Missed Connection

[The Buddha]

Did you have to swap the harness back ? Maybe the trigger, advancer in the new harness would have done it - or not.

Cool.

Yes sir, I did. The newer one has a plug for the updated igniter. Bike did start but didn't go, as in when the kickstand is down. However, the kickstand sensor is connected. What I'll do later, is to keep trying my luck and changing the neutral switch. The older has only one blue wire coming out of it, for which there's a plug to connect it to, but the newer has three wires going to two plugs; so, for now, there's one plug with two wires coming out of that switch, which isn't plugged to anything.

I must be very close, as the engine does start, and the carbs respond to the throttle.

Seems to be a mechanical issue with the clutch. On the center stand, the rear wheel turns on neutral and stops with first gear engaged. However, at that moment, pulling the clutch lever does nothing. Tightening the adjuster at the bottom had no effect. Gonna have to drain the oil and open the right side to check the springs, or the plates (probably the culprits).

thats some next level gear indicator, mine got only one wire to it, (top left to the sprocket), the other wiring goes to alternator. Cant find those color codes from wiring diagram, sorry.

Alternator runs 3x yellow wires which come from behind the front sprocket cover and run up under the seat and join another two wires before heading to the regulator/rectifier on the right hand side of the seat ... I can't remember where the 2 wires come from - possibly the RH crankcase.

Yes, '02s also have the 3 yellow wires you're mentioning. That's not the wiring I'm referring to; the ones I'm talking about come out of the same zone, but above where the clutch pushpin goes into. 02 models had just one blue wire going to one connector, and nothing more. 04s and after, had an extra pair of wires coming out of the same part, but going into their own plug, that the older wiring schemes didn't have.

Ended up being a very easy thing: The "clutch mechanism" needed to be adjusted a bit. I'll give it a ride tomorrow, but tonight it didn't die when I engaged a gear with the clutch pulled.
I'll live without a tach till I get me one (read somewhere that those things can be wired to a coil, and they'll work - I believe it was in a post by THE man in this forum that I read recently). I also need to figure out where to place the horn; I'll be silent on my ride tomorrow.

Closing it up by saying that I rode it around the block and worked; didn't die.
It's VERY clear that I need to adjust the throttle (methinks I need to tighten the return cable) and the clutch (still not exactly where it needs to be)
Also, have to solve the tach thing.
Not complex things, compared with the engine replacement as a whole.

Once again, the wealth of knowledge in this site seems bottomless. To think that after all these years I would find information posted by Adidasguy, that actually gave me a solution in a block I found, is beyond belief. Also, to get advice directly by Mr Buddha is something very special.

Thank you, all.

Reopening the post to ask how to wire an elec tach to the old bike. I tried to wire it to the right coil, but no combination worked. Hoping I get suggestions here.
(replaced the signal generation hardware and wiring with the old ones, and the bike starts and runs. The only thing that's off, is the elec tach)

[The Buddha]

You have 2 options if you ask me - Assuming you want to use the original gauge cluster - which I love BTW, would paint it black along with the triples but its never getting tossed - But a working tack is important - so.

First option is.
https://www.ebay.com/itm/LCD-Screen-Digital-Motorcycle-Speedometer-12000RPM-8-18V-Gear-Tachometer-Gauge/283514293544?hash=item4202c4cd28:g:5D8AAOSw-ZBdANCU

You can find out how to fit it in the pod, I have one of those but I only tried to fit it to a yamaha bolt which takes a jae-mx31 or some crap plug and cant be crossed over easily, but its got a plug into the wiring and it has all the warning lights which would leave the original in the gauge cluster useless - but it does look good by itself in the gauge and tells you what you need to know.
The speedo in it is digital and needs the cable, but the tach uses a wrap style pickup around the plug wire. It will work if they're not lying about that. The housing is metal, and almost the same size as the tach housing of the GS, but the bolt spacing may be different, you may have to drill it and install a rivetnut or something.
BTW that gauge uses a mathematic caliberation for gear position to work, if you were to run the speedo cable into it, you may get gear position to show. You can also wire it for head temp if I'm remembering correctly, and use the water temp guage to show ambient temp - cool gauge IMHO.

Option 2 is a dedicated tach only - Like this.
https://www.ebay.com/itm/Motorcycle-EFI-Tachometer-Tach-Gauge-For-Universal-Harley-Honda-Suzuki-Yamaha-CB/253295592642?hash=item3af99804c2:g:4YwAAOSwAHZUPpmY

Again measure that it will fit the housing and may need to mod stuff to fit it.

There may be other options - check and measure before buying.
I have another one that is about the size of a hockey puck, which means there is a lot of room under it to make it fit, but they seem to not be selling those now.

Cool.
Buddha.

Those two look very snappy, Buddha, and not overly expensive. They would be wired to what, a coil?

Also, is there any way that a newer GS tach can be wired to something in the old bikes that would make it work?
Thanks.

[The Buddha]

I never had a post 00 GS. No idea what a electronic tach on those gets its feed from, but there is a different advancer and different TCI and what not on those. Maybe it gets its rpm feed from the TCI.
These use some inductive sensing from the sparkplug wires. I only bought those, never wired em to my bolt, so no idea.
Bolt doesn't have the same 3X3 cheese cube molex plug, its got a jae mx35 plug for the dash. Was too much work to switch to a molex, so I have these tossed somewhere.

Cool.
Buddha.
