I believe they should the same as I seem to remember a friend bought a new YZF750 in 1996 and the numbers never matched, I had bought a new YZF750 in '94 which did match.

So I called to Yamaha and was told that '96 was the first year that numbers stopped being matched.

It is because thats when they stopped producng engines and frames in the same factory.

They used to get numbered at the point of assembly, so could be matched at that time.

When engines and frames are made in different locations around the world, they are already numbered and so cannot be matched at point of assembly.

Especially for models that have common engines in different frames or one frame that takes different engines.

engine number/ frame number should match on a yamaha machine of that year. have had few old yamahas. engine frame numbers always matched. yamaha was the only manufacturer using matching numbers. up until about 2000
