GS650g Compatability

[Raxus]

Hey Gang,

Was wondering what years and models are compatable with my '81 GS650G? Or am I totally off the mark and only same model/year works with these bikes?

For what parts?

The GS650G is an odd ball. Shares a lot of electrical, brake, body parts with other GSes. But its engine and transmission are unique designs. Even with that, some internals are probably shared.

And you even have to be careful within the same year. :shock:

The 650 (chain drive) and the 650G (shaft drive) have different bottom ends.
The chain drive model uses roller bearings and low oil pressure, the shaft drive has plain bearings and high oil pressure.

Other than the obvious differences in output shafts on the transmissions,
I don't know what other parts are different in the engines.

Mainly just cosmetic stuff. Tho it would be nice to know just in general. Like the older cars that some years you couldi nterchange.

I'm sure that some mechanics with lots of GS experience could tell you right off. For the rest of us, it's necessary to use the fiches that are available on-line at Alpha Sports and at Bike Bandit. Look up the part number for a given part on the GS650G and then find the part number for the donor bike, and see if they match.

Someplace I came across an Ebay store that sells both fiches for motorcycles, and a computerized parts cross-reference. I think that the cross-reference was about $20. I don't remember where the store is.
