Vance & Hines on my Gs1000

[GS1000G]

Hey everybody. i have a 1980 gs1000g, i just put a new vance and hines 4-1 exhaust. when i pulled off my old exhaust some weird shim semi-circle thing around the 2 center exhaust ports, i pulled the old exhaust off, put the new one on and got an exhaust leak. i cant figure it out so i thought i would ask you guys, and yes i did install new gaskets and cleaned the ports

Can you take a photo, or did you put them back in?

i tried it both ways with no difference, it didnt have the same spots for them as the factory system but they did fit in

Grab some exhaust crush gaskets and see if that helps.

[GS1000G]

i threw new ones in when i put the system on

Generally, with aftermarket exhausts, you may need to re-torque the manifold bolts after running a bit, even with new gaskets.

so just let it leak while it runs then try and re-tightnen it?

If you did not get the old gaskets out they won't be even and leak.
