WGs wire mod on 80 kaw 750-4

I could use some tips on Wired Georges power tips. Anybody do it to an 80 750-4. Some directions are just not explained well, but most of it is because my wires are'nt where the directions say they are. Some hints from someone who has done it would be nice. Thanks :S

I haven't done it to an '80s 750/4, but I imagine it can't be much different from my '78 650/4.

The only existing wire your dealing with is the power supply to the 2 coils. On my 650, it's a red/yellow wire that has a dual (2 plug) connector that the 2 coils plug into.
Disconnect the 2 coils. Run a single wire from the dual connecter to the relay you've bought, to lug # 86.
Now from lug # 87, run a new wire back to the coils, splitting so each coil will get this power wire.

The new relay will get power from the starter relay connection, the one that is getting the red wire from the battery. Connected to lug # 36 (or #30 depending on the relay you bought) with a 10 amp fuse inline.

Lug #86 of the new relay needs to be grounded to either the frame or one of the ground wires of the bike, which are black/yellow in colour on my 650.

There you go.
Your 750/4 has an electronic ignition which will be getting power from a red wire and will still get power from this.

Dose this help. Ask away if you need more help.

Can you find the coils on your bike? There are two SMALL wires connected to the coils. One pair of wires will be a black and a green wire. Leave these alone. The other two SMALL wires connected to your coils are the power wires. They will be screws onto lugs on the coils OR plugged in. These wires will be pink or red or yellow/red. Use these wires to TRIGGER the relay. This is the ONLY wire on your bike you need to find and I don't know how to make it any cleared in the instructions.

The other wires are wires you ADD... a ground wire which is connected to either an engine bolt or a bolt on the frame. A battery connection which you will connect to the starter solenoid hot terminal also connected by the battery cable (big red thing). This battery connection will be fused (have a fuse in line). Last, there will be power OUT of the relay to the coils where the PINK, RED or YELLOW/RED wires had previously been connected to the coils either by screwing them to a lug OR via a connector.

I apologise, if I upset anyone on this forum, asking for clarification on a subject. I guess I was under the wrong assumption that this was the place to ask questions. It will not happen again. Thanks for the replys.

:blink: WTF?

Welcome to the site poolboy snd dont worry about offending anybody - which you did'nt. If you have questions ask away.

I did the coil mod on my 1980 750/4. First thing I did was take off the gas tank and trace the wires from the kill switch to where the red from the kill switch connected into the wiring harness to the reds going to the coils. I probably went to far but just wanted to be sure I had the right wire and I was able to tape it all up again when I was finished.
The red from the kill switch is the only one you need to cut.

See my post here whih has some schematics. If you see a blank picture box with a little red x try clicking the red x

I may even have photos somewhere. Shout if you need them.
Some general tips - I soldered all connections. I used electrical shrink wrap on all connections.
I found a point under the seat just forward of the battery on the left side where I could bolt the relay and pigtail

It was well worth the hour it took me.

Do I hear a hint of sarcasm?
Welcome to kzr poolboy. In my opinion , one of the problems with internet forums is things can come across the wrong way without the use of emoticons :ohmy: :woohoo: , it's hard to tell what a person really means.
With 11,000 plus members, it's really hard to tell a complete newbie from a kz guru so sometimes questions get answered with the very basics.
So please, keep the questions coming.
Chances are, because you asked the question you did, someone else got an answer they needed.

Tony, JR, wiredgeorge, rstnick,
"Some directions are just not explained well". I should have said, "Some directions are not explained well enough for me." because I'm not a mechanic.
I think I ticked off wiredgeorge a little with that statement. Thats the reason for the "hint of sarcasm" on my part.
Wiredgeorge is a pro at this stuff, so are all of you guys, but if you put a period where you should have put a comma, it can change the explanation enough to confuse some folks like me whose eyes go very large when I take off the tape on a harness and see all those wires running every which way. :huh: I don't trust myself with an ohm-meter, so I tend to unwrap a bunch of wires to see where they go. I draw a schematic of where the wires go, so that I know whats going to happen when I connect the battery and turn on the switch. What originally threw me off was this.
"Relay Trigger # 86
Find the yellow/red wire that had been previously been used to power the coils." First off, I thought a yellow/red is a yellow wire with a red stripe, and I could not find it. "This wire terminates in a dual outlet female connector." I was looking for a connector over the valve cover. It was'nt there.
I was simply asking for some clarification, which I now have, thats all, not to incite anyone. :blush: My humble apology's

So how did your coil mod turn out?

JR provided a link to a drawing of the mod he did on his bike. Its becoming clear to me how to do the modification without messing it up. With a little apprehension I will do this when the rain stops.
Thanks, sometimes, is not enough. And Thanks Tony for your help.

Right on
Once you get stuck into it, it will become even clearer. I'm a rank amatuer like most of us here and I managed to figure it out so you wont have any problem once you get going.
Cheers

I wasn't ticked off. I answer a lot of posts and type fast so I tend to be matter-of-fact and rather humorless. I have a Vintage Bike Tech forum linked off my website where I answer quite a few questions as well. You have no idea how many times a month I get asked about the coil repowering mod... it could always be written up better if you or anyone else wants to take it on. I would be happy to post the write up on my site.
