Default Re-using copper head gasket?

     

So i just replaced the head gasket on my cr125 when i replaced the whole top end. It ended up running great but it leaks black liquid from the bolts so i bought a new head gasket. The new one wasn't Aiseco like the one that leaked was but it didn't fit because my bike is bored out and i cant buy a new gasket anywhere unless i buy an entire kit which I don't need.
Can i re-use the gasket? Why is it leaking? I took it off because i thought it was on wrong but it wasn't, so I' wondering if maybe it wasn't broken in and will go away?
Thanks,
Isaac

Copper head gaskets can be reused if annealed...heat it up till she turns colors and quench it in water or oil or just air cooled...burnish the color off with a scotch brite pad, coat with Coppercote and install...JMO

If it is symmetrical, turn it over too.

Well we ended up ordering a new one anyway, and now my question is why? why did it leak through the bolts? Does it just need to heat up? Could i have installed it wrong? The raised bumps go up and the tab toward the back. I don't want the new one to leak.

Bump..I would really like to know if there is something i did wrong or any reason why it leaked? I don't want to waste another $30 for the head gasket and have it leak again.
Thanks
