road to see where its at. A good ear is the best thing.

I had a digatron set up on my sphynx drag bike. Only kept it for a few months before parting it out but I had the EGT, tach, and temp on mine. I used it to tune the alky and it worked great.

Burns350,
I understand what you mean by, "tune" / "shift" by ear. I found that out when jetting down from 172-170-165 to finally 160, it had a different tone and "pull" .

Yeah a tach could only be good for drag racing if u in woods and look at the tach the next thing u will see s a tree haha

 

[TrailBurner]

I drag.

I run digatron. They have fantastic refresh rates compared to most tachs. I have tach and head temp on mine. Although you should be able to tune by ear I have still been able to fine tune to a higher degree with my digatron. Espacially with such a fast refresh you can see ur exact rev out

 

[TrailBurner]

I'll look them up. Thanks
