Maintenance & Technical > KX500 Original

AARG! Ive got a cracked head on my 1990 500.

(1/1)

BMH:
Ok here is the deal I bought this 500 after a shop rebuilt it. the spark plug gap kept closing and looked pitted. so I pulled the head and jug and the inside of the head is pitted really bad as was the piston. so I pulled the jug and the piston had a gouge below the rings vertically about 2 inches long on the rear. the jug has a crack on the air intake side of the piston. Toast so i am looking for a head and jug top end rebuild kit any Ideas would be appreciated I will post pics when I can. :? Oh yea about 10 hrs. total time on rebuild.

US Chrome can fix and replate the cylinder for your I have had them weld up a few cylinders for me. They all came out great and I never had any problems with any of them. They charge a couple extra bucks for the welding.CBX
