Thanks Motor Head, I wasn't sure that was possible, great!

Oh yeah, I forgot, I could spend some time trying to figure out how to connect my brand new Acewell multi-gauge-thing - should be exiting!

I bought this bike last July and a year later, after much work of a complete tear down and rebuild, I am hoping to be done soon.

This site has been crucial to this build, so thanks to everybody so far for all the help and great advice.

I only have my SS brake lines, rearsets, and headlight to order. I have a friend working with me on rearset mounting brackets.

I need to install my Vance and Hines 4 into 1, my Acewell digital gauge, kickstand, rebuild the petcock, finish fuel lines/filter, add oil/filter, install front LED turn signals, and paint the tank and side covers.

Here is pic of the bike as bought for $400 last July. Ran, leaky carb, and leaking oil in couple of spots. Looking at the registration card under seat, PO last road bike (legally?) in April 1998. From the rust in the gas tank, probably did sit for quite awhile in the barn I picked it up from:

When I got her home and out of the truck:



A couple of pics of the filth I was working with. Not sure if this bike was ever really cleaned:







I have been posting pics with all of my questions as the rebuild progressed, but here are some of the latest pics:







I will post some more as I go along. Thanks again guys for all your help so far.

Did you read this?

So here is from the 2856 Page, www.acewell.co.uk/Acewell%20Speedometers...tm?action=full&id=18

Yes i am using 1 of those instead of the cable drive, i ordered it as an extra.

From their website

Q: I'm using a cable drive converter, how do I calibrate the speedo.
A: Before fitting the acewell, it is necessary to find how far the vehicle moves with a single turn of the speedo cable.
Mark the tyre and ground, and push forward 1 wheel revolution - measure the distance travelled in MM.
Put a piece of tape on the end of the original speedo cable to produce a flag, push the bike forward 1 wheel revolution again, but this time count the number of revolutions of the speedo cable.
Divide the distance travelled, by the number of rotations of the speedo cable, and enter this number into the acewell.
e.g. If the bike moves forward 1700mm and the speedo cable turned 3 times, then enter 567 into the C screen

I had to download and Install some Chinese Font stuff to display properly.
So you have a sensor that goes directly into the factory Hub speedo cable fixture? If so I would get the front wheel up off the floor, and remove the sensor. Then mark the tire, and place a piece of the old cable, if you have it, or another piece of something that will wedge into the square drive. Maybe put a small 90 degree attachment on the end of it to see better. Rotate the wheel and count the turns the cable end has gone.

We're using MH & its an Acewell gauge, model no 2856 from the attached brochure. Im using the gear at the hub but with a supplied sensor cable with the gauge it makes an electronic pulse with each revolution of the speedo cable drive, if i disconnect at the hub i cant see in to count the revolutions & i have no mechanical cable to plug into the gaugh, my original mechanical cable was no good & was dumped ages ago or i'd connect it to the hum & find out for myself

Looks great!

Thanks for the wiring photo for the Acewell!

Appreciate it.

Hey guys.

With the new Acewell gauge, I am not going to need the mechanical tach cable any more:


So what do I do with the tach gear connection on the front of the engine?

Is there a way to plug the connector without having to use the old tach cable?

Thanks.

Connections are as follows. The Black plug is what led up to the old gauges cluster. If you need further clarification let me know. This is for a '78 KZ650B so you may have some differences.

Acewell -> Bike

BLUE PLUG
Grey -> Blue w\ Red Stripe
White -> Grey
Light Green -> Red w\ Black Stripe
Light Blue -> Green w\ White Stripe
Purple -> Green w\ Red Stripe
Orange -> Green

WHITE PLUG
Black -> Black w\ Yellow Stripe
Brown -> Constant 12v Source (Battery)
Red -> Brown
Blue -> Not used (Fuel Gauge not on my bike.)

In other news I got my triple trees back from Leon (531blackbanshee), and new tapered bearings from AllBalls, Nissin radial master cylinder, and a ZX-6R clutch lever assembly. Absolutely amazing work by Leon, I would recommend him for anyone doing the swap. THANKS!!!

Still have some tidying up to do, but she should be ready to go this weekend!!!

I bought an Acewell gauge, the same one you have wired to yours.

You said it was easy to wire to your bike, but I am a little confused on the wiring...

Looking at the wiring guide Acewell sent, they have a pretty simple setup:

www.acewell.co.uk/manuals/ACE-2853-A-Wiring.pdf

But where they have one wire for a turn signal indicator, for example, my bike's wiring diagram shows 2 wires for each turn signal indicator. What's up with that?

I also am not completely sure which wires from my bike I need to use to hook up to the gauge's ground, clock power, switch key, fuel, etc., again, cuz a lot of those wires on my diagram show 2 wires leading to the hookup.

Any help would be greatly appreciated.

Thanks!

Try to grab a diagram with color if you already haven't. You'll notice on every diagram however, one of the wires from each light is tied to all the rest. With the Acewell gauge this all goes away because it shares a common ground within the gauge. I'm working on my fork swap at the moment, but I'll post a bunch of pics later and include the gauge wiring.
