Where to find parts for a 1980 Suzuki GS850G motorcycle?
I doubt if you will find the parts you need at a store, not when the parts are over 28 years old, so why not start calling all the junk yards in your city and ask them if they have any “basket cases” (totalled motorcycles) and if they do, then perhaps they would also have the part that you are looking for. If not, then you may have to use your imagination and improvise the part that you need.
