FYI, on these bikes clutch baskets benefit greatly from welding the rivets from the back, and adding small tabs to the gear as a  safety measure if you are to continue the 20 footers :) (or convert to a straight cut gear basket and do the above mods..... more money) Also add the 750 oil pump gears for much improved oil pressure and flow.

Cheap, and very effective mods.

Clutch basket welding and oil pump gears are a good idea.
Straight cut conversion involves a lot more than just replacing the clutch basket but I'm sure you are familiar with this stuff ;)

Not to hi-jack a thread, but here's a picture of my '82 GS for comparison ;)
I decided 19 years ago I need to get one of these bikes... what can I say, I really like them  ;D

Installed the painted front fender today and cleaned her up for the insurance photos.
I'll post a video the next nice day, but for now I'm very proud of the final outcome .

Come on Terry, it turned out pretty good for $1500.00 total + case of beer for painted fender ;)

mikunicarbs

Trying to richen up the fuel mixture, before I figure a way to hang some gas and do the carb balance, but trying to get close 
The adjustment screw is on the top of each carb on the manifold side. 

From what I have read, screw out is richer? But I also read where if it needs to be more than 2 turns out I need to re-jet?
I'm out 2 and my pipes are def to hot?

I'm a bit lost on this one.......any help is always appreciated :)

Tonight after my last post, I did get rid of a sputtering, backfire I had when I noticed one of the air filter side carb clamps I installed was not on the correct ridge when tightened down.

 I also opened the adjuster screws out 2 1/2 on all 4 and took a ride to the village and it was smooth without any misses or backfires at any throttle.  Looking better, but I would like an answer to my above question if anyone wants to jump in here;)

Still need to get the correct mixture with a sync I guess. Man are those new pipes blue!

The Suzuki turned out fantastic!  I need to find a painter in Denver who works for beer!

Sounds like you're getting it dialed in, too.  Nice job!

G'Day Derek, your Suzy is looking very nice mate, well done! Re: your carbs, I'm presuming that your airbox is installed with a new air filter, and everything is as it left the Suzuki showroom floor, yeah? As I've said previously, Mikuni CV carbs are much more sensitive to adjustment than our Keihin carbs.

Take your tank off and (installing longer fuel and vacuum hoses or using a dummy tank and plugging the vacuum hose connection between carb #1 and #2) run the engine at idle. Your mixture adjustment numbers are "ball park" at best, so with the engine idling (and if it's warm, with a fan blowing over the engine) in a well ventilated area, while watching your tach, slowly adjust your mixture screws in or out until you see the idle increasing, then keep adjusting them until you get a nice stable idle.

Unlike the idle circuits on Honda carbs, Mikuni CV's idle adjustment affects the bike's preformance regardless of throttle position, so if it idles like crap, it'll run like crap right across the rev range. Also, noting how blued your header pipes are, check your ignition timing, and don't assume that the ignition itself is not at fault, the igniter boxes in early GS bikes are known to work sporadically with age. I think they still offer alternatives to the OEM igniter box on The GS Resources website. How's your charging system? If your alternator isn't putting out at least 12 volts, your bike will run like shiite. Also, new plugs and caps are critical on these old bikes. Once again, well done mate, your bike looks great.  ;)
I was feeling sorry for myself because I couldn't afford new bike boots, until I met a man with no legs.

So I said, "Hey mate, you haven't got any bike boots you don't need, do you?"

Thanks. I'll re-read all this again tomorrow.
 I'll take a video of it running tomorrow. I know I need to do the sync. Now that the pipes are already blue and I think I may have it sorted with a nice idle and smooth running it's hard to know if I have it right now. ???

More learning to do on my end for sure.

The blued pipes are 1 and 3 which probably excludes ignition as a probable cause.

Mucked around with my new carb sync tool today. Tried to follow all the directions but the manuals all refer to a ball in a tube type.

I think I'll check the valve adjustment next as I am still getting a popping out of 1-2?
2-3 are supposed to be a bit less vacuum than  1 - 4 at least from what I gathered.

Any obvious brilliant revelations seen?

Revelation: your carbs need synching  ;) Have you adjusted them any yet?

I like the sync tool. Where did you get it? I have an old mercury tube type that probably doesn't have any/much mercury and yours looks like it's easier to use.

Yeah, I can move the pressure pretty much up and down at will, the key is going to be at what measurement are they right to set?

Get them all equal first. Thats the main thing. Did you see the carb sync instructions on the main page? Same gauges I believe. Some carb sets have 1 carb that you set all the others to. It is not adjustable.

Where did you get the gauges? I hope they don't disappear too  ;)

Have you got a workshop manual for it Derek? If not I've got one in my garage I can check for you? Cheers, Terry. ;D

You know I do. ;)
The gauges on mine are in lbs which for a Honda is fine as the manual gives the correct answer in lbs.
Suzuki is in cmHg so I'm not sure where on the gauge is the right setting. I have been using this tutorial, if you look at it you will see the gauge they recommend. http://members.dslextreme.com/users/cbsaunders/gs/carb-balance.pdf  I'm sure I'll do better my next time at it.

So I have taken a couple more runs at this since my last post.
I get that #3 is the one to work from then syc #2 then #1 then #4.

I was able today to get #2 equal to #3 and said hey, I might just have this figured out.

But it seems no matter what I do #1 and #4 just won't follow suit ::)

As this is my 1st attempt at syncing carbs, I really don't feel bad I can't get it, but it is frustrating.
I shut it off today because #1 and #4 were getting very hot!

WTF am I missing?

3rd and 4th attempts today ;)
Pipes all seem to be similar in temperature using a heat gun tester and all 4 pressures equal.

Still hear some surging though?
3rd.

4th

Sounds like the idle is a bit high, maybe a few hundred rpm.  Much smother sounding than the first video.  The gauges look good to me.  Sounds like you have figured out how to use them.

It will take a few times to get the hang of it to where it takes only a couple minutes to do

Just curious, have gauges been synced?  They have to be synced first.  You can do this one gauge at a time or if you have or can find something like in the image, you can do them all at once.

I don't have a motorcycle, sold it ('85 Yamaha Venture Royale).  Haven't had a CB750 for over 40 years.

The guages have to be synced?  I thought as long as they're all built identically this wouldn't be necessary?

All the manuals indicate 1500-2000rpm at operating temp for the vacuum sync.
