Can I install a Delkevic 4-1 on a G model GS1000...they list E and S availability

[Guest]

I have to laugh because this is off to me...for once I can find parts for my '80 850G and not for the 1000G.
I had an ebay auction saved for the possibility of a Delkevic 4-1 on my 850G, but I like my 4-2 oem system even if it is less than perfect.
I double checked not on ebay and Delkevic's site....no mention of an exhaust system for the 1000G...but they do make one for the 850G! {which never seems to get high perf parts support}.

So, has anyone managed to mount a Delkevic system on their 1000G model?
What is the difference in the S and G models....both 2 valve right?

Help...

They used to have one for the 1000G, the 850 is a recent addition. You should contact them, maybe they are just out of stock.

They're probably identical.

I've read that bolt spacing at the exhaust ports are different on the heads, so the flanges would need to have the holes slotted.

1100E and 1000G headers are the same. The rear mount will have to be fabricated but I have an 1100E exhaust on my 1100G engine in my 1000G frame. The rear mount is simple to make. Just a simple metal strip with two holes is all that's needed.

Ah, now that's interesting! A guy got back to me from Delkevic and said that the header wouldn't work since the brake arm would hit it.
Funny thing, I have the basics for rear sets and lack only the mounting plates to be complete.....so my next issue would be where the exhaust would have to mount up.
What muffler did you end up with? Yours looks different from the one I saw...{spose a link would be a good thing huh....}
Here's what I was looking at- "header only"

...and this muffler might look neat behind it...

Here's an '82 4-1 system for a "G"....any head mount difference on this year to an '80?

So, to make sure I read this right- 1100E/1000G/1100G all mount the same on the motor?...right?!
Your reply said "1100E and 1000G were the same"...but then you said you had an 1100E exhaust system on your "1100G" motor in a 1000G frame...three different pieces, so to speak.
Just wanted to clarify what you wrote so I know which exact exhaust system to pull the trigger on.

The frame is a 1980 GS1000G. The engine is an 1100G engine. There are no external differences between the 1000 and the 1100 G engines, so everything is a straight bolt up. Same carbs, same exhaust. Different jetting. The exhaust I have on my bike is a Vance & Hines for a GS1100E. The only changes I needed to make is at the rear mount. No interference issues were observed.

Great...thanks for clearing "my" head {been a long day}. I'll wind up buying the 1100G set up and hope Delkevic has the same bends as your V&H.
Honestly speaking - I can't see why the '82-on cycle would be laid out much different than the '80...'82-on has the aluminum pass foot peg plates while my '80's have the frame hoop for those.
I guess there's only one way to find out then!..........the left over money from not buying a V&H pipe will go elsewhere on this bike!

Member only7bikes has a Delkevic on his 1000G. He had to make 1 small modification but I don't remember what it was or which pipe he used. You might PM him, name is Steve.

Was out trying to install the replacement kickstand and trying to figure out why the front bolt threads for it are gone.....so...let's mess with the new exhaust system now instead!




The '82 on gs1100G system does fit. The mount needs tweeking though.

[80GS850GBob]

I sort of have a back up plan utilizing a late model peg plate if I cut off the current '80 hoop there. Would also require the same year brake arm.....I plan on rear sets anyway.

oooohh that's a nice muffler, my buddy is looking for a complete setup for his GS1000G.
No hurry, we took the engine out for new Wiseco's, top end revision and painting so i will follow this with interest !

Would be great for one of my GS1000 chain bikes, too

Sounds like Delkevic support knows their stuff and is helpful too
