GS1000 airbocx

[stng_96]

Hey guys, Just bought my second Suzuki GS, its a 1980 GS1000e, tank lined, painted, rear piece painted, carbs rebuilt, new battery, plugs, good tires, 30k miles, picked it up yesterday for 400 bucks. It has pod filters on it now with stock jetting, and cut off mufflers, my plan right now is get it to stock and get it running right, so I am curious, what years of airbox will fit on it. Will a 78 airbox fit on my 80? Same questions for exhaust? I searched the forum here, but I didn't have much luck. I used to have an 83 GS650e, so I am not completely a newb when it comes to these bikes!

Thanks!

The 1980 is a one year wonder, due to the CV carburetors. You might be able to enlarge the holes in an earlier air box to fit the larger boots.
Other than the hole size and the chrome decorations, I believe it is the same.

Hmm, good to know, So are the typical tuning issues that plague these bikes an issue with that unique carb setup?

Due to the air filter housing location directly over the battery, I think pods make sense on those. I'm putting them on a '78 I just picked up. Plus, it has couple missing and damaged parts in the air box/filter housing set up anyway.

I've never actually seen a 1980 1000E. I know they were made, but have never seen one.

The carbs are not unique. They are pretty much like all the CV carbs on every Suzuki (and other brands) starting in '80 pretty much. It is just unique on the 1000E (and 1000S) for that year. Previous 1978 and 1979 1000's had slide carbs, not CV's. Every 1000G, 1100E, 1100G, etc. has them.

Ill post a picture when I get home tonight, I think it looks pretty sharp.

It's not unique, the CV carbs started in 1980 and continued for several years. The last year of the 1000E was 1980, and they didn't sell very many as the 1100E and 1000G also came out that year. I don't know of any tuning issues, they are very easy to tune. An 1100E air box might be the same, check the part numbers. It's easy to find air boxes for those.

Stock for me. I had one years ago with pods and a VH pipe. Jetting was ok.
@stng_96 I'm glad you saved another one.

'80 E/S 1000 airbox unique for this year... and indeed rare. Try posting in Parts Wanted section; forum member had one for mine.

The rear air box is common between the 1980 CV carb bikes and the '78 & '79, but the front airbox section is different. As Tom says, the front airbox could be modified by opening up the holes so the larger boots will fit, the problem with doing this is determining how large to make the holes. It's critical to avoid any airleaks in the system otherwise the bike won't run right.

 

[stng_96]

Would the airbox from an 81G work? I know the design is a little different, with no rear airbox section, but if the carbs are the same, it should work find right?

I'm pretty sure the shaft drive airbox won't fit in a chain drive 1000 frame.

 

[stng_96]

Ok thanks, good to know, wonder if I could modify that box it any way....

Pretty sure that I have another one, not nearly as nice of condition though.
You might want to find better condition chrome end caps or paint.

I'll try to compare the two and report back. Pretty sure that they work myself.

Let me know daniel, a halfway decent 80 airbox setup is proving a challenge to come across when i dont want to trade my first born for it.

I have a modified G airbox on my gs1000 with slide carbs. I cut out the front and welded tubes slightly bigger than carb inlets, made up rubber gasket tubes a squirt of WD40 and it squeezes together. 10 years its been like that no problems after i jetted up after a 1085 upgrade. And a storage box sits where the air filter was.

 

[7981GS]

I am fairly certain that this '78 box is still kicking around in my shop...

As Frank was doing a Cooley restoration, and planning on keeping the bike, not flipping it,
he was able to pry the shinny one from my hands.

I might even still have a filter box (no lid), with coupler/clamps, to go with it if needed.

Thanks for the offer Dan, but based on the first few posts in this thread, I think the ports for the carbs on the 78 and 79s were a little smaller then the 80's.

UK GS Nut, so was the front different, or a different spot that touches the frame? Seems to me that since the carbs were the same, you wouldn't need to change the front of it, and it something hits the frame, I could just modify the box to go around that obstruction.

Thanks guys

Why not get a dremmel and open up the holes a little? Hardest part will be figuring out how large to make the holes. I have some old airbox boots and should be able to give you an idea on how big to make the holes.

 

[stng_96]

Well I could do that, but I hadn't really looked much at that option due to the fact that I usually see those new boots and clamps bringing a good amount by themselves, then I'd need front box from an older one, then Id also have to find the back section of the airbox assembly. If I could modify a front piece from an 81, that'd be all I need.
