This is a very helpful and hard to find engine oil seal kit for the now vintage Yamaha 1974 DT250 250cc  and DT360 2-Stoke models. Please note this is correct only for 1974 year DT250. If you have an earlier or later DT250 bike/ engine..we do have those seal kits on our website too. This set is correct for all DT360 engines. You get both (left and right) Crank seals, primary drive (Sprocket) output shaft seal, Shift seal, Clutch seal and  Kick Start shaft seal. Teflon lip seal used as original on crank seal.  New seals that will seal up your engine perfectly not 40 year old seals. You and your bike will be happy!  We only sell the best! Top quality aftermarket item. This is an essential item if you are riding, racing or restoring one of these cool vintage Yamaha's!  That's is it!  Back to the garage for us!
