I think I posted a while back about assuming when it comes to the go-tec/mg66 line of engines. Was out running in some new clutch shoes when the engine started lean bogging. First thought? What's wrong with my engine? Turns out nothing. When I got it back inside found the the pressure hose from the pipe had rubbed up against the new clutch bell, producing a hole in it. So again to all those that cry that the engines are unreliable it's most likely the nut behind the wheel.
