The item that we are selling here is a great and an essential item if you are restoring, riding or racing your now vintage Kawasaki F8 Bison (250cc)  from 1971 and 1972. These were some great 2-stroke motorcycles that Kawasaki made! This is a great 7pc engine Oil Seal Kit. This contains the Right Crank seal, Left Crank Seal, Sprocket Seal, Kickstart Seal, 2 pcs of the Shift Seal since these bikes used a left and right side seal..and Clutch Pushrod Seal. Top quality aftermarket item, new, not 40 years old seals. Get your bike up and running nice. Old seals suck air and can easily damage your piston.  We  look forward to doing business with you!  Please see the photo to see all of the great items in this kit! We also have the F8 gasket set on our website if you need also?
