do a carb swap and get rid of all the electronics except for an ignition source. :mrgreen:
It has dual carbs. If I understand you correctly though, then what BobManifold is saying about keeping “7 wires” is accurate. Cap off all the vacuum lines and ditch a bunch of sensors and electronics. Change the jets in the carbs for a larger set and then go for a ride.

You're in way deeper than I can go. It's all I can do to troubleshoot and maintain my '91 GL1500 and put it all back together again!

:lol: Well I hope it helps you if you ever decide to slim down some features. I was trying to build a wire map that would make sense and I can upload screenshots or post a document library with what I have made so far. I am thinking that some of the sensors and systems on there help it run smooth with all the original hardware but since I am cleaning all of that off the bike and really just keeping the frame and motor I really only need the “essentials”. I think I will take what I have and make a separate tab that breaks out the “essentials” so you can see the whole system and see the minimum in case someone that knows enough to be dangerous wants to try and build a middle ground, like what Pedro is doing.

if it isn't injected than you don't need the o2 sensor, throttle position sensor,etc,etc,etc. If they even have that. None of my bikes are young enough to drink from an injector. :-D

Did some poking around and the only thing I am trying to sort out now is the pulse generators. Seems like the ECU has some magic to make sure it fires the in an order.

The pulse generators tie into the (TA) and (TW) sensors and to pins 5,7, & 8 on the ECM. Maybe the ECM is using this as a ground or those to do math and determine when to activate the ignition coils? :dunno:

Good evening all,

I took some more stuff off yesterday, the front subframe that guides the speedo cable and holds the air temp sensor. It also is where the radiator screen is mounted so I need to fabricate a location to hang that now. I ordered some parts to get me started on my rewire, front turn indicators, rear lights (in the form of an LED strip), left side control replacement (still need to replace choke control though), a new starter relay and a motogadget m.unit to replace OEM relay/fuse boxes. I am probably still missing something. :dunno:

Anyways, I have been drawing out what I think is going to work for accessories, but I haven't figured out what pin is pushing power to the ignition module(ECU).

You might want to take a look at a 1500 Valkyrie wiring diagram. Same engine, just without all the additional gizmo electronics. Also carbureted, but with 6 instead of two. It may be a blueprint of what you need.

Thanks, I have been staring at these a lot this weekend, well this last almost year actually. I have the Honda service manual for my bike so I cross reference it since it’s not colored. anim-cheers1

I can PM you a color schematic for the Valk if you need it.

Let’s give that a go, it might unlock something I’m missing.

I am pretty confident I am missing some technical knowledge. I should lean more into my service manual at this point.

PM sent. Let me know if you didn't get it. I can't quite figure out what the difference is between the "out" and "sent" directories are in PMs.

I got it, thank you. It looks like it takes a bit for a PM to get picked up from the "outbox" but once it is picked up it is then officially "sent".

A PM sits in the out box until the person you sent it to opens it. It may sit there a day or less or a week or much longer. But it sits until they open it. That way you know when they read it. This question comes up about every other month or so. ;)
