All the threads are checked and verified. Valves are grinded, and adjusted (you don't have to re-shim). Valves seals are new, and the decompressor seal is also new.
It's sandblasted and painted.
It doesn't include new cylinder head joints (the rubber joint of the cover and the metallic one) and the rubber caps included are not new. We sell these joints apart and the rubber caps if required.
It's made under order.
