Faults:

The rectifier unit failed.

The swing arm bushes were worn out.

The carburettors started to leak.

One of the rubberized intake manifold cracked.

General Comments:

The handling is excellent (unbelievable at first).

The bike is very reliable.

Somehow, parts are still available!

Will keep going as long as you want it to.

Never never ignore maintenance.

Ex-owners have regretted selling it.

Of course, the GS550 cannot be compared unfavorably with the latest bikes.

It is almost human.
