I just bought a ´81 z750 from a friend of a inlaw for $800. Came with spares including a set of carbs,speedo cable,side covers,ductail,brake disc,bikini fairing,cushion rubbers for sprocket/back wheel,mirrors etc.. Have owned ´81 z250´s before & loved them, hope their big brother is as much fun. Oh! it has been bored-out to an 810. Is there anything I should watch out for or will this just be the start of more good times on the road?
