Hello all, I have this bike and I'm not sure what it is.
Engine and frame numbers match 510-004458
Thinking its a 76 yz400 but want to make sure before I part it out.
Thanks guys!

Thanks, I appreciate the info.
Whole bike is up for grabs if anyone needs parts.
Motor was a good runner before the stator took a dump 10 years ago.
Has good compression, piston looks like new!
Probably wouldn't need much more than seals.

Looks like a 1975 MX400B to me. It's still worth doing for vintage MX, too bad it's in CA though.
