The item that we are selling here is a helpful item if you are restoring, riding or racing your now vintage Kawasaki KZ400 Motorcycles.   This is a new clutch pushrod Oil Seal for the 1974-1977 KZ400 models. This will also fit some early production KZ400B 1978 models.    This Oil Seal Kit is correct for all models built in  1974 1975 1976 1977.  Top quality aftermarket item. We only sell the best!  This also fits some the EARLY production 1978 B models.  Regarding 1978 Models, Kawasaki did a running change in the engines in this year. So if you have a 1978 model check  your engine serial #, as this set is correct for engines starting with with number 141330 and earlier.  If you have a 1978 or 1979 model with engine serial # 141331 and higher this engine takes a different seal we do have this item too in our store as a different part #.
