Exhaust compability? 81 and 83 gs750

[bexabarr]

Does anyone know if an exhaust (vance 4 to 1) from a 83 gs750es will fit my 81 gs750e?

The '83 has a smaller port diameter. I guess you could make up some spacers to fill the gap. The '83 is a more compact engine in every respect so how it fits under the pan might be a problem as well though I can't confirm that.

Well I guess I'll just have to keep looking.... I found a good deal on an used 83 exhaust and almost jumped on it. Your post came in just in time. Thanks.

You could probably use an 1150 exhaust. The port size should be the same and dimensionally would be a better fit.
