So...this bike is "finished" but not on the road yet. I have very few miles on it, riding it (illegally) around the back roads near my house. It definitely needs some tuning down low. I can feel it surging or hunting at part throttle. Runs like a raped ape up top. It can be a little difficult to get cranked if I let it sit for a few weeks. Not having made it to the dyno yet, or even pulled a plug, those things hint to me at being lean on the bottom end. If I remember correctly, the mixture screws are on the engine side, so they meter fuel and not air. Think there's anything I can do with them to help? Or just wait for the dyno runs and see exactly what I need to do? The DynoJet kit didn't come with any pilot jets that I remember.

There's a guy parting out a 2001 Bandit 1200 near me. I'd like to use the smaller, neater oil cooler on my build. I have the 750 Teapot oil cooler and it's huge and the oil lines are routed oddly because they were hidden behind plastic. Now the bike is naked. He sent some measurements and it looks like it will fit my frame/mounts. Any harm in swapping them out? I asked him for the oil lines and hardware, too. Think that will all swap over to the 750 engine and clear the exhaust, etc.?

This is the best place I've found for this specific genera of OSS. There's the GSResources site, though they tend to focus more on the GS and the older models. But still some great Suzuki knowledge there. (Mods, I hope it's OK to post a link. https://www.thegsresources.com/_forum/forum.php )

I plan to be there! Make hotel reservations now. Event tickets go on sale in June.

Yes.... missed last year but plan on going this year. Mind blowing place/event.

I'm in South Carolina, about 20 miles south of Charlotte. Any of you ever make it to the Barber Vintage Festival?

But I dont have a matching connector for either of them.... yet. I may try removing the wires from the Teapot connector and then removing the connector from the B400 harness..... see if I can just push the pins in instead of splicing wires.

Edit: I have with wiring and the mount for the clutch safety switch. I found the missing switch itself, genuine Suzuki, for only $12.86 shipped, so I'll incorporate that. There's no mount on the GS550 frame for a side stand switch. I'll need to bypass it.

I studied the 750 harness today and the wiring colors all seem to match. I ordered a Bandit 400 wiring loom so I can use the correct male connector. I won't be using the side stand switch or clutch switch (this is all going in a GS550 frame). If I just use a jumper for those two switches, will the turn signal/side stand relay in the 750 harness still supply the correct power and ground to make the neutral light work?

A couple that I'm still trying to wrap my head around is why the Neutral light gets a Blue/Black (LB) from the side stand diode. Hafta figure out a source for that on the 750 harness.And what the Orange/Green is for (OG). It runs from the RH switch, turn signal relay, turn signal fuse, etc.... is it just a fused power source?

Ah, sir..... you are correct. I should have paid closer attention to the legend. Gr is indeed gray and not green.

On the B400 there is a GREEN coming from the ignition switch and the headlight switch. The only two colors going to the dash back lights are GREEN and BLACK/WHITE. The BW is battery negative (earth) , so the green is power..... keyed power, right? But the headlamp fuse goes to the ORANGE wire. And on the B400, the PASS (passing flasher for headlight) it also looks to go from a GR to an OR wire. Am.i correct in thinking I need to supply power to the GREEN on the B400 dash for power for bulbs? The 750 doesn't have an ON/OFF switch for the lights. On the 750, power is fed from a GREY wire and BW (earth).

That's the plan. Probably going to get a donor B400 harness just for the plug. And, yes, there will be "extras" on each end I won't need.

OK, that makes sense. And, on the 400 diagram, the BW (black/white) looks to be coming from the negative terminal of the battery, so it's an earth/ground? Now I need to study the GSX750 diagram and see where they were getting the tach signal. That would go to the BY, correct?
