Experience is the best teacher. Good information........especially for a GZ that is still stock. Some folks also notice that the exhaust pipe is getting WAY hotter than normal.

Don't think this applies to those of us who have added 1 tooth to the front sprocket, however. It's doubtful that ALL of us have the valves set too tight!
