so how is everyone liking their fz's? any problems? hows the reliability? personally i've gotten 4237 miles and nothing has gone wrong other than a burnt out plate light. btw what do you guys tend to shift at? personally i feel 3-4k seems perfect and im always scared to take it any further afraid of breaking anything. how does the engine hold up to you guys at higher rpms? and another think, does anyone have a rough vibration at about 3500 - 4000 rpm?
