The thing to watch on the GZ is the carb. Make sure you add some carb cleaner to the fuel every three or four fill ups. A gunged up carb seems to be the most common fault on this bike. Also. don't forget, when switching off the engine, to not turn the key all the way to the left. This locks the steering but puts the rear light on. The correct position is one click before full left. To lock the steering but without tail light. You might also get a spray can of contact cleaner, and spray it into the red cut out switch, the clutch safety switch, and the side stand safety switch, as these frequently jam up.
