 Negative is on the end, the positive is towards the middle, both labeled on the unit and the wire color.
 
  Removing the baffles/homemade velocity stacks inside the pods improved the WOT air fuel ratio. At over 85mph (max speed readable) and the throttle wide open the a/f ratio stays no fatter than the mid 10's.  I can say for sure the seat needs a bigger hump to keep my ass from sliding back. It's also hard to look at the gauge while doing that, a camera recording it is a great idea.
  It still has an occasional exhaust pop and mid throttle burble, that has me concerned, when I get time, I may do a leakdown test. The usual methods don't show a vacuum leak.

Yes ! 

Don,you completely went through the carbs ?

[Don R]

 No, I haven't rebuilt the choke plungers, and I only cleaned the jets and passages and verified they were open with carb spray but without total disassembly.

I think a nice set of bigger carbs will certainly benefit that bike Don ! 

[Don R]

 You're probably correct, I met a guy at Advance auto yesterday that owned some GS1100's back in the day, he ran the 29 and 33 smoothbore carbs. He preferred the 29's but because he was willing to give up top end and wasn't getting the 33's jetted right. I believe his bike was less stock than mine.
 I may still have one carb acting up the exhaust probe is getting is a mix of all 4 cylinders.
 I've been working on the race car and tow rig this week. When I get this work done I want to move the trailer over and back so the 40 chevy can come out of storage. I made some repairs last fall and want to see how it goes on the highway. I have a lifetime collection of toys that all need maintained.

I like the sound of many choices/collection.

We put 170 air jets in the stock carbs on the 81' with K&N pods and cured the mid-range stumble.

[Don R]

 The part throttle thing is a cruise rpm miss more than a stumble. I really have a lot to learn, I was surprised to see difference of 10-1 to 12-1 in the 5th gear, 70 mph AFR when the wind direction was reversed. This was with the pod restrictors that are now gone.

  I was thinking about why my helmet is suddenly lifting so bad, then I realized it's the 85 mph speedometer. No idea how fast I was going, except over 85. I didn't check the tachometer. It was all I wanted to do to glance at the AFR meter for the WOT check.
  APE pod filters were ordered online, I hope they get along OK after Big Jay's passing, I'm sure the employees and family need the business to continue as well as possible.

[Don R]

 I mounted the Polaris type V-Reg. The excess temporary wiring is for the AFR gauge. Revved up a little it charges at 14.5 volts.

Hoping it'll get enough cooling ventilation.

I put mine in a similar location, layed vertical under lh side top frame rail.  It has given no problems.

[Don R]

 I lowered it to make an air gap under the seat, I'm also hoping it will cool enough. I'll give it a workout with the AFR gauge working and high beam then check it for heat. The replacement stocker is still in place just in case of whatever.

As long as it gets airflow 

[Don R]

 I think the lack of an airbox makes an airflow difference. When I get the APE pods on it, I'll re-check the AFR and see if I can duplicate the difference in air/fuel when the wind direction changes.

[seanbarney41]

Yeah, I notice a little on a really windy day.  Every once in a while go to grab a handful during a just right gust and it will just go whifff for a second...but really, my gs1100 with pods is about 110 percent better overall fueiing than any of my other bikes stock, pods, etc.

[Don R]

 Yup, going one way 12.5-1 or so, coming back, same speed same road, same wind, it was around 14.2-1.

 I may construct a set of shields to cover the filter area from the side just to see if it's side wind doing it or head wind differences.

I'm trying to get my nephew's to 3D print a storage box that hangs from the frame rails. It will fill the space the airbox used to fill. A useful addition and I will see if it helps with the pods issue. Problem is they are too busy with robotics right now.
It's not a problem on the 80' GS 1100E with the RS36 carbs that I can tell.

[Don R]

 When I made the V-Reg bracket I thought it should be a drop in tray that can lift out or hinge up. It would be nice to carry a tool kit. The tail fairing also could have been made to hold something like the Honda Super Sport does.
 I noticed the LED taillight bulb messes with the warning panel, it thinks the bulbs are burned out.

[Kelly E]

Originally the tool kit bag was stored in the tail. There's supposed to be a rubber strap to secure it. I want my nephew's to also 3D print a storage box for the KZ 1000 too since it's also running pods and RS34 carbs.

[seanbarney41]

Yep, my '82 has storage (Not much) in the tail section

[Don R]

 I better look again. L0L!

[grcamna2]

I better look again. L0L!

The rubber toolkit hold-down band/strap is still available.  pt.# 09462-00072

The 78-81 CX500 and CX500 Deluxe versions had a plastic blow mold toolbox older that fit in the tail cowling in front of the headlights. It disappears on many bikes that have had many owners or went through a re-paint... the rear of the seat covers the opening. FWIW...
I looked for a while as a PO sold or removed it...the PO did some shoddy work, teenager who basically assumed title on an abandoned bike by a teacher that lived in Delaware on the island and this kid and his dad ended up with it. It was unclear from the listing he still considered it a project so I wonder if he ever got it legal and rode it or if it was always a project. It ran fine but had some issues that I had to address before titling it in AZ after the shipper got it to AZ. The photos were too kind as the paint on the frame was truly a botch job and I am going to have to strip the frame and repaint it...looks like it was brushed and tried smoothing it after it began drying as there were clearly brusharks to go with the areas where he stripped paint likely some corrosion issues I am guessing from being in a coastal Atlantic island and thought he could just paint those areas he stripped to bare metal....total botch job.
Hope you get it sorted...

 I rode to the industrial area where my 40 Chevy was in storage today, once there I could see open street with no driveways for several blocks and let the gs loose a little. Holy crap, the sound of that Kerker was incredible, it was the first time I could hear it echo off of a building. 
 The metering rod needs to drop at least one step and maybe another main jet size. No word from APE on my air filter order. I'll give them some time, they have only been open a week since the loss of big Jay.

[Don R]

 I rode the Rat Race 836 with 29's but without air filters to the storage unit and removed the air filters from the Suzuki, I put on the Honda's velocity stacks for an air/fuel ratio test. Oh my, it went instantly lean and ran extremely lean all the way home. I was going to go back for the air filters but there was need for a restroom that doesn't exist at the storage unit, so I hobbled it home.
 I called APE and got a set of their filters ordered, of course they checked when I asked, and don't have them. The TSR said a week tops so I decided to wait. Jegs sat on my money for a month so what the hell?
 Part 2, I ate a sandwich, went back out and it ran fine. The air fuel ratios appear a little leaner than with the filters on. I have a largish inline fuel filter on it that appeared empty when I stopped to check things, now it has gas in it, either it gelled up or the new K&L petcock acted up. It almost takes pliers to move the lever on that petcock, not a big issue because I rarely ever need to move it. 
  This unexplained #$%* really gets my goat. I feel like I need to figure these things out to avoid it again in the future.
