Yamaha AT3 125 sidecover Oil tank sku 1974

I believe this will fit 1972-1974 DT125 models, the ones with the electric start. Nice paint  with a few small scratches for the area that would be under the decal.  It includes its hard to find Yamaha branded oil cap(an edge is broken off .  It had  one  1/8" pinhole located 1 inch down from the very top level in the back of the tank.  This spot  would actually be below the level that most would fill it.   It is shown in a picture and  has been covered with metal and then strongly epoxied.  It will not leak.
