The items that we are selling here is a great item if you are working on, restoring, riding or racing your 1968-1972 DT1 and 1972-1973 DT2 or DTMX.   Helpful TOP  and BOTTOM engine gaskets. This may fit earlier models if your bike uses this style head gasket.  Top quality aftermarket item. Item will ship sealed in the package, I just opened up an extra to take the photo.  This set includes the important and expensive copper cylinder head gasket and exhaust gasket, engine case cover gasket, and cylinder base gasket.  You get everything seen in the photo to help your engine keep on revving! We also stock the complete crankcase oil seal kit for this bike too if you may need? This gasket set used the head gasket style part # 214-11181-00. Some DT's used a different shape gasket in different years so check/ confirm that this is the correct on your bike. It should be correct. The other style of copper head gaskets for on some models of DT1 DT is very different..it is just a copper round disc. This set uses the head gasket with 4 holes for engine studs. Hope that helps.  That is it!
