Tires???

[dustywang]

Im looking to replace my 35 year old OEM tires on my 76 Kz400. Looking for what tire size I should replace with? Stock is 3.25 18 front and 3.5 18 rear. I was looking at 100/90/18 front and 120/90/18 rear.

Way too big. You need to know your rim width (measured on the inside of the lip or stamped somewhere on the outside). Check this chart out from Hagon:
