Not your normal number.
A picture of that would be helpful...

Think you've missed the prefix numbers off there should be some some numbers and maybe a letter or two before these numbers

Have a look here. Looks like a 78 or 79.

From the factory the engine number and the frame number matched. They may not now. Not a problem. Just as long as you know what you have.
Yours is a 447 series engine. so most any part from 74 up is an easy swap.

You need to look over that front brake, wheel, caliper, rotor combination carefully, theoretically that (72-76) rotor cannot be used with the 79? caliper, fork you have. It has the wrong offset to work there. The face of the rotor may be evidence of centering problems.

Look closer Gary, I don't think that's a Yamaha disc or caliper. Similar looking but not the same. The whole front wheel could be off some other brand bike.
