If it makes you feel any better, I know my engine is a "...ury". Most of those labels fall off in their entirety, for some bizarre reason, the top right corner of mine is still clinging on......
Number on the head is (or should be) the same as the one on the leg. It's a bit like modern Ford cars where you can see the chassis number in the windscreen, but it's also stamped on the floor under the carpets.
I'm going from memory here, but that looks like a Yam respray type serial number, in which case with a number like that, I wouldn't loose sleep over invalidated warrnaty!
