Number question

Just kinda curious ......... how does having matching numbers ( frame and motor, same number ) effect the value of a 1975 XS650 ?, and why ?? Looking at buying another here abouts, but the owner wants way too much for his dead hulk ...............

Opinions ??

Thanks

John

It shouldn't affect anything. These bikes aren't really collector items yet. If you plan to keep it vintage and restore everything then it would be nice. Otherwise it doesn't matter.
