ATHENA Engine Oil Seal Kit for KAWASAKI KX 500 1989-2004

The ATHENA P400250400500 engine oil seal kit is designed for KAWASAKI KX 500 from 1989 to 2004. Oil seals (or lip seals) seal around the shafts that come out of the engine: crankshaft, countershaft, gear shift shaft, kick-start or water pump. On a two-stroke, the crankshaft seals also keep the bottom end airtight, which it needs in order to run.
