1980 750 LTD frame # doesn't match motor

So I was looking at my frame number for insurance purposes and I noticed that the frame and engine number do not match. I am 90% sure this is the original motor in the bike...

Is this normal?

I believe that it's almost imposible to get exact matching of engine and frame numbers. Possibly being within a few thousand # would be close.

For example, on my 82 GPz1100 B2 the frame # starts out at JKAKZBB11CA0***** and the engine is KZT10BE0*****

oh, so is that why they make such a big deal out of cars that match?

makes sense... my frame and motor are about 8,000 different

On cars when they say "numbers match" they really mean the engine, tranny, etc. is within the correct range for the body number. So for example a 327 Chevy engine from a later model car may not be the "correct" engine for an earlier model Chevy that came with a 327 because the later engine may have minor internal differences even though it's the same displacement.

It's a different story with firearms by the way. Matching serial numbers mean just that - exact match for every part on the gun. Ed
